frozen dog treats/keeping the dogs busy while away

Just a quick post about the treats I give my dogs when I go to work each morning.
My sister seemed surprised by my simple recipe so I figured I'd share it here.

2 coffee cups of dry dog food (probably about four cups?) (I buy costco's dry dog food, but any dry dog food would work).
1 can of any wet dog food.  I've used all types.  It's all the same.
2 cans full of water from the wet dog food can to rinse out the leftovers.
Mix it all together and let it sit for about six hours or so.  That way the dry dog food absorbs the water, and is mushy.
Pack it all in Kong type doy toys with a spoon.

I can fill ten medium size kong like toys with the above.  Perfect for a work week.

Keeps my dogs amused for about an hour each day.  
 

I combine mashed bananas and almond butter, with the same effect.
