Sudden concerning symptoms in dog w/ CHF starting furosemide

Hello, I'm glad you reached out. It sounds like your dog has recently started furosemide for congestive heart failure (CHF) and is now showing some symptoms that concern you. This medication is commonly used to help remove excess fluid from the body, but it's important to closely monitor your dog, especially in the early days of starting the treatment.



Some common side effects of furosemide can include increased thirst and urination, as it works by removing excess fluid. You might notice your dog drinking more water and needing to go outside more often, which is expected. However, there are a few signs to watch for that could indicate more serious concerns. If your dog is experiencing vomiting, diarrhea, sudden lethargy, or changes in breathing patterns (such as increased rate or effort), get in touch with a vet immediately.



At home, make sure your pet has plenty of water available and is encouraged to rest. Ensure they're in a comfortable environment and avoid overexertion.



Keep an eye on these symptoms, and if they persist or worsen, or if new symptoms appear, it might be a good idea to book a video consultation with one of our vets at Dial A Vet. They can help you assess the situation and determine the best course of action for your pup's health.
