I keep getting these because my puppy likes them and they are safe for her to chew. They don't break off into pieces that can hurt her. I have a "Premier Busy Buddy Bristle Bone" that unscrews on both ends. You just slip these on and give it to them and it will keep them busy for a long time. I have the small size, but they have larger ones for bigger dogs. They also have one that has a sort of ball in the middle that these little round chews slip onto also. It's a pretty good product and I'll keep getting them until she gets tired of them.

My dogs favorite treat.

Size: 0.06 Ounce (Pack of 16)

My dog loves these. He has tummy troubles and these do not seem to upset him. He’s never had diarrhea from eating these. The size is perfect. He’s a small dog and has no problem chewing these up.

Gave my dog diarhhea

Size: 0.06 Ounce (Pack of 16)

I love the design of these toys - keep my pooches busy for a good amount of time. However, these treats gave one of my babies diarrhea, possibly due to the sorbitol, a known laxative for dogs :( My dogs are both ~11lbs, and they would only get one disk at a time in their toys, and still one had loose stools. I know it's not the rawhide because he dosen't have trouble with regular rawhide, but these are so soft I can only assume they have too much of other ingredients inside. Update: I just tried the dental disks and my boy that was sensitive to the regular refills has no issue with those. There's definitely an ingredient in these which he is sensitive to.
