I gave it 2 stars as it lasted 2 days. I have a weim that LOVES to chew on balls. She was able to get into the seam of the ball the first day with her teeth, then destroy the seam the second and the ball was in two pieces. Thought it might have been a faulty seam, but she destroyed the second ball in 3 days. She only gets supervised ball chewing time for approx 1-2 hours a day. I would not buy again.
