Health

Jack Russell Terriers are a generally healthy breed of dog but are more prone to certain conditions. Obviously, not all Jack Russell Terriers will face the below conditions but they are worth you being aware of.

Deafness – While Jack Russell Terriers can sometimes experience selective hearing, especially when they’re chasing prey the breed does have a higher proportion of dogs that will experience deafness.

Glaucoma – Similar to the human condition, glaucoma is where there is abnormally high pressure in the eye, which causes damage to the optic nerve. This damage to the optic nerve can result in your dog going blind.

Lens Luxation – This condition is where the ligaments holding the lens of the eye in place deteriorates. In extreme cases it may require the eye to be surgically removed but if identified early enough it can be treated through medicine or surgery.

Legg-Calve-Perthes Disease – This disease is where there is a deformity in the hip joint and the ball of the socket causes unusually high amounts of wearing to the joint and can result in arthritis. It is a condition that is unfortunately pretty common in small breeds of dogs. Surgery is required to resolve this and will likely mean your dog will take some time to be able to walk easily again.

Patellar Luxation – Another condition that is common for small dogs, Patella Luxation is a condition that can result in Jack Russell Terriers having an unusual gait, this can look like they’re skipping. This is caused by the bones in their leg not lining up properly. This is a condition that they are born with but may not be noticeable until later in life. This can result in arthritis in the leg. 

Older age

One of the main afflictions that older Jack Russell Terriers have is poor eyesight. This is why you will regularly find when visiting someone with an elderly Jack Russell Terrier one of the first things they will say is to be careful around them as they can’t see very well. 

As Jack Russell Terriers are prone to deafness this can also get more pronounced as they get older. Thankfully as they get older they slow down so are less likely to be running off and needing to be called back but their hearing can start to go before when it will be hard to keep up with them.

As they get older they can also find it harder to jump up. Thankfully as Jack Russell Terriers are smaller dogs it can be picked up if you want to bring them into bed with them but it will mean they won’t be able to jump onto seats to join you like they could do when they were younger.

Allergies

Jack Russell Terriers are prone to allergies, both to foods and other potential irritants. Usually the allergies will show as rashes, spots on the skin or hair loss.

If your dog starts to show symptoms of allergies it would be worth taking your dog to your vet to get them properly tested.
