What should you feed a heart worm positive dog?

A heartworm positive dog requires a balanced diet just like any other dog and unless the parasites have lead to changes in heart function and congestive heart failure, there is no need to change from a balanced adult dog food. If congestive heart failure secondary to heartworm infection is present then a diet designed specifically for Heart disease in dogs is recommended. There are different veterinary diets on the market recommended for this condition and pet owners should consult their vet to find an appropriate diet.
