Must have for a young puppy
Size: Small (Pack of 1), Color: Blue
Very helpful for our young puppy. Cleaning it isn't the easiest, but cleaning advice is easily found online and it's worth the hassle to have a durable lasting toy around

Perfect for small senior dogs!
Size: Extra Small (Pack of 1), Color: Pink
So I actually bought this for my senior Bolonka. She has a neurological disorder that does not allow her to have hard bones or treats, plus I am trying to protect her teeth for as long as I can. This is a GREAT toy. I like to fill up the middle with yogurt or peanut butter and things she can lick instead of bite into. This is the PERFECT size for her. She likes to play with it even without a treat on the inside. She just carries it around the house , as its not heavy at all, and throws it around, it is too cute! It is not loud at all, the only noise that comes out is if shes got a ton of saliva and her teeth rub against it. I just pulled it off the packaging, washed it, and it was ready to go. It will last forever with my baby because she doesn't chew hard so I am unsure about the durability for bigger pups or dogs who are heavy chewers. I am so glad I got this for her and I would HIGHLY recommend it!

Good product misleading size.
Size: Small (Pack of 1), Color: Blue
Really disappointed about the size. It is way too small for my berniedoodle. He still likes it for play but I’m afraid he might swallow it. It’s very sturdy tho and is chew resistant. I guess I didn’t pay attention to the size. Looked big in the picture.
