  • Works great for arthritis

    By on

    My lab/shepherd mix is ten and when I adopted her at age one, my vet diagnosed her with some hip dysplasia. I did not want to give her an anti-inflammatory, which I have always had to do as my other dogs have aged, so my vet recommended Glycoflex -- one after each meal. I have done this every day of her life and have only occasionally had to give her an anti-inflammatory for a few days. It works so well for her that I started taking glucosamine myself! Also, she loves the flavor and there is never any chance of my forgetting to give it to her because she sits and stares at me after her meal if I have forgotten.

  • Obviously, not the best tasting

    By on

    We bought these for our 2 little furries. The male takes his right after breakfast every morning and chews it right up. The female takes hers and brings it into whatever room the male is in and leaves it to taunt him. She'll usually eat hers after about five minutes so they don't really seem to see them as a treat. As long as they help their joints, that's the important thing. It's too soon to tell yet.

  • Saved our pup

    By on

    I am so thankful we found this! I read tons of reviews on similar products and decided to give this one a try. We had a vet tell us our Boston would need surgery for his luxating patella. We decided to try this first based on some other reviews, so thankful we did! His knee has been staying in place and he has only been taking them a month! Our Boston loves the taste. My husband thinks they smell bad but I think they smell like canned tomato sauce.

  • Such an improvement

    By on

    Ever since starting these my 12 y/o Brittany's mobility has improved so much. She's having less trouble getting up, doesn't fall anymore, and is even able to walk faster and longer distances on our daily walks! Such a lifesaver - literally.

  • Soft chews vs. tablets

    By on

    Both my dogs like the taste better. I used to dip the tablets in peanut butter to get them to eat them, but they think the chews are treats. My vet recommended these for my senior dog & my 3 year old with luxating patela. Very pleased!

  • Can't evaluate...rejected by dog

    By on

    Sorry to say I can't tell anything about this product except that my dog won't even try it. I've tried every day since receiving it to give it to my Shih Tsu. She won't have anything to do with it. It is a little large to try to break up and sneak it into food. Hoping to find something like this that my dog will consider a treat. Might work better with another breed, especially a larger one or one less picky than a Shih Tsu.

  • Great product delivered on time

    By on

    I've been giving this product to my dog for about three years. I didn't know the affect it actually had until one day I ran out. Within a few days my five year of German shepherd didn't want to jump and play. He was happy but I could tell something was just a bit off. I ordered the product from chewy and within two of three days my dog was back again to being happy and jumping/ running acting young again.

  • This product is really working!

    By on

    I have only been using this product for a week and my 12 year old Australian Shepard really seems to be moving more freely and has a lot more pep! I give it to her twice a day in her in her food.

  • My dog won't eat it. Waste of money.

    By on

    My dog won't eat it. Not at all. Not interested. Nada. Waste of money. She did love the Dasuquin with MSM so, I guess I will have to revert back to these even if more expensive and almost never in sale.
