Just like some people love mushrooms and other people hate mushrooms- dogs are the same with treats and food. My dog LOVES these and thinks they are treats. But once you get passed the taste test, do they actually help is the real question and what people should be reviewing. In my opinion, yes- very much so. I’ve had my 10 year old German Shep on these for several months. The vet and groomers say his coat and skin look great, even in the cold dry weather, which is a great plus I wasn’t expecting. He has less trouble getting up from sit or laying down. His right side back hip used to get tired and he would limp a little after waking up or after a long walk or fun play session. I’ve noticed he doesn’t do it as much anymore since I’ve been giving this to him. It is an over time build up, but this is common for giving glucosamine pills and it’s best to start earlier in mature dogs to help as they get older to ease discomfort etc. It’s preventive care, it will not fix or restore your dog back 100%, that’s medically impossible.
