My dog has had 2 in the last 2 days and his stool got really loose from them. I have to take them back even though he seems to like them. He seems sensitive to several different chews we have tried. We have had him for 3 months now and think he's part boxer/husky and about 45 pounds and a finicky stomach. I think these are a really good deal but pretty sure these sticks are causing the problem with soft stool, unfortunately.

All 3 of my dogs got diarrhea in the same day when I gave them to eat the sticks and they only ate half of one stick. They all had diarrhea for 2 days and at first i thought it was their food, but it wasn't. Can you imagine 3 dogs having the runs for 2 days and waking up every hour in the middle of the night to let them out, than having to clean the yard after that. If you can't than go ahead and risk it, buy it.

Bought for Friends dog. He seems to be moving better and gets excited when he hears the bag

The dogs love these! They seem to really help with their joint aches.

My Weim loves these and looks forward daily to enjoying. Great for her teeth and keeps her busy.

My Tank loves theses. Just wished he couldn’t eat them so fast. lol

Seems good for our 7 month old puppy.

Our dog loves these Collagen sticks

My picky dogs love these!

My dogs love these! I but then every time I'm in store. I have never had an issue with them.
