A
I have raised dogs for many years. I’ve found out what they want and given it to them.
When you get a new puppy, like a small baby, its personality is already somewhat established. It may be a “screamer” or a “cuddler (搂抱型)”or a quiet dog or an energetic dog. All puppies need sleep in massive (大量的) quantities. An energetic puppy will run around and suddenly fall down sound asleep. A quieter puppy will start to show signs of tiredness, then find a place to fall asleep. A “screamer” will scream for attention: Puppy cries and yelps（狗吠）, while a quiet puppy will usually give up and accept being put in a box. A “cuddler” will need your body, either your lap or next to you, to sleep soundly.
Puppy language is very simple. It is like a baby’s cries. They cry when they are in need or in pain; in need of company, in need of food, in need of sleep, etc.
As your dog grows, you should learn what they are saying to you, as they learn to take their cues(暗示) from you. If you rub（揉） your puppy’s stomach, and he likes it, he will learn to roll over and “ask” you for a stomach rub. Almost all dogs will “ask” to go out. In some cases, this consists of standing or jumping at a door. If you ignore this request, your dog will make it again, more firmly.
