13 Most Common Diseases Found In Jack Russell Terriers

However, it is more common for an unusual heart sound (i.e. a murmur) to be detected during a routine appointment, or to notice that your dog may seem to be weaker than average.

It is extremely important to be aware of patent ductus arteriosus in early life, as timely diagnosis by a vet can lead to highly successful surgery, which becomes less effective as the dog gets older.

My Jack Russell is doing the same exact thing.😢😢 I have to take him into the vet. He’s been lazy lately and in his cage. The littlest things startle him
