Here is the recipe for Jack & Scout's frozen treats. it is very easy. I use a blender.
I purchased small plastic containers that are freezer safe for the treats. The containers are reusable, so they are perfect.
Ingredients
1 large container of Vanilla Yogurt - fat free is fine (2 lb)
2 Tablespoons of peanut butter
If your dogs like fruit such as bananas, throw that in. Scout likes it, but Jack will not eat bananas. I have tried apple sauce, but peanut butter is the favorite here.
Instructions
Place half of the yogurt in blender, add peanut butter and then add remaining yogurt. Blend well. Pour into containers and freeze.
That's it. This makes between 12-14 treats depending on how full I fill the cups. I buy a generic yogurt which is $1.67 currently at Walmart. So, this is a very economical treat for my dogs and they love it.
