Leo - Named in honor of genius Leonardo da Vinci, Leo marks a renaissance in dog toy design! The original connectable treat-release toy! The durable, hollow-core construction, open neck and two cross-cut holes allow Leo toys to be stuffed with treats. Great fun on its' own or connect two, three, or more Leos to create customizable treat-release puzzles (treats can travel from toy to toy). Feed dinner from a Leo to slow down gulpers, and exercise your dogs mind by giving them a "hunting and foraging" challenge at mealtime. Leo is a great way to help obese dogs lose weight too - extending the duration of a meal can help them feel more satisfied with less food. For dogs 10-200lbs., 8"h x 4"w. Dishwasher safe and also great for fetch, tug-of-war, and water sports (they float too)! Made in the USA.
