Influenced by past training

When dogs are young, owners will train them to urinate and defecate at fixed points, and reward the dogs when they do it right. Although they have developed habits when they grow up and no longer need to train them specifically, the memory of their childhood still remains in their minds, so that when they poop, they will look at their owner, as if asking: "Poop here" Can you?", "I'm doing the right thing, praise me!", "Am I awesome! Give me a reward! Woof!".

Following you means trusting your performance

Unlike cats, dogs will go to the toilet in hidden places to reduce the chance of being attacked. They usually find a place they like and squat down to free themselves, so they often become obvious targets. Because of this, when they go to the toilet and look at you, they are actually saying: "Hey! Check to see if there is any movement behind you!"

Dogs have a concept of privacy

If you defecate on them If you stare at it when you need privacy, it will also think that this privacy boundary can be crossed. This may explain why pet dogs like to enter the bathroom when you use the toilet, and follow you when you do things in the room. Come in.
However, regardless of the actual reasons, one thing is unquestionable, that is, they all regard you as the most important and trusted leader. We still have family, friends and other emotional relationships, but to them, we are the only ones in their lives, which is an absolute love and trust.
