My Pom/Sheltie mix is 8 yrs old. Should I be buying the senior glycoflex?
Answer by ParkersmonAug 15, 2021
I would recommend the senior Glycoflex for the 8 yr old. My 7yr, 8yr & 10yr old dogs are all on Glycoflex 3 Senior

What is the difference (other than tablet /chew) between VetriScience GlycoFlex Stage III SENIOR Joint Support Dog Tablets, 120 count and VetriScience GlycoFlex Stage III ULTIMATE Strength Joint Support Bite-Sized Dog Chews, 120 count. Thank you
Answer by ChewyMay 18, 2018
The dosing between the two formulas are slightly different in levels of Vitamin C. The Senior formula contains 30 mg. as for the Ultimate Strength formula contains 24 mg. Additionally, dosing is met in 1 tablet for Seniors, and in 2 chews for Ultimate Strength.

Do these have a meaty taste or smell to them? And can you tell me how big they are?
Answer by ChewyFeb 27, 2018
This product has a strong smell and is about the size of a nickel.

Is there an expiration date for these tablets
Answer by ChewyApr 23, 2018
This product has an expiration date and the shelf life is 24 months.

Excellent results

This product works so well for my aging dog. It helps relieve joint stiffness and helps tremendously with mobility. He’s 11.5 yo and I started him on glycoflex 6 years ago. He gets 1 tablet daily.

Good joint supplement

My dog (70 lb pit mix) had tplo surgery on both back legs in 2017 and 2018 and the surgeon had me start her on a glucosamine supplement before the surgery. She fully recovered from the surgery. She's now 9 and has no mobility issues at all, which I attribute partially to this supplement. Also, it's cheaper than Cosequin and I think the breakdown is comparable if not better.

Good product for joints

My 8.5 yr old large dog and 11 yr old medium sized dog romp in the yard! They get it daily. It helps.

the best joint supplement

I got this for my 6 year old who has moderate hip dysplasia. He was so so so sore and it broke my heart. My vet recommended this. After about 5-6 weeks of use, my dog showed a complete 180 in his mobility. He’s back to sports and running without any issues. He has VERY few bad days now. I couldn’t be happier with this supplement.

Thank you for changing the tablet back to where I can break into with my hands. You had changed the substance to a harder tablet, now back to normal. Been using this product for many years. Thank you!

Kalis mom

My dog has a bone chip in her shoulder that bothers her on and off. Before I started this supplement for her she would have flare ups every month or so for about a week. She hasn't had a flare up in at least six months now and is able to do all the things a dog should do.

Great Product, But Large Tablet

This is a fantastic product if you have a large dog that is not a fussy eater. It has the most comprehensive list of ingredients and impressive amounts of those ingredients! I have a large, 100 lbs, 12 yo lab that will eat just about anything so this has been a great product for us! However- these are very large chewable tablets and they are not really crumbly so they would be very difficult to break in more than halves if you have a picky pup, and there is no way a smaller dog would be able to chew one.

Glycoflex Joint Support

The human thinks it is too soon to tell if it is helping the Greyhound's mobility. He, MorpheusMichael, spit the pill out. Must be the imitation chicken flavor!

Great Joint Supplement!

We have a senior 10 year old boxer and a pre senior Aussie. Both have joint issues but the boxer was down to little activity and had trouble getting up from a sitting position. Within 4 days of starting these we could see a change in her energy level! It's been two weeks now and she is playing outside and uses both back legs to jump up on the couch and come in from outside where she was just using one leg at a time! The Aussie has not been limping or licking her paw for a week. So happy and hopefully they continue to improve after we go to maintenance dosage.
