This year brought a new arrival- a labrador puppy. She loves her food but treats are costly and also she is a typical lab and so we need to watch her waist line.
I've made her some sweet potato chews which are very easy and cheap (not don't allow too many at once since they can upset their tummy).
Take a few large sweet potatoes and wash and slice fairly thickly. Bake on the lowest setting for about three hours (turning half way through). They will come out soft but they will toughen on cooling.
These biscuits are also very easy to make and cheap.
Begin by combining 2 cups of wholewheat flour and 1 cup of oats. Add to this half cup of vegetable oil, 1.5 cups of water 1 tsp vanilla, 1 tbsp honey, 1 beaten egg, 3 tbsp crunchy peanut butter and 1 mashed banana.
Combine until you have a fairly even dough- add more water or flour as required.
When you have a workable dough, line and grease a baking sheet. It is quite a sticky dough so to save your sanity, rather than rolling it out and cutting out shapes which can get messy, oil your cutter and then press the mix directly into the mould on the sheet. You should be able to then just push out shaped quantities of the dough.
I made these quite large since they cook better I feel and I can then break them up as required (or give her a whole one for special treats!)
Bake at the lowest setting for 6-8 hours until they are really dry and hard. You can store them in an air tight container for a week or so.
