An explosively good time for your dog! These new toys are designed for dogs 30-65 lbs and are manufactured in the USA from FDA compliant, non-toxic and biodegradable materials. The grenade style toy can be filled with treats like kibble, canned dog food, peanut butter, or your favorite dog treat recipe and it can be frozen. The grenade, which measures 4.6” tall and 3” wide, can withstand the abuse of most “power chewer” dogs, and the black Magnum style has a special additive that increases tear strength even more. All USA K9 toys are veterinarian approved, dishwasher safe and easy to clean.
