Other Tasty Kong Recipes To Try
The following Kong stuffings are made with one or more human food ingredients:
CHEESY ELVIS: Combine a ripe banana, 3 spoonfuls of peanut butter, and a slice of cheese. Mix until blended well. Fill the Kong and freeze.
MONSTER MASH: Instant mashed potatoes (without the salt) -- or leftover mashed potatoes from dinner -- mixed with crushed dog biscuits.
DOGGIE OMLET: Combine a scrambled egg, some beef, yogurt, cheese and mashed potatoes all together
FIBER CRUNCH: Combine bran cereal with some peanut butter.
KONGSICLE JERKY POPS: The equivalent of a popsicle... Seal the small hole of the Kong toy with peanut butter. Fill to the rim with water and a pinch of bouillon (or just use chicken broth instead). Place a stick or two of beef jerky inside. Freeze. (This one gets messy in a hurry, so it's recommended only for outdoor use.)
GOOEY CHEERIOS: Combine cheerios and peanut butter. Freeze.
FRUIT KITTY NOODLES: Mix together some dried fruit, cooked pasta, banana and dry cat food.
BANANA YOGURT: Plain yogurt and mashed bananas. (You can also add a little peanut butter or other fruits.) Then freeze it.
PEANUT BUTTER GLUE: Fill Kong 1/3rd full of dog food. Pour in melted peanut butter (after it has cooled from microwaving). Add more dog food, followed by more melted peanut butter until the Kong toy is full. Freeze until solid.
ROCK-HARD KIBBLE: Combine some of your dog's regular food with cream cheese, which acts as a cement, keeping everything inside.
STICKY BREAD: Smear peanut butter on a piece of bread. Fold it over and stuff inside the Kong. Mix together plain yogurt with some fruits or vegetables (carrots, celery) and pour inside. Freeze. The yogurt sticks to the bread holding everything together.
APPLE PIE: Squeeze a small piece of apple into the tiny hole. Fill the Kong with a small amount of plain yogurt. Add a few slices of mashed banana, more apple, yogurt, banana. End with a slice of banana and chunk of peanut butter on the top.
