Peel the sweet potatoes and cut into medium sized cubes. Put into a saucepan, cover with boiling water and simmer for around 15 minutes until soft
Take off the heat, drain, tip into a large bowl and mash
Add the grated carrot and wholemeal flour and stir together with a large spoon or rubber spatula
Beat the egg with 3/4 cup water and add to the bowl. Stir together to form a dough, adding a splash more water if the dough is too dry. You want a pastry like consistency that's easy to roll out
Tip onto a work surface and knead to bring to a smoothish dough
Preheat the oven to 160 Fan / 180 C / 350 F / Gas 4 and line 2-3 baking trays with parchment or a silicon mat
Dust some flour over your work surface then roll out the dough to about 1/2 cm thick. If you want a crisper biscuit roll out so it's a little thinner - you'll also get more biscuits!
Cut into whatever shape you (or your pup!) fancy and gently lift onto your baking trays. Re-roll any trimmings and keep cutting out till you've used up all the dough
Bake for 25-30 minutes then cool completely before storing in a sealed container. These keep for around 5 days at room temp or up 1 week in the fridge
These also freeze really well so don't worry you have to give your pup them all at once (even if they WOULD eat them!)
