Ivushiq,
i think you are soooooooooo so so smart to even think about this!! GOOD FOR YOU! It's much easier to prevent a dog from getting fat,
than to cure a dog from being fat!! I once inherited a fat dog, and wow, it's harrrrd to get weight off of a dog!
My dog is 50 lbs. He
can get chubby, and i have to worry about that every winter..as soon as i spot an extra pound on my dog, i cut his food portions back, unless it is wintertime, when i do let him carry a few pounds extra for warmth. But every spring, he goes on fitness program to get those 2 or 3 extra pounds back off of him for summer time.
On days when i do use food for his tricks,
i often give about 1/2 cup of treats.
If i use over half a cup of treats i will reduce the size of his dinner.
I'd rather my dog be on the slimmer size, than be too big.
Occasionally, i skip his dinner entirely, as i hear it's not natural for a dog to eat twice a day, eveyr day, and i hear skipping meals helps a dog's metabolism, and it does seem true.
Or, i will use his entire dinner as training treats, and nothing goes into his bowl.
I have no problem skipping my dog's meals now and then,
and instead, to prevent Buddy from wondering what is wrong, i just play with him really a lot or take him for extra walks. He then seems oblivious to the fact he got no evening meal.
I usually use this recipe, and i usually use raisen-sized bits of treats. This recipe is easy to make, it's cheap,
it's healthy, and dogs love it.

or I use bits of meat cut up small, or hotdogs. sometimes i save up my almost-empty yogurt cups and he gets to lick the yogurt cup clean for his reward.
I almost nevvvvvvvver use store bought treats, as i think most store bought treats are horrible for dog's health.
sometimes, i use tug-toy play for his prize, which he enjoys --- nice change up, especially for tricks my dog thinks are kind of dull , the tuggie-toy play as his reward adds to the FUN for my dog.
Some ppl here use tennis balls or frisbees for their trick rewards.....a reward does NOT have to be food all the time. You can click and throw a tennis ball, if that is a good reward to YOUR dog.
