Chihuahua
We all know that dogs are very friendly animals, but it is not difficult for us to do so in life. I have encountered many dogs that become aggressive when they see strangers. Why is this?
Playing with people is a natural habit for dogs, but its level often depends on the level of "marks" of contact with people at 3 to 7 weeks of age. If a dog is only with its parents or other dogs in the first two months of its life, and not with people, or does not really get to know people gradually, it will be separated from people throughout its life and will be difficult to train. If it is caressed by people since birth, it will realize that people are friends and can play with it. It will also become familiar with people's breath, be kind to people, and easily accept training. It is very important to pay attention to its marking stage when selecting and training a dog.
