My dogs love these and they are so easy to make.
No Bake Dog Treat (balls)
3/4 cup Peanut butter (all natural is best)
1/4 tsp. cinnamon
1/4 cup water
1-1/4 cup oats
Line cookie sheet with parchment paper. In bowl mix together peanut butter, cinnamon and water until combined. Slowly add the oats 1/4 cup at a time until completely mixed in. Scoop by the spoonful onto sheet. Chill in fridge for 1 to 3 hours before feeding dog. To freeze place in ziplock bag and freeze. Get out as you need.
Note** When I made these the first time 1/4 cup of water was not enough for the whole all the oats. So I just added little more water until I had a dough. Not a sticky dough.
