Don't let it run less, jump less and move less, as it is necessary to keep warm in winter. My family is also a VIP. When the dog was born, the four of us took turns to look after it during the day and night, keeping our eyes on the dog's mother. We gave birth to four dogs, all of which were delivered by us. The third one was difficult to give birth because of its large size, but it was still too big to be born. The doctor dragged it out, or the bitch would be in danger. Now all three sons of bitches are fine. I suggest you observe carefully next time and be sure to send it to the hospital if necessary.
