Answer by ChewyFeb 09, 2019
These supplements contain 24 Calories per chew.

My yorkie only weighs 4 lbs and has bad joints. He limps all of the time. Are these safe to use for such a small dog? If so, should I break them up and only give him part of one? Thanks.
Answer by ChewyFeb 04, 2019
This supplement is suitable for all dog breeds. It's recommended to give dogs under 30 pounds one chew a day.

If your dog is less than 30 pounds it says feed every other day. Can you just split it in half and give half a day?!! It seems an odd option and so likely to forget when you have or haven’t given it every other day
Answer by ChewyMay 18, 2022
Half of a chew can be given per day to a dog weighing less than 30 pounds.

Where is the sell by date on the package for these chews?
Answer by ChewyOct 01, 2022
The expiration date is located next to the lot number on the back of the package or bottle. The lot # is 8-9 digits long, then a space, then 4 more digits indicating month and year. For example, a product with the number 999999999 0121, would expire in January 2021. We do not recommend usage after the expiration date.

Help for joints

My older dog has a bad knee. Our vet recommended something like this. Seems to be helping, but they smell awful. Our cat sure would like to try one because of the odor!

Just O.K. Hard to tell

Dog does not like the taste so I have to cut into very small pieces and mix with food. Not sure if it benefits his joints. Another relative of mine swears that it helped her older dog. Time will tell

Helping my dogs

I have one dog that injured herself and was paralyzed for 3 months. She is around 12 years old. I have another dog that is 11 years old that was having a lot of trouble walking and was even limping. My vet recommended this to help and a few other brands. I tried other brands, but couldn't get my dogs to eat them. My dogs look forward to these and eat them with no issues. My dog is no longer limping and even getting up stairs a little better. I will continue to use this for them.

Amazing price!

I usually buy these from my vets office but moved further away from it and didn't want to go all the way there. So on a wim I checked on Google and found these on sale at the time for half the cost they are for the same count at the vet!!! Will be ordering again!!

Liver chews for joints

The package arrived in great order. My dog ate the first one no problem. Since then, she doesn't seem to like either how it chews or the flavor. I have broken it into 2 pieces to try to get her to eat them more easily. It may be my girl is a picky eater, but not sure if other dogs are also not "thrilled" to eat these.

Doggie meds

I would recommend Glycoflex to any dog owner. They are easy to give and my Lab loves them. No problem getting her to take her joint med's at all.
