I make my own treats with a very simple recipe only takes about 5 min to prep and about 20 min to cook.
500 gms of any meat (blended to mush) with a little water
1 cup wholemeal flour
1 cup corn maize
1/2 cup skim powdered milk
1/2 cup wheat germ
extra water if needed
2 eggs
mix all together - depending on the meat you may need more water you want a moist mix like a cake mix.
Grease a tray or line with baking paper and spread mix onto it evenly and cook in the oven for around 20 mins at 150 c (fan forced) slice is ready when it come off the paper without moisture at base. Let cool and cut into bite size pieces, can be frozen. Keep in fridge for up to 7 days
I also add carrots, cooked rice, pasta, sesame seeds
you can get the flours from health food shops
My fussy Huskies love them
