Thanks everyone. Luckily most of our house is one floor and there is no need for him to go up the steps which we have gated of anyway because Dixie has learned how to climb them and they are slippery wood so don't want that happening. My dad built a ramp on our deck when we moved here for Callie and the dogs prefer to use that to the steps so that's good too. I know I'm like super jaded because of how bad Callie's were so I was freaking out. The biggest issues with a joint supplement is he is soooooo picky and is hard enough to get heartgard and nexgard in him and a powder would never work because he picks at food and doesn't eat a lot at one time so we may just wait and see how things go. Him being food picking a not overeating is probably good in this case so he wont get overweight and he is extremely active. I'm sure I will be at the vet again soon and can talk to her more about it because my mom had taken the call when I was tied up with the puppy. Callie's orthopedic surgeon recommended Dosaquin at the time but that was many years ago and I doubt he will take it. Again thanks everyone
