Benazepril is a generic medication that belongs to a class of drugs known as angiotensin-converting enzyme (ACE) inhibitors. Veterinarians prescribe benazepril to lower blood pressure levels in dogs.

Function
-
Angiotensin II is a substance found in the bloodstream that causes dogs' blood vessels to constrict, causing elevations in blood pressure. Benazepril functions by preventing the production of angiotensin II, which in turn lowers blood pressure levels.
Benefits
-
In addition to lowering blood pressure levels, benazepril also helps prevent heart failure and improves dogs' ability to withstand exercise, according to the Merck Veterinary Manual.
Dosage
-
Veterinarians typically prescribe 0.12 mg to 0.25 mg of benazepril for each pound a dog weighs for use once or twice a day, explains PetPlace.com. Once a dog begins treatment with benazepril, it will likely need the drug for the rest of its life.
Risks
-
Nausea, appetite loss, diarrhea and low blood pressure are possible side effects of Benazepril, notes the Veterinary Partner website. Some dogs experience elevations in blood potassium levels while taking Benazepril, especially when also taking diuretic drugs for hypertension like spironolactone.
Considerations
-
A pregnant or nursing dog, or one that has impaired kidney functioning, should not take benazepril, Veterinary Partner states. The human form of benazepril could be harmful to dogs.
