Help playtime for your dog last longer with the PetSafe Busy Buddy Ultra-Thick Natural Rawhide Dog Treats. These delicious refill treat rings are 4 times thicker than standard Busy Buddy Treat Ring Refills and are a great choice for dogs who chew through the standard treat rings too fast. The PetSafe Busy Buddy Ultra-Thick Natural Rawhide Dog Treats work with Busy Buddy Ultra Treat Ring holding toys to provide your pet with a boredom-busting play experience. Use the ring treats with the Busy Buddy Ultra Sub, Busy Buddy Ultra Woofer and Busy Buddy Ultra Stratos toys. The combination of toy and treat helps keep dogs entertained for longer periods and helps put the chewing focus on the Busy Buddy toy instead of on furniture, shoes, clothing, or bedding.
