What does a diagnosis of heart disease mean?

Staying informed and knowing what signs to look for is important because early diagnosis and treatment of heart disease may help significantly prolong and improve your dog's life.1,2,3

In the early stages of heart disease, your dog may show no visible signs of being unwell; however, as time progresses, so can their condition.

Benefits of early diagnosis

The outlook for dogs with heart disease has improved significantly in recent years, with emphasis shifting to early treatment for optimal benefits.

Scientific research shows that effective treatment started early, before heart disease signs become apparent (Stage B2 heart disease*), can help ensure that dogs continue to enjoy a good quality of life and can extend their length of life.3

*For more information on the stages of heart disease see Stages of heart disease

There are tests your vet can perform to identify your dog’s stage of heart disease, that will help them plan the right course of action, for example:

  • • listening to the heart through a stethoscope
  • • assessing the heart, lungs, and major blood vessels on an x-ray
  • • assessing the electrical rhythm of the heart through an electrocardiogram
  • • watching the heart at work on an ultrasound

The benefits of early diagnosis and treatment, even before the onset of signs, makes regular heart checks in dogs more important than ever before.
