The signs of heart disease are:

• Coughing – especially when your pet wakes up from sleep
• Intolerance to exercise
• A fatter looking abdomen
• Difficulty breathing
• Collapse or fainting

If your dog is exhibiting any of these clinical signs we recommend that you bring your pet in to see a vet. The vet may ask you questions like:

• Is your pet breathing faster than normal?
• Is your pet eating and drinking/urinating normally?

Breeds which are more prone to heart disease are Cavalier King Charles Spaniels and Dobermans. Female dogs are more prone to congenital heart disease.
