Don’t waste your money. Your dog will be eating plastic…
Color: Pink
My dog ends up chewing the plastic ends which is destructible, so I took it away from her. She loved it though and the colors are cute. But eating plastic isn’t ever a good thing. I recommend sticking to actual bones or something else, not this.

Cute toy for small dogs!
Color: Pinata Dog Toy
My dog is obsessed with this toy. This does not have a squeaker in it which is great cuz she doesnt like them. The crinkles and rope seem very durable. She did eat the tail very quickly but overall its held up well! Great tug toy for a small dog or puppy!
