  • proin
    Our Older female requires this medication 3 x day. This is the absolutely best price I have found and they send it automatically so that I never run out. I am very happy with their service. by on 10/10/2020
  • Dog Prescription
    This was one of the only places I could find my dog's medication (Proin) & at a fraction of the cost of what my vet charges! by on 09/16/2020
  • Works Great
    My female Dog has a leaky bladder and this medicene works so well that if I skip one day of giving it to her she immediately leaks. Also if I stop giving her Proin for one does.. she will leak. IT WORKS by on 09/14/2020
  • Works great!
    This is working so well for our 2-year-old rescue giant schnauzer that was having issues with "leaking" - no more messes to clean up and everyone is happier! by on 08/09/2020
  • No complaints!
    We have been ordering Proin for several years for our female german shepherd. She has been incontinent her whole life. We have gotten it from a few sources (vets, other websites) but PetCareRX has the better price and the auto ship option! Now I don’t have to think about ordering in time on top of all the other things I have to do. The medication is carefully packaged and none have been broken yet! And it does a good job of reducing dribbling in our dog! by on 08/04/2020
  • Works great for my dog
    This medicine is very effective for my dog. My 5yr old chocolate lab mix was fixed and after the surgery she had a problem with leaking. Proin worked almost immediately and makes my life a little easier as well by on 06/17/2020
