Our puppy is teething, and these are so helpful during this time for her! The only issue are the fabric strips come off, and we have to throw them away so she dont try to eat them!!

These toys are as durable as jello!
Color: Pink1, Color: Pink1
This is probably the worst product I've bought for my dog. These toys have the durability of a cup of jello, my small dog seen in the photo destroyed it in one night. Small dog, big dog or puppy, buy them high strength durable toys, my dog was smart enough to not swallow any small pieces she bit off but I cant say other dogs won't swallow the small pieces. I don't recommend this product for any dogs what so ever!

Fave dog toy!
Color: Betty Bigfoot
Great toy! My dog prefers the ball inside which is great for chewing on, bouncing, and playing fetch. Very thick rubber, lasts a good while. The outside cover is pretty tough, but for those who like a challenge it should last a little while. It really depends on how determined and fierce the dog is about chewing! We’ve had 3 of them. We always keep a back up for when one expires!!
