I had a stability ball until the dog (then a pup) thought it looked like a fun toy. With so many more routines using this I thought it was time to replace it but worried about how long it will last. Muggs (pug/fox terrier mix but other than the pug appettite he is all terrier) is now 4 but still very playful and puppyish. Has anyone else had this problem? Not sure if spraying the ball with bitter apple will help. Thanks
