We have two dogs who grew up together from puppies. They used to LOVE to play and run around but were starting to struggle with age and were not as mobile as they used to be. I just wanted them to have the freedom to run, jump and play like they used to. I was sceptical to try the Hip & Joint treats as I have tried a couple of things in the past, but because they are made into treats I thought the worst that could happen is them having some different treats to try out.After almost 4 weeks I can say the improvement the treats made on them both is significant. It's like they turned the clock back years for them. They are running, jumping and playing much better and seem much happier now.
