Jack Russell

Jack Russells, also known as Jack Russell Terriers, are highly active, intelligent, and inquisitive dogs. They were bred to assist with fox hunting and are very happy when they are given a job to help their owners. They can make a great family dog for families with older children, but they will need regular exercise and mental stimulation to prevent them from becoming destructive. In most cases, a Jack Russell will do best with an experienced owner who has the necessary time to devote to training and caring for this breed.

Owning a Jack Russell: 3 Pros and Cons

Jack Russell Origins

Jack Russells originated in England in the early 19th century. This dog has a broad genetic makeup as a result of being bred strictly for hunting, and they can be traced back to the now-extinct English white terrier.

The breed takes its name from the Reverend John Russell, who was a hunting enthusiast and bred one of the finest strains of terriers in Devonshire, England, in the late 1800s. Jack Russells were characterized by the following traits:

• White color so they wouldn’t be confused with foxes.
• Hard and thick fur protects their skin.
• A brave hunter spirit.

Size and Weight

Jack Russells are a small breed. Both males and females are around the same size and typically weigh between 9 and 15 pounds and are between 10 and 12 inches tall. When puppies are three months old, they typically weigh between 6 and 8 pounds. By the time the puppies are six months old, they’ll weigh between 9 and 11 pounds. The dog will finish growing when it is about 12 months old.

Common Health Issues

Overall, these terriers are a healthy dog breed. However, there are still a few health concerns that are more common in this breed that you’ll want to be on the lookout for.

One potential concern with these dogs is patellar luxation. This problem occurs when the three bones around the knee, the patella (kneecap), femur, and tibia, are not aligned correctly. This can be very painful for a Jack Russell and may require surgery to correct.

Glaucoma is another health concern for them. Glaucoma causes the pressure in the eye to rise, which can cause damage to the optic nerve. Eventually, this can cause a Jack Russell Terrier to become blind.

These dogs also have a higher rate of deafness than some other dog breeds. Deafness is a hereditary issue and cannot be reversed. Some may experience complete deafness, while others may only experience a partial loss of hearing.

Temperament and Behavior

These dogs have an inquisitive personality. They will quickly find new insects in your garden, so be careful that they do not eat one of the newly hatched cicadas! They are also highly intelligent dogs with a high need for exercise. If they don’t receive sufficient exercise and mental stimulation, however, Jack Russells may display destructive behaviors when left alone.

Jack Russell’s traits can also make them a good family dog. They are very playful and can also be very affectionate with the members of their family.

How to Take Care of a Jack Russell

These dogs will require a unique care plan from other dogs. Keep their temperament, potential health concerns, exercise needs, nutritional needs, and more in mind as you prepare to care for your dog.

Feeding

Adult dogs will typically require between 1.25 and 1.75 cups of dog food each day. Always choose high-quality and nutritious dog food for your dog and consult with your veterinarian if you need help choosing the best option. Different factors can contribute to the exact amount of food your dog will need. These include his weight, activity level, age, and health concerns. Again, your dog’s veterinarian is a good source of information if you are unsure how much he should eat. It is typically recommended to split the total daily amount of food for a Jack Russell Terrier into two smaller meals.

Since a puppy has a smaller stomach, it is important to feed them smaller, more frequent meals. Younger puppies will need about three or four meals each day. Once the dog is between five and six months old, two meals a day should be sufficient. Since a puppy needs a higher ratio of protein and calories for each pound than an adult, most will eat the same quantity of food when they are a puppy as when they are fully grown.

Maintenance and Grooming

These dogs require less maintenance and grooming than other dog breeds. They may have either a smooth, broken, or rough coat. Jack Russells with a smooth coat will need to be brushed using a soft brush about once a week. Rough and broken coats, while they don’t need extra grooming, should still be brushed about once a week.

Types Of Coats

Coats are divided into three different categories:

• Smooth Coat
• Rough Coat
• Broken Coat

Smooth Coats do not have trace hair on the face, head, legs, or body. A rough coat has excess hair covering its entire body. A broken coat has a combination of both smooth and rough coats.

In addition to brushing your terrier, it is also important to brush their teeth a few times a week, trim their nails to prevent them from getting too long or painful, and check their ears to remove any excess wax, dirt, or other debris.

Training

Jack Russells are intelligent dogs who are eager to please their owners. These traits can make them easier to train than some other dog breeds. However, because of their intelligence, they can also get bored quite easily, which can make training them a greater challenge. For this reason, be sure to keep the training session exciting and varied. These dogs do best with positive reinforcement and won’t respond as well to punishment-based training methods.

Exercise

These terriers are very active and energetic dogs. They require frequent exercise to keep them both physically and mentally stimulated. Possible ways to exercise these dogs include going for hikes, taking long walks, playing in the backyard, or playing around with older children.

Puppies

When you bring home a puppy, it will be important to start training your puppy right away. This will help it learn expectations as well as the appropriate way to interact in different situations and around other dogs and people.

Before you bring your dog home, you’ll want to make sure that your home is puppy-proof. Move anything that you wouldn’t want to see destroyed by a puppy, or that could be potentially harmful to your new dog. Also, make sure you are prepared with a bed, a collar and leash, food, treats, and other supplies before bringing home a Jack Russell.

Jack Russells and Children

With proper training and care, these terriers can make excellent family dogs. They are very playful, loving, and devoted to the members of their family. However, these dogs can be overly active and might be a bit much for babies or toddlers.

It will be important to make sure these dogs’ needs for exercise and stimulation are met to prevent them from getting overly active. Even though they are good with children, it is always important to supervise children around them and other dog breeds. This is especially true for younger children who may not yet know how to interact appropriately with a dog.

Dogs similar to Jack Russell

Three dog breeds similar to these dogs are Boston Terriers, Basenjis, and Norfolk Terriers.

• Boston Terriers: Boston Terriers and Jack Russells are both small dogs that are very affectionate and can easily adapt to new situations. One difference between these two breeds lies in their history. While Jack Russells were bred to be hunting dogs, Boston Terriers were bred to be companion dogs.
• Basenjis: Basenjis and Jack Russells are both high-energy dogs who need a lot of exercise. Basenjis are a bit larger, with an average male weight of 24 pounds compared to the 14.5 pounds that an average Jack Russell weighs.
• Norfolk Terriers: Norfolk Terriers and Jack Russells can both be very playful. Both breeds are also more vocal than many other dog breeds. Jack Russells have higher intelligence than Norfolk Terriers and are also much more likely to try to chase and catch something they perceive as prey when compared to a Norfolk Terrier.

Famous Jack Russells

These terriers are a very popular breed, so it should come as no surprise that there are quite a few famous Jack Russells:

• Uggie was a famous dog who was in movies such as ‘Water for Elephants’ in 2011 and ‘The Artist’ in 2011.
• Bluebell is a Jack Russell Terrier rescued by Camilla, Queen Consort; her other Jack Russell, Beth, passed away in late 2024 and was replaced by a new puppy in early 2025.
