It is dependent on your cat. You need to know whether your cat is food-anxious or not before doing this kind of diet format.
Quite often cats have food anxiety, often from periods of food competition or just food scarcity. These food-anxious cats will eat all the dry-food in the bowl immediately. Some cats are so food-anxious, that they will eat to the point of vomiting, then continue eating after vomiting.
Grazer cats are not food-anxious, and will usually take small nibbles from the dry-food throughout the day. These cats are usually given one meal during the day to meet nutritional needs that their dry food may not provide. I've met these cats before, and they are able to stay a healthy weight without any negative health effects.
I think it's a very young puppy. Some big breed with fluffy hair? Like a Tibetan Mastiff or something similar.
EDIT: after some research, I think it's probably a Chow Chow puppy.
