13 Most Common Diseases Found In Jack Russell Terriers


Jack Russell Terriers are happy and energetic dogs that delight their owners with their relentless interest in life and play.

The good news is that they are a generally healthy breed, and that Jack Russell breeders do take care to prevent in-breeding (which helps to reduce problematic mutations).

However, as with all dogs, Jack Russell Terriers are particularly susceptible to certain health problems, some of which are more serious than others.

If you want your dog to live a long and happy life, look out for signs of the following.

1. Lens Luxation

Lens luxation is an inherited disease that can strike Jack Russell Terriers. It affects the eye, causing the lens to dislocate in one or both of the eyes.

Sometimes, owners fail to notice the condition in the early stages, when the lens is only partially dislocated. However, once the lens has fully dislocated, it causes the dog pain and the eye typically turns either opaque or reddish in hue.

Lens luxation is especially likely to develop in older age, and blindness can be prevented if treatment is prompt. If you notice changes in your Jack Russell Terrier’s eyes, visit your vet to discuss the possibility of lens problems.

We did move from a beautiful house in Buffalo 1 year ago and now we live in a manufactured home in Florida.… Read more »

Mine too. He is 11 years old. I think this behaviour is normal as they start getting older.
