We adopted a Pyr/Rottweiler/Collie mix from a kill shelter down south in January 2020. He was about 2.5 months old. Not sure as he was abandoned on the side of the road in a box.

He's now 11-12 months. And for the past week or so, he is having trouble getting up from a laying position, trouble up and down the stairs, and occasionally moans in pain for no apparent reason.

Today, I took him to the vet and they did x-rays and showed hip dysplasia on both sides. One is worse than the other. They gave pain/inflammation pills (Carprofen 75mg). We gave him a pill about 5pm. By 6pm, he was moving well, and seemed happier. The vet also gave him a chewable joint supplement.

I know he can't be on pain pills long term, so what would you recommend? TIA
