How long does this take to “kick in”? I have a 20-lb cat and no improvement in almost a month... should I keep giving them to her because it takes a while? The vet told me to get these....
Answer by ChewyOct 17, 2020
The amount of time it takes for these chews to have an effect on your pet will vary based on their current condition, weight, and eating habits among other factors. We recommend reaching out to your veterinarian with any questions you have regarding the efficacy of this supplement.

is this unconjuguled collagen
Answer by ChewySep 12, 2017
Flexadin Advanced contains undenatured collagen Type II.

Can dogs with renal insufficiency take these? What is phosphorus content?
Answer by ChewyMay 20, 2021
There are no contraindications for Flexadin Advanced Chews with UCII for Dogs & Cats. The manufacture does not measure for phosphorus content. These chews are only 3 grams each and the directions are to give 1 chew per day for any size cat or dog. It would be a very small amount of phosphorus in each chew.

Did not work for my dog

I have a 90 lb pit mix that is about 13. My vet recommended these for joints/mobility. After a few days of being on them she started drinking excessive amounts of water and having explosive diarrhea. She used the bathroom in the house for the first time in 8 years. I still continued to give them to her for a few days not realizing these were the cause. After stopping water consumption and bowel movements became normal again.

Superior Product

This treat is the first treat supplement for hip and joint treatment that I’ve gotten my cat to not pick out of her food! I’ve had her on them for about two weeks and she’s running around more, playing with more of her toys, and even let me pet her hip that showed the most sensitivity. Very impressed with this treatment and highly recommend for picky cats with hips and joint sensitivity!

Not for sensitive stomachs

My dog has severe allergies and a sensitive stomach and now we know chicken is a no go. I was hoping these would help her arthritis but after giving her two she ended up with a really upset stomach so we stopped giving them. I've heard really good things about these, just not going to work for us.

I’m a puppy again

Jaxon is 80lbs and he is a puppy again! After just a week of this he is skipping around and wanting to play in the yard again. He’s 10 and had slowed down tremendously. Our vet recommended this. I will never not have a daily night time treat again! He’s so frisky! Now I’m the one tired.

It Works for So Many/Vet Recommended

Unfortunately, I have an elderly picky cat who stubbornly refuses to eat anything but a few expense select foods. I gave it 4 stars, because I didn't want to low rate it just because my cat refuses to take as treats. Tried mushing up with food, cutting in small pieces, dissolving in tuna juice - NOPE, won't take! So, I cannot speak to the efficacy of the product, but just wanted to share that some cats just won't take these no matter how much other cats enjoy them! I was able to administer some liquid meds but after a week or so, she spent the entire days hiding under the bed. I give up. The poor little thing seems better off with slight arthritic pain than spending all day hiding and not enjoying her sunshine window sills.

Good Stuff!

This has really helped our dog with her arthritis. She’s been much more lively and happy since she’s been taking these. So glad we got them for her.

My cat loves these

Got these for my elderly cat who can be pretty picky and he loves them! He seems to be a little bit less stiff after starting taking these, but that also coincided with a general turn around for the better in his health so can't give all the credit to these supplements but I'm going to keep giving them to him just in case
