Jacob has recently been looking chunky so his food has been reduced from 120g a day to 100g a day. It will depend on what food you give as to the amount the dog should be fed. Jacob is on Barking Heads Fusspot and he only needs to look at the food to put weight on

he now has 40g for breakfast about 7am, a bonio at lunchtime, 60g for dinner with a large portion of veg (green beans, broccoli, cauliflower, and just a couple of carrots due to the sugar levels in them) and then a small biscuit at 7pm. Out of all of my dogs, Jacob is given the smallest amount of food, but weighs the most. If I don't give him any veg then he is a nightmare with poo-eating but as long as I fill him up, he is generally okay.
