Mother dogs will always know their babies. Dogs have much more advanced senses than humans. They have a very sensitive sense of smell and can smell many odors that humans cannot detect. After the puppies are born, the mother dog will remember the special smell of the puppies, which humans cannot smell. Dogs can recognize their babies based on this special smell.

Methods to appease a dog mother after her child is sent away:

1. Interact more. Owners should pay attention to the dog's emotional changes, as it may cause depression. Don't let it stop eating or drinking. Touch it more and tease it more. Try to stay with it and "interact" with it as much as possible.

2. Show more love. After the puppy is gone, clean the place where the puppy has been to avoid leaving any smell. You can also give the puppy-like toys to let the dog's mother "take care of" and let it "empathize with others."

3. Be more understanding. The owner must understand the behavior of the dog during this period, which may include whining, being aggressive towards people, etc.

4. Exercise more. You can take your dog out for a walk in the park, go out for more walks to distract your attention, and you can also reward your dog with some small snacks appropriately.

5. Improve your diet. You can usually add some pet goat milk powder to the dog's food to increase the dog's appetite.
