The symptoms of a dog in the early stages of pregnancy will not be very obvious, generally when the dog is 20-30 days pregnant, the nipples will be slightly red and swollen, activity decreases, and appetite is high, but some dogs may have a reaction to pregnancy vomiting and show symptoms such as loss of appetite, depression, lethargy, etc. Of course, to determine whether a dog is pregnant, most of them need ultrasound to make an accurate judgment. If the dog is 40 days pregnant, the symptoms are more clear, such as abdomen obviously bulging, swollen and red nipples, from time to time secrete a small amount of milk, and appetite will increase significantly, about 20% more than usual, during this period the owner will need to give the dog supplemental nutrition, especially calcium and vitamins.
