I'm a big fan of CBD for dogs. When my boxer Lexi was around 10 years old she started having trouble moving around and her quality of life was diminishing. We tried all kinds of pills and therapies, but it wasn't until we tried CBD infused treats that we saw real improvement. After a couple of weeks on the treats she was like a different dog. She was back to her old self, running around and enjoying life again.
The treats were expensive, but worth it for us. The improvement was dramatic and stayed that way, and she lived to 12 years old. I recommend them to any of my neighbors who have dogs with mobility issues. The brand we used was Ellevet which was the only brand available to us at the time.
We of course discussed them with our vet, and she didn't feel strongly one way or the other about them.
I can't vouch for their formulation or quality now because I don't know if they've changed anything, but at the time they were amazing and I would 100% use them again in the future.
