Rated 5 out of 5 by 27 reviewers.
Rated 5 out of 5by Top Notch!My dog has congestive heart failure and needs meds 2x per day. Sometimes the fact that I need to re-order a Rx sneaks up on me. PetCare Rx comes through with excellence in timeliness, cost and service. I would recommend them to anyone. The Enalapril is consistently effective for his condition. I would also recommend Enalapril. 09/05/2018
Rated 5 out of 5by pricing and availabilityGreat help to my dog, but as it is also used by humans, it is available at local pharmacies who do not accept PetCarerx membership. As a result, they charge out-of-pocket, which is five times the PetCarerx membership fee. I will continue to use PetCarerx. 07/11/2018
Rated 5 out of 5by They're keeping Me AliveI'm a 13 year old King Charles with serious congestive heart issues.My vet got me on these pills ( and some others) over a year ago saying it would help for a "few months" but not much else can be done. Well,it's been 14 months and I now go by the name Charlie the Wonder Dog at the Vet's office. 05/10/2018
Rated 5 out of 5by quick service!This medication is a lot cheaper than it is from my veterinarian, and the shipment arrived quickly without any problems. 01/29/2018
Rated 5 out of 5by Product Enalapril is a LIfe Saver for my DogThe vet prescribed this for my 9 year old maltese, Prince. He was having problems after his twin sister died in Oct 2017 from Cushing Disease. Both dogs were diabetic and had to take insulin. Prince really misses his sister and has anxiety or panic attacks when we leave the house. He would be at the door and his mouth would be wet and his paws. He would be breathing heavy too. The vet recommended this med and he has been taken it along with Vetmedin and Salix. Probably because he is older and his heart is weakening. This med is great and no side effects. Prince doesn't like to take any pills. I tried different foods and sometimes he waits and holds the pill in his mouth and goes into another room and spites it out. He is something else. I am greatful that there is meds for our pets to help them so we can enjoy them longer. 01/14/2018

Rated 5 out of 5by This product works!We have been giving our dog Enalapril for several years. We recently found out that we can purchase it through PetCare RX for a fraction of what we were paying the vet. This has helped us immensely 03/28/2016

Rated 5 out of 5by Great productThis heart medicine along with Lasix works great for my chihuahua with CHF. He is doing well and 12 years old. 01/01/2016
Rated 5 out of 5by Product is as statedAt the latest vet visit, Max's health is in good standing. So, apparently medication is working just fine. 02/18/2015
Rated 4 out of 5by Rx seems effectiveWe are using this as our chocolate lab (10.5 yrs) was found to have only one kidney. It was found after blood & urine tests were elevated. It is being used to 'maintain' the levels per specialists affiiliated with UC Davis. So far it seems to be working as desired. 12/09/2014
