13 Most Common Diseases Found In Jack Russell Terriers

Cardiomyopathy is a weakening of the heart muscle that often involves a thickened heart but can also involve dilation of the chambers (or stiffening of the muscle).

Unfortunately, there are rarely any early signs of cardiomyopathy, and you are more likely to notice it in your Jack Russell once the disease has become more advanced.

Since the complications include pleural effusion and pulmonary edema (i.e. water in the chest cavity or in the lungs), you may notice your dog breathing more quickly or in a way that seems labored.

You should also be wary of cardiomyopathy if you spot reduced tolerance to exercise.
