I took Marty to the vet as I notice he was having trouble lifting his leg to pee and started needing help to get in the car. The vet said his knees pop out both ways and he could need surgery. I was given Meloxicam to help with the pain and the side effects looks awful. I have never use this drug on a pet and wonder if anyone has and how helpful it was for their pet. Marty is only 3 yo but I was told trick knees is common in small dogs . The worst part about the drug it Marty should have a meal before getting the pill and the drug can made a dog loss their appetite.
