    No problem getting the puppies to eat it which was a problem with some other glucosamine product s I've tried.

    Nasty smelling but they must taste good. My yellow lab likes them. She hasn't been on them long enough to tell if they're doing her any good.

  • Still waiting to see the full effect's

    My puppy loves the taste ( she's a food lover, so there's nothing she doesn't like.) I'll get back to this review after she's been on it for a few months.

  • Glycoflex > Cosequin

    By on

    Yep, y'all read that right. I have an 8 year old ACD with two partially torn ligaments and two bad hips (She's a rescue before anyone tries to jump on the breeder train) We've been giving her cosequin for years and while it helps, she would still get stiff. So I picked this up on a whim on sale and I'm sad I didn't buy SEVERAL bags. This + The American Journey dog food (that also has glucosamine in it) has been life changing for my old gal. Running is fun again and she's no longer stiff and sore like she used to be! Definitely recommend this!

  • My dog loves them

    By on

    Obviously no results as I have a dog with no joint issues. However he is a large young dog who does agility so hoping this prevents issues later on. He loves the flavor!

    It takes a couple months to see the difference, but it does seem to work.

  • Wonderful product

    By on

    Have used this product years ago for a dog with arthritis and it worked wonderfully. Now we have a dog with joint issues and this product has once again aided in giving relief when the weather is bad and effects our boy more. Would recommend it to anyone. Use as directed and it will do just what it is suppose to.

  • Great for joint health!

    By on Top 25 Contributor

    I give both my 2 year old and 7 year old dogs this joint supplement. They are active and aging so I want to give them a supplement that will protect their joints now and in the future. As a bonus they both love the taste!!

  • This is a mainstay at our house!

    By on

    I had my Dane on a variation of this product (Stage 3), and I am convinced it gave us a few extra years with him!! I will use this product on every dog I mother! I will never be without it, as long as I can help it! This will become an Autoship item! I only wish I knew about this item when I had my Dane, because their prices are SO much better!!
