I had a dog who ate so fast he almost choked to death three times. Not all dogs know when to stop eating! Yes, they can inhale their food.
I would only give the amount that is the proper daily required for her breed and age ... give or take a smidge depending on her weight ... whether she is over weight or at a good weight. You could space them out into three meals and it would be good IMO. A dog can over eat and have food bloat ... which is serious. I just had something similar happen to one of my little dogs two weeks ago. He ate a bunch of " stuff " and landed in the hospital. Part of that was a massive pile of vomited food. Don't know what happened other than he must have ate his brothers dinner too! ( and maybe some pillow stuffings )
Sometimes smaller dogs seem to need smaller spaced out meals to prevent hypoglycemia. ( low blood sugar )
For dogs in heat ... I have no answer. Mine is spayed. I usually have male dogs.
Also, worms and other medical conditions can cause ravenous behavior. If the vet says all is normal ... I would space out the pups meals.
