CHF supplements for a dog can help with the symptoms of congestive heart failure. You will often find that your dog is less tired and has more energy. They may also wheeze less.
CHF supplements
 for a cat can help them to feel better. Despite that, it doesn't mean 
that you can stop giving everything that your vet has prescribed. If you
 stop giving the medication, your cat's health may seem to suddenly take
 a turn for the worse.
Like natural diuretics for dogs, Furosemide can help to alleviate wheezing and coughing in dogs and cats, that is due to heart disease.
