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.
