Forget tennis balls that get soggy and are quickly popped these balls are a solid, rubber, and will never pop — and they float! You can throw The Ball like any other rubber dog ball and have fun watching your dog play for hours. Safe for use in pools. Please choose the right sized ball for your pet – 2.5 in ball for up to 40 lbs. and 3.5 in ball for 40 lbs. and up. Ships in a variety of random and fun colors! Every dog plays differently and, since not all toys are created equal, it’s always best to keep a close watch on your pup in case things get ruff. Take care to choose the correct size ball for your dog. Supervised play will help toys last longer and most importantly keep your pal safe. No dog toy is truly indestructible, so always remove the toy from playtime if pieces begin to break off.
