This is a miracle drug that pretty much instantly changed both my (older) dogs' lives. Every vet tech I've spoken to (it's a monthly injection) agrees it is amazing.
He also loves the cold, and he's always more active in the winter anyway. I would say he's close to the level he was last winter instead of slightly declined. That's great, but not miraculous.
We'll stick with the regimen and see if he continues to improve. I'll upgrade my judgement if he starts climbing stairs again.
36 hours later, the limping stops and the dog wants to walk further than he has in years. We take him to doggy daycare once a week since his housemate passed, and daycare staff commented on how he was like a new dog. Not every day is a great day, but most of them are.
My girl has had shoulder arthritis for years and walked with a limp. We had her on daily pain medication and we tried multiple kinds because they weren't very effective. It always was a chore because she hated the pills and would literally eat around them in placed inside a treat (she wouldn't even take the flavored ones). She was in pain and would basically just lay down all day.
Now? No limping anymore. No pills. She isn't scared to go up and down the stairs. Jumping on and off the couch without missing going up or being scared to hop down. Running around with my other dog.
It's really been night and day.
We thought we were going to have to say goodbye to our girl back in February this year. Her arthritis was so bad, she'd stopped using the litter and was... Backed up, let's just say.
But she's currently curled up right next to me, and generally acts like she used to a couple years ago. You can tell her legs are weaker than they were, but the pain doesn't bother her anymore.
Miracle is a pretty reasonable word, yeah.
He isn't back to being a kitten, you should have appropriate expectations, but he wasn't able to jump on or off the couch before, now he can. He is walking around more than he used to, before he would spent most of the day in his box. The effect of getting him more exercise is compounding his good health.
If you have an older cat/dog you should definitely talk to your vet about it.
The other comments imply the same; it will depend a bit on the dog's condition. That being said, I still stand by my miracle drug assertion. And seemingly side-effect free.
