this is what I make up for mine...
I buy freeflow raw minced beef from P@H, a third of a bag feeds my 5 for 1 meal.
I let the meat defrost, and at the same time defrost half a bag of frozen mixed veg by pouring boiling water and leaving to cool, in a large tupperware container.
I then hand blend the veg until it is like a pulp, and add the defrosted meat.
The mixture is very wet, and I add about 500g of oats to bulk it out, and it becomes like a stodge (mix well so no dry oats)
It is then divided between the dogs, and every other meal I add about a tablespoon of oil.
so bear in mind the amounts above are for 4 Deerhounds and a Lurcher for 1 meal, but it gives some idea of how to make a "dog food"
I also buy 500g packets of minced chicken from the local kennels, and will substitute 2 bags of chicken for the mince and make up the meal as above.
It's all a bit of trial and error, find what works for yours
