Dosage of Furosemide for CHF in Dogs

Furosemide dosage for dogs with heart failure

The correct Furosemide dosage for dogs with heart failure can be discussed with your veterinarian. If you are giving your dog supplements that act as diuretics for cats and dogs, you should tell your veterinarian.

While most pets may benefit from taking Furosemide orally, there are other ways to give it. For example, if your veterinarian determines that your dog requires it, they may give the medicine intravenously. They may give up to 4 mg/kg every two hours via intravenous fluids.

If you're giving your dog Furosemide at home, some dogs may be given 1 to 2 mg/kg every 12 hours. Your veterinarian may increase this dosage. Dogs can be given up to 6 mg/kg orally every eight hours.
