Buster needs to be kept lean due to elbow displasia. He also is a plodder, the only thing that ever speeds him up is when we occasioanlly bump into his rottie friend.
His weight controll is done via diet rather than excersise. I've never found tripe to be something that puts weight on him, but he's only ever fed is as past of his diet, not in addition to a normal ration. Anything fed in addition to will add weight on.
Buster is approx 90kg, he has 920g food per day
(this is maintenance amount,not a diet amount), split over 2 meals
(420g of complete + 400g of wet).
If he has any of our left-overs, his evening meal is reduced accordingly.
If he's ever looking/feeling a little heavier, his complete will be reduced by a fraction for as many days as is needed to get him back to normal. I don't bulk out his food if he's on reduced portions.
ETA be strict on weighing portions out. A little over portion size at every meal soon adds up to extra meals.
