Good toy for dogs
Size: Large Size 3, Color: White-Blue
Bought this for our husky. Thought it would be bigger but it’s a good size for her. She has not managed to tear it apart after having it for a few months.

Puppy proof!
Size: Large Size 3, Color: White-Blue
Purchased the blue ball. Puppy loves to carry and shake the ball with the strapes in her mouth. Lots of bite marks but hasnt popped it. We bought 2. She plays in her fenced in yard with them. Fun to throw and kick around.
