We don’t sell the commercial products that are available for stuffing Kongs. We would rather know what our dogs are eating!!! Our tip for stuffing a kong is:-
Take some of your dogs normal kibble and soak in water till soft.
Add some grated cheese or peanut butter and mix.
Stuff your Kong with the mixture and then place in the freezer.
Give the Kong to your dog while it is still frozen and watch the fun!!!
