I have relied on California Pet Pharmacy (CPP) for several years to ensure our two dogs' total health. While I had previously tried a few different online pharmacies, I have always found CPP to be THE best source, in terms of quality, ease of ordering & delivery & affordability. I get both dogs' Heartgard Plus & Comfortis from them, as well as Vetmedin & Enalapril for our one dog who has a heart issue. I have found CPP to provide extremely efficient & timely service. Now that they have added online account features, i. E., you create your account, which includes your pets' names, medical conditions & medications needed, along with veterinarian's information, it is an easy, seamless process to order & receive needed medications. I recommend CPP wholeheartedly!
