I got these for my puppy when we first got him. He loved them and they lasted several months... however, at the end he managed to chew through the plastic, splitting them into pieces. He didn't swallow any of the, thank god, but there definitely was the risk for that.

Pros: love it, good for teeth

Cons: after lots of chewing breaks into pieces

I loved these keys! I purchased them for my second dog Baylee and we had them for years! I think that these keys are super enjoyable for the dogs not only because of the nylabone chew factor, but also because the dogs can try to get the keys off of the ring.

Pros: Great!

Cons: None

My dog absolutely loves these keys. She can have fun with them for hours without getting bored.

Pros: lasts a very long time

Cons: none so far

Our dog is mad about these and he's not much on toys. Sometime he even tries to hide them.

Pros: Can't keep them away from the dog

Cons: None

These are reasonable in price and my dog loves to chew on them. A good product.

Pros: My dog loves these

Cons: None
