Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.

Too big for puppies
Color: A.Green+Orange
The balls were a bit too big for my 6 month chihuahuas:/ they are as big as a tennis ball so puppies didn’t like nor play with them
