If the youngster was raised with a mother that was not normal, who herself had perhaps been raised abnormally, the youngster would become more aggressive as a direct consequence of the aggression that it received from its mother. As a consequence, some people recommend not feeding their animals every day of the week, and it's quite common now for animals in zoos, such as lions and tigers, not to be fed for one day of the week. This would probably be more likely to be the case if they were fed in the same way that wild animals would be fed, which means large amounts at one sitting and then not fed for a couple of days. Lions, for example, would eat large amounts and then other scavengers would eat the food and they would be unlikely to feed again for a couple of days until they hunted again. A similar thing is probably true of dogs.
Dogs are also scavengers.
One of the biological adaptations to that is that in humans if meat is allowed to remain at room temperature for a period of time, various bacteria get into the meat and some of the bacterial excrement is highly toxic. Food-poisoning is often caused by botulina toxin. It's the excrement of the botulina bacteria which survives in meat which is in conditions where there's no air. That's why when they say when you put meat in the fridge, you should loosely wrap it so that the botulina toxin which is floating around in the air does not grow well. The botulus also doesn't grow well under low temperature conditions, but if you have meat which is at room temperature, such as some cooked meats, and it's there for a while, it grows, feeds and multiplies and excretes well.
