If the net profit of a dog is 1 000, then you can earn 1 000 by raising 1 000 dogs. But the dog market has been unstable, because we can't control the number and appearance of each bitch, and some dogs will die, so we have to practice how many dogs can earn 200 thousand.

Dogs need to be provided with sleeping nests, eating bowls and toys. Dogs need training since childhood, such as defecation, and their owners need patience. Vaccinate dogs on time to drive away insects inside and outside the body. Feed the dog food and water regularly every day. Pay attention to the dog's physical condition, such as vomiting and diarrhea.
