In short, yes, it is the same concept. The biggest problem with canine companions is overfeeding for the amount of exercise they get. When they are active, and by no means 5 hours worth, I feed the dogs more. When they are inactive as they are right now while I am remodeling, I feed less. Trust me, canines do not and have not ever voluntarily exercised 5 hours a day. Mine come back t-i-r-e-d after a three hour exploration and promptly conk out for a while.
Go by feel on whether your dog is eating too little or too much. My sister's beagles get 1/3 cup of premium dog food twice a day and they are farm dogs. Run your hands down the side. Can you feel ribs without seeing them?
A tired dog is a happy dog but an exhausted dog is asking for problems.
