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

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
