Guzzy makes it easy to place food inside, but difficult to remove for your dog. It helps prevent dogs from eating too fast and gives them time to digest their food to effectively prevent visceral diseases. Guzzy also prevents your dogs from barking, digging, biting and can aid in house training. It can also be used to relieve stress such as boredom and separation anxiety. Easy to wash, durable and long-lasting and made from 100% natural rubber. Great for puppies and super small dogs like Chihuahuas and Yorkshire Terriers. Available in Small sizes
