It is common that puppies born by dogs fight with bitches every day. This is usually caused by the competition between puppies and the education mode of bitches.

In the social world of dogs, the law of the jungle is a very common behavior. Puppies are also competitive. They will compete for the best food, the best location and the best resources. In this process, fighting is a very common way. This behavior also helps them to establish social order and find their place in society.

Bitches often fight to educate their puppies and let them learn how to be strong dogs. In the natural environment, the bitch will help the puppy to establish a strong individual identity through early education. Therefore, fighting is common among a group of puppies educated by bitches.

However, if the bitch is too strict, or some puppies with abnormal behavior are not fully integrated into the social order, this fighting behavior may get out of control slightly, leading to some problems. At this time, pet owners need to pay close attention to the dog's behavior and consider taking some intervention measures to prevent excessive fighting behavior.

In a word, it is normal for puppies born by dogs to fight with bitches every day, which is part of the competition between puppies and the education of bitches. If the bitch is over-educated or has puppies with abnormal behavior, it is necessary to intervene in time to avoid excessive fighting behavior.
