Use just enough peanut butter to coat the kibble, which usually amounts to 1 tbsp. per 1/4 cup.
Stir the peanut butter into the kibble until the kibble becomes evenly coated.
This is the fun part! Okay, maybe it's only fun for some of us.
But whether you use your fingers (like me) or a spoon for this, be sure to get the peanut butter mixture all the way to the bottom of the Kong. This hard-to-get stuff at the bottom challenges your dog, keeping them occupied for quite a while.
At this point, your dog is likely to be watching you very closely and drooling nonstop. You might want to make sure their water bowl is full!
Spread a little more peanut butter on the end of the Kong Toy to create a tantalizing cap that locks in the mixture.
It typically takes around 6 hours for these to completely freeze, so I recommend freezing them overnight to use them the next day.
