1, it's hard to be sick.

Dogs often stretch in front of you. If the expression is a little painful, it is probably uncomfortable. They feel uncomfortable, but there is no way to solve it, so they can only ask their master for help. If the dog doesn't get better in a few days, it's time to take it to the doctor. Don't delay.

2. Greeting you.

When dogs meet other small animals or want to interact with someone, they will stick out in front of each other, which is a bit like inviting them to play. Some dogs may be challenging another dog, which is really embarrassing.

3. Unhappy

If a dog sees someone he doesn't like, or something he is afraid of, he will enter a state of vigilance, making his upper body kneel and his lower body arch, ready to attack at any time.

4. wake up and stretch.

The dog sleeps late on the ground. After they get up, they will stretch their bodies and exercise their muscles to start a new day. Dogs behave like this. In fact, we humans just look a bit like each other when we get up. Sometimes dogs may imitate humans.

My stomach is a little full.

Dogs are greedy and sometimes eat more when they see delicious food. Dogs will do the same action as stretching when they have indigestion, which can promote the digestion of food.

The owner can touch the dog's stomach to see if it is hard. If it is too full, he can rub the dog.
