Kong or Bone Filler

When you are left with a bunch of empty marrow soup bones that have been happily devoured by your pooch, fill them with a tasty treat. 

Mix together:

plain mashed potatoes
an egg
some chopped cooked veggies
a little chia seeds
oats

Mix it to a consistency that won't run out the other side of the bone when you're filling it.

Pop them in the freezer. Any leftover filling can be frozen in an ice cube tray.

Just grab one from the freezer when someone deserves a treat. 

Your canine buddy will love you for it!
