Weight control on a raw diet

Brutus had a weigh in today at the vets just before he had his vaccinations and tipped the scales at 18.05kgs. He doesn't look fat, but a couple of people commented on him looking a bit chunky round the waist. After I controlled myself and didn't reply with "so do you", I started to think maybe he could loose a little weight. I have based his raw diet on an adult weight of 18kgs, same as his dad. So he gets about 500g of food and a few training treats each day. In terms of exercise, it's getting really hot now, average of 39-41 Celsius per day so we walk early morning and late afternoon for 30 min sessions.

With regards to him loosing a few kegs, are there any raw meats that are high in fats and should be fed less? Also, in terms of him dropping a little weight, is it just a matter of decreasing his food intake?

Cheers

Look at it this way, alot of people oversees on raw as the portion can look tiny!

My chance just short of 50kg only eats 1% of his body weight a day to maintain his weight that I'm happy with whereas Harvey eats about 3% so essentially they get about the same amount of food

I'd cut his food down and up exercise if you want him to lose any
