I've ordered them in 6, 7, and 8 inches I think. She is an aggressive chewer who had destroyed every toy I've given her. But not these! She has chewed off every strap which I've promptly taken from her to avoid her eating them. But the ball itself is chew resistant! I use the small 6" one to play around inside with her and the larger ones to play outside. My puppy absolutely loves playing "soccer" with these. Worth the money IMO.

My dog LOVES this tiny tug ball

Size: Medium(6")

A lot smaller than I was expecting.. BUT my dog doesn’t mind at all. She seriously loves this thing. It goes flat fairly quickly, but that’s what happens with all of her soccer balls, no matter the size. She’s a pitbul catahoula mix and has a strong bite. Considering my dogs chewing abilities, I’m fairly impressed by the durability of the ball, though she chewed through all but one of the rope handles in about 2 seconds. All that said, it’s one of her favorite toys(she’s 13 years old)
