Understanding Heart Failure


Text version of above

If your dog has been diagnosed with congestive heart disease, there is no need to feel down-hearted. With your care and suitable medication from your vet, a better, longer life for your dog is now in prospect. Understanding your dog’s condition will help you to help your dog.

There are two principal causes of heart failure in dogs:

  • Mitral Valve Disease (MVD) and
  • Dilated Cardiomyopathy

 MVD - A problem with your dog's heart valves

 MVD - What are the signs?

Signs of heart disease can initially be quite mild and so may be difficult to pick up. However, as the disease progresses, the symptoms can become more severe. These signs occur because of fluid build up or because the vital organs are not supplied with the blood, and therefore the oxygen, they require. Signs include:

  • Lack of energy/depression
  • Poor appetite
  • Weight loss
  • Laboured breathing
  • Coughing
  • Weakness
  • Fainting
  • Swollen abdomen (ascites).

 MVD - How is it diagnosed?

 DCM - A problem with your dog's heart muscle

 DCM - What are the signs?
