Frequently asked questions

What are canine diuretics used for?

Some conditions like congestive heart failure, lung fluid retention, and kidney diseases can cause a dangerous build up of fluid in your dog’s body. In these cases, it’s important to relieve the excess fluid. Canine diuretics are a medication to help do so. They help get rid of excess fluid by increasing urine production and alleviating symptoms related to fluid buildup.

What are the most commonly prescribed diuretics for dogs?

The most commonly prescribed dog diuretic for the relief of acute fluid buildup is a medication known as Furosemide. This is a loop diuretic that causes the kidneys to produce more urine. At Dutch, we carry several different types of Furosemide. Furosemide Tablets (Rx) can be great for dogs who tolerate pills, while Furosemide Oral Solution (Rx) is a good, liquid alternative that some may find easier to administer. We also carry Salix Tablets (Rx)

Talk to your vet about which of these medications may be best for your dog’s needs. Dutch members get unlimited access to licensed veterinarians to ask questions and address health concerns. They also get guaranteed low Rx prices and free shipping on all orders from Dutch’s online pet pharmacy.

Do diuretics help dogs with congestive heart failure?

Yes, diuretics for dogs are one of the primary treatments for congestive heart failure. When a dog is in congestive heart failure, its heart has a difficult time pumping, which allows dangerous levels of fluid to build up in the lungs and the abdomen. Not only can this cause discomfort, but it can also lead to difficulty breathing. Canine diuretics help dogs flush this liquid out via their urine. 

If you think your dog may be showing signs of congestive heart failure, talk to a vet immediately. They can diagnose the issue and help prescribe a treatment to alleviate your dog’s discomfort.

What are the side effects of furosemide in dogs​?

Most common side effects of furosemide diuretic for dogs are increased thirst and gastrointestinal upset, like vomiting or diarrhea. Less common but dangerous side effects also include: 

  • Dehydration 
  • Electrolyte imbalance 
  • Weakness
  • Lethargy 
  • Kidney issues 
  • Hearing loss 

If you’re concerned about the side effects your dog may be experiencing from furosemide, talk to your vet. They can help determine whether they should continue taking the medication or switch to another treatment.

How are canine diuretics administered?

Canine diuretics can come in several different forms, including tablets and liquid medications. In some cases, dog diuretics may also be directly injected. Talk to your vet about the best formulation for your pet’s needs. They can determine the dosage, frequency, and other important factors. 

It’s always important to provide your dog plenty of fresh drinking water when they’re taking canine diuretics. Their increased urination can lead to dehydration if they don’t have enough water to replenish their fluids.
