“We bought Previcox because it worked better than any other nonsteroidal anti inflammitory that we have used for our 3 1/2 yr old yellow lab with severe elbow dysplasia. It was also the best price we could find anwhere, We have 3 dogs and all have medical issues. We spend around $300 per month on their meds. So, you can see why we have to shop around for best prices with safe reputations and good quality. Thank you, Allivet!”
