DON'T buy them, the furry part of the ball comes off and my dog, a GSD, took the ball apart, broke it into two pieces after maybe a day or two. PLUS HE SWALLOWED THE FURRY PART OF THE BALL AND CHOCKED! Apparently he likes to pull the skin off of the ball once he got the ball open. Luckily he threw it back out. I bought probably around 20 of these balls (accidental order) and after 3 months I have none left. Stick with the gummy balls, they are great, no chocking hazard and they can be thrown pretty far.
