My 6 month old puppy loved this ball! He's a blue heeler, collie, terrier mutt - 30 pounds. He carried the ball everywhere and loved making it squeak. The squeak wasn't annoying either, thankfully. However, after about a 1.5 weeks the air hole where the squeaker was exposed started to split and tear away. By the end of the 2nd week we had to throw the ball away as the pup had started to eat the rubber in chunks. We replaced it with another 3" red ball, solid, made by another company and it's been going strong for over a month now.
