If your dog or puppy needs a challenge, a distraction, and a treat all at the same time, the Busy Buddy Barnacle will keep him happy. The Barnacle’s patented “Treat Meter” randomly dispenses treats to help relieve boredom and prevent anxiety. The flexible prongs can be trimmed to increase the flow of treats. Fill with treats, kibble or mix it up for a fun challenge. Made to withstand chewing.
