    GSD Pups Love Them

    By on

    We have two GSD pups (3 months and 8 months) and they have both been on these since we brought them home. These resemble a chewy treat, and both pups absolutely love them! Our younger puppy is usually very picky with treats, but I just break these in half and he eats them right up. Highly recommend!

    One bag lasts me over half a year!

    By on Top 250 Contributor

    I adore these joint supplements for my 7 year old beagle. While she doesn’t have issues getting around, I want to prevent that for as long as possible. Since I work at a vet, I know Glycoflex works very well on dogs so I already trust the brand. These little chew bones are supposed to be fed every other day but I just break them in half and give one half at dinner. They last forever!! Super happy with this purchase.

    Sadly they arrived hard as a rock and I'm unable to use for the small dogs I purchased them for.

    Good for active dogs

    By on

    Recently started giving these to our two 2 year old pups who are very active. I wanted to give them something not too strong to help their hips and joints since they play and walk so much. They love these and think they are treats! Haven’t noticed any huge changes, but feel good knowing that I’m giving them joint support. They run around and are as playful as ever!

    8 years old & acts like a puppy

    By on

    My Bichon has always been an active pup. I’ve recently started giving him these Joint Support Chews within the past year because I thought it would be the best for him to take as he gets older. He loves these chewables!! He is always up and about now.

    Lab with hip problems

    By on

    When I rescued my lab mix, she’d been hit by a car and had a fractured pelvis. I’m using this as a preventive to future hip problems. 4 stars is bc she doesn’t like the flavor. I have to “hide it” in her canned food.

    Easy Supplement

    By on

    Our 10 month old chocolate lab gobbles these down no problem! It’s nice to have the peace of mind that we are doing something good for her hips throughout all of her life stages!
