This month we're going to start the 3-part mini-course "how much to feed your dog". As you probably know a lot of dogs, and people, are overweight and so it's better to take preventive measures and to not overfeed your dog.
We're going to play with numbers a lot these three lessons but the outcome is well worth it. And we'll take it step by step, so don't be afraid.
The SI base unit for mass is the kilogram.
1 lbs = 0.45359237 kg.
1 kg = 2.20462262185 lbs.
Determine your dog's current weight at the vet's (as they usually have large scales) and write it down.
When you have his weight in lbs, then first convert this to kilograms: multiply your number by 0.45359237 or use this online converter.
Your dog's ideal weight will be breed and gender dependent, so I cannot give you a number for this. Ask your dog's breeder or the vet. For reference purposes I'll list a few dog breeds and their average body weight in kg.
Purina has created a handy list to score your dog's body shape. You can use this to determine whether he's overweight.
The body weight in kg^0.75 is his metabolic weight (you'll be needing a calculator for this). I'm taking my dog as an example: his body weight is 30 kg (66 lbs), so his metabolic weight is 30^0.75 = 12.8 kg (28 lbs).
Take your dog's metabolic weight, which you calculated in the previous step, and multiply this with 275 to get to his BMR (Basic Metabolic Rate).
Multiply the BMR with 2 to get to his maintenance energy requirements.
In Kensho's case: my dog's body weight is 30 kg (66 lbs), then his metabolic weight is 12.8 kg (28 lbs). His maintenance energy requirement is 12.8 × 275 × 2 = 7051 kJ per day (1692 kCal).
The maintenance level generally equals twice the Basic Metabolic Rate. Of course this is lower for inactive dogs or dogs that need to loose weight and higher for active dogs.
The outcome of your calculation is just a rough measure. Dogs differ in metabolic state and energy conservation characteristics. One breed is more efficient at producting energy and converting it to muscle power than others. So… take the result as a guideline only.
“When your dog is fat, you're not getting enough exercise.”

Next we'll calculate the energetic value of dog food to get another piece of the puzzle.
“A dog is one of the remaining reasons why some people can be persuaded to go for a walk.”

All the best and paws up,
