Jack Russell Terriers are energetic, intelligent and full of character. It is therefore not surprising that they have been crossed with many other dog breeds.

Some Jack Russell mixes are small companion dogs, while others are athletic working crosses that need several opportunities to exercise every day. However, crossing two breeds does not produce a predictable combination of their best characteristics.

A mixed-breed puppy can inherit any blend of its parents’ appearance, temperament, energy level and health risks. Even puppies from the same litter may grow into noticeably different dogs.

This guide explores 15 popular Jack Russell Terrier cross breeds and what prospective owners should consider before adopting one.

Important: The descriptions below explain possible characteristics, not guarantees. Always assess the individual dog rather than choosing one based only on the crossbreed’s name or appearance.

Quick Comparison of Popular Jack Russell Cross Breeds

Individual dogs may fall outside these general descriptions.

What Is a Jack Russell Cross Breed?

A Jack Russell cross is a dog with one Jack Russell Terrier parent and a parent belonging to another breed—or a dog believed to have ancestry from both breeds.

Names such as “Jack Chi” and “Jackapoo” are informal labels. They do not create new standardised breeds. There is usually no official standard controlling the mix’s adult size, coat, temperament or appearance.

The Jack Russell Terrier is a small working terrier developed for hunting. It is generally lively, alert, bold and physically active. The breed may have a smooth, broken or rough coat, with white as the predominant colour. The Royal Kennel Club describes the Jack Russell as a strong, active and flexible working terrier.

Those traits can remain influential when a Jack Russell is crossed with another breed, but genetics do not work like mixing equal quantities of two ingredients. One puppy may strongly resemble the Jack Russell parent, while another may take after the other breed.

Are Jack Russell Mixes Good Family Dogs?

Some can make excellent family companions, but suitability depends more on the individual dog than the crossbreed’s name.

Before bringing one home, consider:

• the dog’s behaviour around children;
• previous socialisation and training;
• tolerance of handling and noise;
• prey drive around smaller animals;
• guarding tendencies;
• daily exercise requirements;
• ability to settle inside the home; and
• whether adults can supervise interactions with children.

Jack Russells can be fast, determined and easily excited by movement. A mixed dog may inherit these tendencies. Young children should never be left unsupervised with any dog, regardless of its breed or size.

Do Jack Russell Mixes Shed?

Many do. Crossing a Jack Russell with a Poodle or another low-shedding breed does not guarantee a low-shedding or “hypoallergenic” puppy.

A puppy may inherit:

• a short, smooth coat;
• a wiry or broken coat;
• a soft, curly coat;
• a longer coat;
• or a combination that is difficult to predict.

Dogs with curly or continuously growing coats may shed less visibly, but they often require more brushing and professional grooming.

1. Jack Chi: Jack Russell Terrier and Chihuahua Mix

The Jack Chi combines two small dogs with confident personalities. Although compact, this mix should not automatically be considered a quiet lapdog.

A Jack Chi may be affectionate and closely attached to its family. It may also be alert, vocal, wary of unfamiliar people or inclined to chase small animals. Early, positive socialisation can help the puppy develop confidence without becoming overwhelmed.

Because both parent breeds are small, the adult dog will usually be compact. However, its body shape, ear position, coat and weight can vary considerably.

Possible Jack Chi characteristics

• Small, portable body
• Alert and expressive personality
• Strong attachment to one or more people
• Moderate to high energy
• Potential barking or watchdog behaviour
• Possible sensitivity to cold weather

Health considerations

Small dogs can be vulnerable to dental disease and kneecap problems such as patellar luxation. Chihuahua ancestry may also introduce additional heart, eye or neurological concerns.

A responsible breeder should arrange appropriate health screening for both parents rather than assuming that mixed puppies are automatically healthier.

Best suited to

A Jack Chi may suit an owner who wants an interactive small dog and is prepared to provide training, appropriate exercise and careful handling.

2. Jug: Jack Russell Terrier and Pug Mix

A Jug is a cross between a Jack Russell Terrier and a Pug. This mix may combine the Jack Russell’s busy nature with the Pug’s sociable, companion-oriented personality.

Some Jugs have a longer muzzle than a typical Pug, but this cannot be assumed. A puppy that inherits a shortened muzzle may still experience breathing difficulties, heat intolerance, eye vulnerability or skin-fold problems.

Possible Jug characteristics

• Small, sturdy body
• Playful and people-oriented nature
• Moderate energy
• Food motivation
• Smooth coat with regular shedding
• Possible stubbornness during training

Health considerations

Breathing should be taken seriously. No dog should be considered healthy simply because its muzzle is slightly longer than another Pug’s.

Warning signs include noisy breathing at rest, struggling to recover after light exercise, disturbed sleep, gagging, repeated overheating or collapse. These signs require veterinary attention.

Best suited to

A Jug may suit a home looking for a playful companion, provided the owners can manage its weight and avoid strenuous activity in hot weather.

3. Jackapoo: Jack Russell Terrier and Poodle Mix

The Jackapoo is normally produced by crossing a Jack Russell with a Miniature or Toy Poodle. The size of the Poodle parent makes a significant difference to the puppy’s likely adult size.

Both parent breeds are intelligent and energetic. A Jackapoo may learn quickly, but intelligence does not always make a dog easy to own. Clever dogs can become skilled at escaping, demanding attention or creating their own entertainment.

Possible Jackapoo characteristics

• High intelligence
• Playful, people-focused behaviour
• Strong need for mental stimulation
• Wavy, curly, wiry or mixed coat
• High trainability when properly motivated
• Possible chasing or digging behaviour

Grooming needs

The coat may mat if it is not brushed thoroughly. Some Jackapoos require professional grooming every several weeks, particularly around the face, ears, legs and areas of friction.

The mix is not guaranteed to be hypoallergenic.

Health considerations

Depending on the Poodle parent’s size and family line, health screening may include examinations for eyes, joints and inherited genetic conditions. Jack Russell screening may include tests for primary lens luxation and inherited forms of ataxia. The Royal Kennel Club lists breed-specific DNA testing options for Jack Russell Terriers.

Best suited to

An active owner who enjoys training, interactive games and regular coat maintenance.

4. Jackshund: Jack Russell Terrier and Dachshund Mix

Sometimes called a Jackweenie, the Jackshund combines two breeds developed to pursue animals underground. The result may be a determined little dog with a strong nose, prey drive and independent streak.

Its body shape is unpredictable. Some inherit a relatively balanced build, while others develop the Dachshund’s longer back and shorter legs.

Possible Jackshund characteristics

• Curious and determined temperament
• Moderate to high energy
• Strong interest in scents
• Digging and chasing behaviour
• Smooth, wiry or longer coat
• Potential barking

Health considerations

Dogs with long backs and short legs may be more vulnerable to spinal problems. Keeping the dog lean, using suitable exercise and discussing any mobility concerns with a veterinarian are important.

Seek veterinary attention if the dog suddenly cries out, becomes reluctant to walk, develops weakness, drags a limb or loses bladder or bowel control.

Best suited to

A patient owner who can provide reward-based training, scent games and a securely fenced outdoor space.

5. Jackabee: Jack Russell Terrier and Beagle Mix

The Jackabee combines a working terrier with a scent hound. This can create an enthusiastic, active dog with a powerful interest in smells and moving animals.

A Jackabee may be friendly and playful, but reliable recall can be challenging. A secure lead or enclosed exercise area is often necessary.

Possible Jackabee characteristics

• Small-to-medium build
• Strong scenting ability
• High activity level
• Food motivation
• Friendly but independent personality
• Potential howling, barking or digging

Health considerations

Monitor body condition carefully because some Beagles are highly food motivated. Ear care may also be important if the dog inherits longer, folded ears.

Best suited to

An active household that enjoys walking, scent work and outdoor activities—and has secure fencing.

6. Cojack: Jack Russell Terrier and Corgi Mix

A Cojack is commonly a cross between a Jack Russell and a Pembroke Welsh Corgi. Both parents are active, intelligent dogs originally developed to work.

This mix may attempt to chase, control or nip at moving feet, particularly if it inherits herding tendencies. That behaviour should be redirected through appropriate training rather than punished.

Possible Cojack characteristics

• Small-to-medium body
• Short or moderately long legs
• Alert and confident personality
• Strong interest in movement
• High intelligence
• Regular shedding

Health considerations

Some Cojacks inherit a longer back or shortened limbs. Weight management is especially important because excess weight places additional strain on the spine and joints.

Best suited to

Active owners who enjoy structured training and can provide both physical exercise and problem-solving activities.

7. Border Jack: Jack Russell Terrier and Border Collie Mix

The Border Jack is an intense and athletic mix. Both parents were developed to work, although they perform very different jobs.

This dog may inherit the Border Collie’s sensitivity to movement and the Jack Russell’s speed, persistence and prey drive. Border Jacks are sometimes seen in dog sports because they can be fast and highly responsive.

However, this is not necessarily an easy family pet.

Possible Border Jack characteristics

• Very high physical energy
• Exceptional learning ability
• Strong focus on toys or movement
• Need for structured mental stimulation
• Possible sensitivity to noise or environmental changes
• Difficulty relaxing without appropriate training

Health considerations

Repetitive high-impact exercise should be introduced carefully, particularly while the puppy is still growing. Fitness does not protect a dog from injury caused by excessive jumping or abrupt twisting.

Best suited to

An experienced, highly active owner interested in advanced training, agility, flyball, scent work or other structured activities.

8. Jack Tzu: Jack Russell Terrier and Shih Tzu Mix

The Jack Tzu combines a working terrier with a companion breed. The result may be affectionate and playful, but coat type, exercise needs and facial structure can vary.

Some Jack Tzus have a longer, softer coat requiring frequent brushing. Others inherit a shorter or wirier coat.

Possible Jack Tzu characteristics

• Small body
• Affectionate companion temperament
• Moderate energy
• Long, wiry or mixed coat
• Possible independent streak
• Potential alert barking

Health considerations

If the dog inherits a shortened muzzle, monitor breathing and heat tolerance. Prominent eyes may be more vulnerable to irritation or injury. Regular dental and eye care may be necessary.

Best suited to

A home seeking a small companion that still enjoys walks, games and training.

9. French Jack: Jack Russell Terrier and French Bulldog Mix

French Jacks can vary considerably in body shape and breathing ability. Some resemble a sturdier Jack Russell, while others inherit the French Bulldog’s shortened muzzle, broad chest and compact build.

This cross should not be promoted as a way of producing a “healthier French Bulldog.” Individual puppies may still inherit serious structural and hereditary health problems.

Possible French Jack characteristics

• Small, muscular body
• Playful personality
• Moderate activity level
• Strong attachment to people
• Smooth coat
• Possible breathing and heat limitations

Health considerations

Potential concerns include obstructed breathing, spinal abnormalities, skin problems, eye injuries and overheating.

Choose a breeder who prioritises functional breathing, natural movement and health screening—not exaggerated features or unusual colours.

Best suited to

Owners who understand heat safety, carefully monitor exercise and can afford potential veterinary care.

10. Bo-Jack: Jack Russell Terrier and Boston Terrier Mix

A Bo-Jack may be social, amusing and energetic. Both parent breeds often enjoy interacting with people, although individual temperaments vary.

Dogs inheriting the Boston Terrier’s shorter muzzle may have reduced tolerance for hot weather or prolonged exertion.

Possible Bo-Jack characteristics

• Small, compact body
• Playful and people-oriented temperament
• Moderate to high energy
• Short, easy-care coat
• Potential jumping or excitable behaviour
• Possible breathing limitations

Health considerations

Monitor breathing, eyes, kneecaps and skin. Exercise should be adjusted to the dog’s individual breathing ability and the weather.

Best suited to

An interactive home that can provide regular training, play and companionship.

11. Yorkie Jack: Jack Russell Terrier and Yorkshire Terrier Mix

The Yorkie Jack combines two terriers, so prospective owners should expect more than a decorative lapdog.

This mix may be bold, energetic and quick to react to sounds or movement. Despite its small size, it needs training, enrichment and appropriate exercise.

Possible Yorkie Jack characteristics

• Small body with a large personality
• High energy
• Alert barking
• Strong prey drive
• Close attachment to family
• Silky, wiry or mixed coat

Health considerations

Dental care is particularly important in small dogs. Other potential concerns include kneecap instability, eye disease and problems associated with very small body size.

Avoid breeders deliberately producing extremely tiny puppies.

Best suited to

Someone who appreciates terrier behaviour and wants an active small companion.

12. Cocker Jack: Jack Russell Terrier and Cocker Spaniel Mix

A Cocker Jack may combine the Cocker Spaniel’s sociability with the Jack Russell’s energy and determination. Many require more exercise and enrichment than their appealing appearance suggests.

Possible Cocker Jack characteristics

• Small-to-medium body
• Friendly, lively personality
• High interest in outdoor activities
• Feathered, smooth or wiry coat
• Strong interest in scents and movement
• Need for regular grooming

Health considerations

Long or heavily coated ears may be more prone to moisture retention and infection. Regular ear checks are useful, but owners should not insert cotton buds or unprescribed cleaning products into the ear canal.

Best suited to

An active household prepared for exercise, training and coat care.

13. Jackador: Jack Russell Terrier and Labrador Retriever Mix

Because the parent breeds differ substantially in size, Jackadors can vary widely. Some are medium-sized and athletic, while others may be larger than prospective owners expect.

A Jackador may be friendly and enthusiastic, but it can also inherit the Jack Russell’s chasing instincts or the Labrador’s exuberance and appetite.

Possible Jackador characteristics

• Medium and athletic build
• High energy
• Food motivation
• Sociable personality
• Strong retrieving or chasing behaviour
• Regular shedding

Health considerations

Joint health, body weight and exercise during growth deserve attention. Prospective owners should ask about health testing performed on both parents, including screening appropriate for Labrador Retrievers.

Best suited to

Active households that enjoy hiking, outdoor games and consistent training.

14. Staffy Jack: Jack Russell Terrier and Staffordshire Bull Terrier Mix

The Staffy Jack is likely to be strong, energetic and people-focused. Its adult size and build can vary, but many are more muscular than a typical Jack Russell.

A Staffy Jack may be affectionate with people while still requiring thoughtful socialisation and careful introductions to other animals.

Possible Staffy Jack characteristics

• Compact, muscular body
• High physical energy
• Playful and affectionate nature
• Strong pulling or jumping if untrained
• Possible prey drive
• Short coat

Health considerations

Potential concerns may involve the skin, joints, eyes and kneecaps. Owners should also keep the dog lean and build fitness gradually.

Best suited to

An experienced owner able to provide reward-based training, secure handling and daily physical and mental activity.

15. Mini Jack Schnauzer: Jack Russell and Miniature Schnauzer Mix

This mix may also be called a Jack Schnauzer. Both parent breeds are alert, energetic and historically associated with controlling vermin.

The result may be a clever watchdog with a strong desire to investigate its surroundings.

Possible characteristics

• Small, sturdy body
• Wiry, rough or mixed coat
• High trainability
• Alert barking
• Strong prey drive
• Need for regular exercise and enrichment

Grooming needs

Dogs with a Schnauzer-like coat may need regular brushing, clipping or professional grooming. Hair around the face should be kept clean and comfortable.

Health considerations

Potential risks depend on the health history of both parents. Responsible breeders should screen for relevant eye, joint and inherited conditions.

Best suited to

An owner who enjoys training and does not mind managing grooming or alert barking.

Which Jack Russell Cross Breed Is Best?

There is no single best Jack Russell mix. The right dog is the one whose actual behaviour, exercise needs, size and health fit your household.

Do not rely only on appearance or promises that a cross will combine the “best of both breeds.”

Ask yourself:

1. How much exercise can I provide every day?
2. Can I manage a strong prey drive?
3. Do I have a secure garden or safe exercise area?
4. Can I afford grooming if the dog develops a high-maintenance coat?
5. Is my home suitable for barking or excitable behaviour?
6. Do I have young children, cats or smaller pets?
7. Can I afford insurance and unexpected veterinary treatment?
8. Am I prepared to train an intelligent but independent dog?

Are Jack Russell Cross Breeds Healthier?

Not automatically.

Genetic diversity may reduce the likelihood of certain inherited problems in some circumstances, but a mixed-breed dog can still inherit health conditions from either parent. It may also inherit risks associated with both breeds.

The World Small Animal Veterinary Association states that breeders should select against hereditary disease in pedigree, designer-cross and mixed-breed dogs. Appropriate health screening remains important regardless of whether the parents belong to the same breed. Read the WSAVA health-focused breeding statement.

A responsible breeder should:

• allow you to meet the mother and observe her behaviour;
• provide verifiable health-test results for both parents;
• explain why the particular dogs were paired;
• raise puppies in a clean, stimulating environment;
• begin appropriate socialisation;
• avoid exaggerated body shapes;
• answer questions openly;
• provide veterinary and vaccination records; and
• be willing to take the dog back if the placement fails.

A DNA breed-identification test is not a substitute for appropriate health screening.

Adopting a Jack Russell Mix From a Rescue

Rescue organisations often have Jack Russell-type dogs and terrier mixes looking for homes. The dog’s exact parentage may be unknown, but its foster carers may provide valuable information about its actual personality and behaviour.

Ask the rescue about:

• behaviour around adults and children;
• response to dogs, cats and smaller animals;
• separation-related behaviour;
• housetraining;
• guarding of food or toys;
• reaction to handling;
• known medical conditions;
• exercise requirements; and
• ability to settle indoors.

An adult rescue dog can sometimes be easier to match to a household because its approximate size, coat and established behaviour are already visible.

Preparing Your Home for a Jack Russell Cross

Before bringing the dog home, prepare:

• a secure harness and lead;
• identification tag and microchip registration;
• a comfortable sleeping area;
• suitable food recommended for its life stage;
• food and water bowls;
• safe chew items;
• interactive feeding toys;
• baby gates where necessary;
• a secure garden with checked fencing; and
• an appointment with your veterinarian.

Many Jack Russell mixes can jump, climb or dig. Do not assume that a short fence will contain a small dog.

Frequently Asked Questions

What is the most popular Jack Russell cross?

There is no authoritative worldwide ranking of Jack Russell crosses. The Jack Chi, Jug, Jackapoo, Jackabee and Jackshund are among the names frequently used for these mixes, but popularity varies by country and over time.

What is the calmest Jack Russell mix?

No particular cross is guaranteed to be calm. Temperament is influenced by genetics, early development, socialisation, health, training and daily environment. Meeting an adult dog through a reputable rescue may offer more behavioural predictability than choosing a young puppy.

Are Jack Russell mixes easy to train?

Many are intelligent and capable learners, but they may also be independent, easily distracted or strongly motivated by movement and scents. Short, positive training sessions usually work better than punishment or repetitive drilling.

Can a Jack Russell mix live in an apartment?

Some can, provided their exercise, toilet, training and enrichment needs are met. Barking, prey drive and the ability to settle indoors may be more important than body size.

Are Jack Russell crosses good with cats?

Some live peacefully with cats, while others have a strong desire to chase them. Early socialisation may help, but it cannot guarantee compatibility. Introductions must be gradual and supervised, and the cat should always have safe escape spaces.

How long do Jack Russell mixes live?

Lifespan varies according to size, genetics, body shape, diet, preventive healthcare and individual medical conditions. It is more responsible to discuss the particular dog’s likely health with a veterinarian than to rely on one lifespan estimate for every cross.

Do Jack Russell mixes need much exercise?

Most need daily physical exercise and mental stimulation. However, the amount should be adjusted for the dog’s age, health, body structure and inherited traits. Puppies and dogs with breathing or spinal problems require special consideration.

Can I predict what a Jack Russell cross puppy will look like?

Not precisely. Puppies can inherit different combinations of size, coat, colour, ear shape, leg length and facial structure—even within one litter.

Final Thoughts

Jack Russell Terrier crosses can be intelligent, affectionate and entertaining companions. They can also be energetic, vocal, determined and challenging when their needs are underestimated.

A crossbreed name should be treated as a clue about possible ancestry—not a guarantee of appearance, temperament or health.

Whether you choose a Jack Chi, Jackapoo, Jackabee or another Jack Russell mix, focus on the individual dog. Consider its behaviour, health, energy level and compatibility with your household before making a long-term commitment.

When buying a puppy, insist on appropriate health screening for both parents. When adopting, work with a rescue that has assessed the dog carefully and is honest about its needs.
