My husband and I have a 9 year old large breed hound who hurt his ACL about a year and a half ago running on our property. He’s a rescue who’d been abused before we got him as a puppy so the vet advised us against surgery. Especially because they believe what could’ve been slight hip and joint pain before the injury, now with the injury on top of that, his hip and knee on the right side had become a big big problem. We tried pain meds, and about a year later, we would have good days and really bad days. Sometimes his leg would be in so much discomfort he’d only be able to run with 3 paws on the ground. Or our 1 year old puppy would only be able to play with him for about 5 minutes before his leg would start to hurt and he would be done. His quality of life was definitely starting to be a worry. BUT I picked this up on a “I will literally try anything whim” and WOW. I honestly can’t tell you the last time we had a bad day. I started using this about 4 months ago(ish) and we were just talking last night about what a difference we see! He seems so much more comfortable and I am so so thankful.
