Our Puppy needs a double hip replacement and the cost of the medication for pair through the local vet was very expensive. I started looking on line for a cheaper way to get the medication. I found the same medication at a third of the price at the vets. Never having ordered pet medications through the mail before I was a little concerned about what I was really going to get. Well I got he package and it is identical to what the vet sold me. Very pleased as this puppy may need to be on this medication daily for over six months after surgery.
