A healthy heart is essential for dogs to live happy, fulfilling lives. Unfortunately, some dogs live with severe heart problems that may require medication. Enalapril is a commonly prescribed medication that can treat such heart conditions, but is it right for your dog?

What is Enalapril?

Enalapril is an angiotensin converting enzyme (ACE) inhibitor, a medication used to treat hypertension (high blood pressure), heart problems and heart failure in dogs.

Is Enalapril safe for dogs?

Enalapril is FDA-approved for veterinary medicine. In some cases, this medication may not be safe for dogs, though, based on their weight, age, any additional medication(s) they take and any present medical conditions they have. It is critical to consult a veterinarian before starting your dog on treatment with any medication, including Enalapril.


Dosage may differ for every dog, so it is essential to ask your veterinarian about personalized dosing advice for your dog.

The FDA states the following as a general dosing guideline:

  • 0.5 to 1mg per kilogram of body weight per day

The FDA also states the use of this drug is not recommended for dogs who are pregnant or nursing.

Side Effects

According to 1-800-PetMeds, your dog may experience side effects from taking Enalapril, including but not limited to:

  • Allergic reactions
  • Breathing problems
  • Changes in urination patterns
  • Appetite change
  • Sleep issues
  • Vomiting
  • Diarrhea

Call your veterinarian immediately if your dog experiences any side effects.

Final Thoughts

Just like with any other medication, you should be aware of potential risk factors Enalapril might pose on your dog. To ensure your dog receives the safest, healthiest treatment available, make sure their veterinarian is up-to-date on their health history and always follow up both during and after treatment with Enalapril.
