Jack Russell 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 Russel 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.
To sum up, some of the common health issues to look out for with a Jack Russell include:
- Patellar luxation
- Deafness or hearing loss
Jack Russell Temperament and Behavior
These dogs have a very inquisitive and curious personality. 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.
A 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.
Jack Russell Food and Diet
Adult dogs will typically require between 1.25 and 1.75 cups of dog food each day. Always choose a 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.
Jack Russell 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 are even easier to maintain, but should still be brushed about once a week.
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.
Jack Russell 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.
Jack Russell Exercise
These terriers are very active and energetic dogs. They require frequent exercise to keep them both physically and mentally stimulating. Possible ways to exercise these dogs include going for hikes, taking long walks, playing in the backyard, or playing around with older children.
Jack Russell Puppies
When you bring home a puppy, it will be important to start training your puppy right away. This will help him or her 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 an excellent family dog. 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 dog’s need 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.
