it's a little smaller than I expected but it's perfect for my lil guy. as soon as he's feeling better I'm sure he will be chasing it all over the house. came in earlier than the delivery date.
I thought that the ball would move more freely but in reality the material is not like a rubber ball, it is a fairly rigid plastic and it has vibration, it makes a lot of noise on the ground. My dog was not very amused, rather it was scared.
