Squeaker Does NOT Break in a Day
Size: Large
My mid-size, 40lb heeler mix loves these chew balls. They are easily his favorite toys to fetch, chase and chew on. We’ve had the chew balls for several months, and, unfortunately the squeaker does not break in a day. They are still going strong. Extremely durable and great value for the money.

Very durable, even after the squeaker quits
Size: Large
These balls are really durable! The squeaker inside only lasted about a week, but my dog loves to chase it and just chew on it in his mouth. I took two of them to the dog park, and the other dogs were the same way with them.
