Zeus DUO dog toys are a line of multi-textured fetch balls designed to provide hours of interactive fun and play. Nothing is more fun than playing a game of fetch with your furry companion. Dogs love to chase and retrieve objects. This urge to track down and bring back items is a part of their natural hunting instincts. Playing fetch with your dog not only helps him burn off excess energy and engage his hunting instincts, it also helps provide you and your pet with the ultimate bonding experience. Emitting a rewarding squeak as your dog bites down on them, Zeus DUO ball toys are ideal for a quick bout of active fun, at home or on the go.
