Ali,
If we are talking baked bean tin size can then I think that half a can with bonios (making up the mixer part) during the day is probably enough food for a sedentary, probably spayed cocker.
Also one persons idea of skinny is a dog that is just right!
One of my Elkhound bitches wehn younger and spayed could only have 4 to 5 ounces of a maintenance type dry food. Last year I had to increase the quality and amount, as due to the aging process (and suspected early cancer) she was loosing muscle mass/not absorbing it as well as before.
She now gets 200grammes (7 ounces) of a good quality highish protein complete same as the young ones!
They are aprox 20kg (43 pound) bitches. They get plenty of excersise.
If I fed tins they would only get 1 tin, or 3/4 and some biscuit.
I have resorted to this when on holiday.
