In the early stages of pregnancy, dogs will stop going into estrus, like to be clingy, and are unwilling to let male dogs get close to them. Around the 30th day of pregnancy, the dog's abdominal circumference will become larger and the appetite for food will increase. At this time, it is recommended that the owner take the dog to the pet hospital for a B-ultrasound examination, which can determine the number and development of the fetus in the dog's body.

When the dog is 45 days pregnant, the breasts will be enlarged and the nipples will be pink. In daily maintenance, it is necessary to avoid strenuous activities for dogs to prevent miscarriage, such as jumping, going up and down stairs, running, fighting, etc. You can take your dog for a walk and get more sunshine.
