Don't let the cute look fool you... He is quite aggressive when you throw him down! Designer for erratic, unpredictable bouncing, this treat dispensing toy is sure to have your dog on their toes. While your pet tries to get the treats out from inside the Monster Mouth, their teeth and gums are massaged by the different sized teeth on the toy. Jolly Pets rubber products are made from 100% non-toxic rubber. This means your dog can chew, lick and bite our rubber and they will not be ill. Our rubber products are vanilla scented. Available in 3" and 4" sizes. Green only.
