Of course the dog never gets left out at Christmas, does it?
Unfortunately mine has got such a sensitive tummy he can’t have any of the usual treat things from the shops. He only has to look at dairy/soya/gluten/egg and he’s running for the door again! So on a very special day he gets homemade treats.
I use cheap crunchy peanut butter, mix with rice flour until it will roll into little balls, but not that much to make them too dry they still need to be sticky. Then simply roll in porridge oats and chill in the fridge until needed.
He knows I’m making them though so he needs them NOW!
I suppose the size you make depends on the size of your dog.
