I have a 10yr old Irish Wolfhound mix-- big dog that began experiencing stiffness in the mornings and was frequently limping after long running sessions (which he absolutely needs because he is high energy) I bought this about 3 weeks ago after receiving a recommendation from a horse trainer/holistic healer friend who highly suggested MSM for everything from upset tummy to arthritis. I followed the recommended dosage of 6tbsp (double dose) for his weight but I only gave that much for the first 3 days, and already saw improvement on day 2. I only give him 2-3tbsp for day (I think the package recommends 3 for his weight) and I have quickly experienced my dog being more ready to get up and play in the morning, more able to keep his feet under him (for a year he had an issue of one of his feet occasionally slipping out from under him on hard surfaces), being more playful and ready for games of fetch, shorter recovery time after a walk. Oh, and that painful limp he had from his left shoulder disappeared completely after we have our long runs twice a week. As a side note/bonus, my dog has environmental allergies and used to be absolutely miserable for the past 8 years scratching the hair off his muzzle and constantly having inflamed ears. I used to take him to the vet for steroid injections because allergy pills didn't work. I was completely surprised when I realized my dog has not been scratching/groaning since I began giving this supplement to him. Wow wow wow! I never expected this to help his allergies but I am sooo happy to see he is way more comfortable in all of his life now. I am really amazed by the effectiveness of this product. My dog LOVES the taste and we have come across 0 issues with it. I've also poured it into a little water if I noticed he wasn't drinking enough on really hot days and that encouraged him to stay hydrated. I've already recommended this product to my friends and family (we are going to start our little Sealyham terrier on this, he's a rescue who broke his hip long before we got him and some days he can barely move from the stiffness) and I just wanted to share here. If you're considering this product, go for it. I love it and I am so thrilled with the quick results keeping my dog happy and comfortable.

Thought I would give this a try as was on sale to save money. I now know why. My old heeler would not get near it like teh other liquid brand I usuaully buy. Wasted money. I read the ingredients after he would not take it. Corn syrup and a bunch of other chemical junk in there. No wonder he hated it. Going back to the other.
