Favorite toy.
Seems to be of good quality. There are probably a dozen different name brands for these balls. Our puppy loves these. Our son’s 90 pound golden lab has had one for a couple years. He has his outside and it’s a very similar design. Although not the same manufacturer.

My dogs favorite toy!
They can’t wait for me to put air in the ball. Second picture is my active dog asleep from having so much fun with her new soccer ball.
