There are many things in the dog's own nature, all of which belong to its own attributes, and today, when they live in densely populated areas of humans and live with their owners, their natures that contain wild factors are weakening or even disappearing one by one under the influence and suppression of their owners. But they have become genes and habit-forming behaviors that cannot be completely eliminated in a short period of time. Becoming pet dogs, their irritable and irritable personality is being changed by humans, and in the general trend, the temperament of dogs is developing towards meekness and obedience, which is exactly what people need. Therefore, the dog's living habits must meet the requirements of the owner, and their behavior must also change to the human side. Many masters have regarded them as family, but in fact, they can never be a member of the human race, and the master's ideas are only their personal hopes.

Dogs become pet dogs, and by the time they are modified by humans, they have actually changed a lot. They have consciously stopped barking loudly, and their desire to attack is gradually weakening. They have learned many human behaviors, such as human-like rituals, playing human skateboarding, and touching humans with their own behavior, etc. We don't know what a dog will look like in dozens or hundreds of years. But we don't doubt that dogs should have been closer to humans. We say that many of the dogs' instinctive behaviors are gradually changing, and even the random eating of that we have remembered as dogs for thousands of years has almost completely disappeared. It is this almost disappearing behavior, and the occasional occurrence is very unacceptable.
Historically, the most favorite thing people like to say to distinguish between wolves and dogs is that wolves walk thousands of miles to eat meat and dogs travel thousands of miles to eat. This is indeed an essential feature of both animals. Why do dogs eat? Is it fragrant? First of all, in the early days, dogs, in order to hide their tracks, would bury or eat their own excrement, which was a means of survival in the cruel natural world, and it was an act in their bones. In the period when they become human watchdogs, the owner is difficult to solve their food and clothing problems, they will go outside to find food, at this time hungry, they will eat everything that can be eaten. And some nutrients were left in the feces, and the owners at that time were accustomed to it, and even if they saw them eating, few people stopped it. In the eyes of people at that time, this was a very normal and reasonable behavior.
Today, when they become human pet dogs, they do not have a food crisis and a safety crisis at all, so there is no reason to eat again, and their disgusting behavior is bored by all owners. Dogs living with humans, their greatest psychological instinct is to do their best to be consistent with their owners and do not do as much as possible that makes their owners unhappy. They exercise self-restraint even in instinctive behaviors such as biting or barking, including eating. But just as they are emotionally unable to control their instinctive behavior, there will be occasional loud barking and aggressive behavior, and the act of eating also occurs inadvertently.
But the nature of pet dogs eating is fundamentally different from that of dogs in the past. Dogs themselves have some of the genes of wolves, including scavenger behavior. Substances that we think stinky have a certain temptation for dogs, and they will find out. Many owners forbid dogs to defecate in the toilet, so they use the time of walking their dogs to go outside to urinate. But when the owner has not returned home for a long time, the dog cannot hold back and is convenient indoors, and it will eat it for fear of the owner's punishment to eliminate the evidence of the crime, which is the credit of this kind of selfish master. Dogs may also eat grass, paper, or because of partial eating or pica.
Today's pet dogs should rarely eat feces, in short, I have not seen it. My family's bian mu is now four years old, and it has never behaved like this before. Because it has been cultivated since childhood to defecate in the toilet, we can just change the air in the toilet when we go home. The situation is different from family to family, even if it is a dog family, it will not be exactly the same. The dog's behavior of eating feces should happen occasionally, and it is not difficult to ask him to correct it. Because it has corrected many aspects since it entered the human family. It can be targeted to catch its current, severely punish its similar behavior, make the dog have a reasonable food mix, ensure its nutrition and so on. When walking the dog, it is strictly forbidden to stay in the garbage area, etc., are effective methods, and how to do it, the owner will have his own way.
In general, pet dogs now eat feces, mainly due to lack of nutrition or lack of related elements in the body. We must ensure that they will not lead to pica due to malnutrition, and usually pay attention to more communication and interaction with dogs to avoid excessive psychological pressure on dogs, which will have a good and effective effect on correcting their bad habit of eating.
