Two 32-oz. tubs plain or vanilla yogurt
One 6-oz. can tuna in water
2 tsp. garlic powder
24 3-oz. plastic (not paper) bathroom cups

Open yogurts. If they are full to the top, use a spoon to scoop out one bathroom cup. These will be frozen as plain yogurt. Put half of the can of tuna in each yogurt container. Add 1 tsp. garlic powder to each container. Mix each container thoroughly. Use a spoon to scoop the mixture into the cups. Place on tray and pop in freezer overnight. Makes approximately 24 treats.

Variations:

Natural Flea Prevention: mix in garlic powder, brewers yeast, and fennel seed
Veggie Delight: mix in cooked peas or other veggies
Chicken Icy Paws: used canned chicken instead of tuna
Potassium Boost: add in a mashed banana
Can also use standard ice cube tray instead of plastic cups. When frozen, pop out and put in plastic bags or wrap in wax paper.
