Try this instead of Ark Happy Joints

I was considering buying these treats for my two dogs that have Hip Dysplasia, but too many bad or so-so reviews. For those who did not like the treats, thought they were too expensive, or their dogs did not like them. You may want to try Dasaquin supplemental treats. They were recommended to me by my Vet.

Happy Joints

My nearly 14 year old shepard mix seems to have a little more energy and ease of movement since I started him on these. If it were't for his partial blindness and deafness, he's like a new dog.

Review of Product

The product is fine but you only get ten pieces for $34. Way too expensive for what you get.

Great concept, not so great appeal

My dog has never really found a treat he does not like, however he is very skeptical every time I try to give him these. I think the texture is what gets him. They are a great concept and really beneficial but he does not enjoy them as much as other options. Like a child, he doesn’t understand when I tell him they are really good for him! I am satisfied but he is not.

Best Joint supplement for Dogs

I used to buy the smaller ones but decided to try these since I would only have to give my dog 1 vs 3. He wouldn't eat them unless I break them into smaller pieces and then he eats them just fine. I may go back to the smaller treats, but I will def stick with this product. I have been giving them to my dog for years and he's getting older but is showing NO signs of slowing down or joint issues and he will be 11 in 2 months. Best Joint supplement in treat form! If your dog doesn't like the taste then try the smaller treats.

Smells awful and the dog runs away from it.

I previously bought what I thought was this gray Muzzle product in a small wafer chew, which my senior Staffy loved. This purchase happy joints maximum chews smell awful and he runs away as soon as he sees the bag. This is a big old dog that loves any food but not these supplements. I tried to hide it in something he loves but he spits it out. I would give this product ZERO and a wasted money as I purchased 2 big bags.

Improvement in my dog’s health

My 10 year old large dog was having mobility problems. He has been on Old Dogs! Happy Joints! for a few months now and I notice a big improvement. They are stinky, but he eats them when I add them to his morning meal. He is not a picky eater which helps. They seem to have boosted his health enough that he is playing again. He will continue on these.

My eat everything pup will not eat these

My headline says it all. I have to hide them in wet food to get her to eat them and sometimes that doesn’t even work. I like the idea of them just need to be better tasting.

bad smell like fish

My 9 year old Great Dane turned up his nose at these fishy smelling treats. I was hopeful to help find a glucosamine tablet to help with some back leg issues. Also my bag was hard as a rock nuggets, I thought they were supposed to be soft chews for elderly dogs. Pass on this brand.
