The most obvious prenatal signs of English Bulldogs are shortness of breath, anxiety and irritability, thirst and drinking a lot of water, walking back and forth, vomiting, burrowing, etc., and the amniotic fluid will begin to break half an hour before the dog is born, and dark green secretion will flow from the lower body. The dog's nipples can also express milk, which means the dog is about to give birth. British bulldogs are small dogs, but they are relatively round, so the puppies will be fatter than ordinary small dogs, and there will be a certain chance of dystocia, so it is best for the owner to observe from the side.
