Got a pup who's a bit nervous every time you leave home? Here's the perfect way for him to chill out. The Chew King Chill Fill is made of non-toxic, natural rubber and fits a meal's worth of treats for almost any pups – it comes in three different sizes – all in a shape that makes a fun challenge for your pet. “Frozen Feeding” - just fill with your pup's favorite kibble, add a bit of water, and park a Chill Fill in your freezer. The next time you're headed out the door, want to slow down dinnertime a bit, or just want to give your pal a treat, take it out and watch him happily go to town.
