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)

Keeps the puppy entertained for hours
Size: X-Large(8")
My dog loves this. I've had to buy two because my dog destroyed the first one but there's only so much you can do with a 5 month old german shepard.

Not durable and lasted a week
Size: X-Large(8")
Had it a week and it popped. The durability is not good! It’s not chew resistant, the value for the money is poor! My dogs enjoyed it for the week it lasted it was a good size , however extremely disappointed!
