VetriScience GlycoFlex Stage III Senior Joint Support Dog Tablets is rated 4.7 out of 5 by 90.
Rated 5 out of 5 by from Gave our senior dog( age 13) life Jake had been abused when he joined our family as a 1 year old. He was a great guy but being mostly golden retriever began to have trouble getting up and down 5 steps when he was 12. We had to help him or he could not make it and at 95 lbs needed two of us. After many pills and various joint supplements we gave the Senior chews a try and within a week noticed a difference. After 3 weeks he was making it on his own. His legs stopped giving out on him. Once in a while he even began to trot a bit. Thanks to these chews we had him happy and mobile for another 18 months. We also give them to our golden retriever who is 9. The vet tells us he would estimate her age to be 6. Orla runs and had no difficulty with stairs. We plan to keep it that way with Glycochews. Our sons 13yo lab takes them too now!

Rated 4 out of 5 by from Good results so far The pills are kind of big so I have to break it up into a powder and mix with her food.

Rated 5 out of 5 by from I have seen a change in condition I began using this product on my 11 year old greater swiss mountain dog who was showing her age in her hips. Two weeks after a daily dose my dog began to climb the stairs nightly to sleep in our room again after 18 months of staying on the first floor. She also began to show more interest in walking the block again. This product was the only change in our routine so I am positive it is making a difference in my dogs condition and comfort.

Rated 5 out of 5 by from Great deal My seven year old Golden is a big fan of the chews, and has been on them for a couple of years. I wasn't sure he'd go for these tabs, but I had to try as each has all the same active ingredients as two chews . . . so the price is really attractive. While he doesn't drool and wag his tail furiously at the prospect of the tabs (like he did with the chews) he does in fact eat them, which is all I need.

Rated 1 out of 5 by from Dog won't eat them "Glued-together" pills with no freshness seal on bottle. Not surprising my dog won't eat them no matter how yummy I try to dress them up. I trust her judgement! Given the pressed form I have to wonder how effective these really are anyway. It takes high heat to make a hard pill like that.

Rated 5 out of 5 by from Very happy with results Since starting GlycoFlex 3 a little over a week ago, my grumpy old man (11-year old shepherd mix) has been a lot less grumpy and often acts puppyish! My goofy old man (11-year old lab mix) is even goofier!

Rated 5 out of 5 by from My dog enjoys these tablets I had previously ordered a similar product that was in treat form, which my dog would not eat. She loves these tablets and thinks of them as treats. Too soon for us to see joint benefits, but 5 stars for my dog enjoying the taste!
