We have a pitbull that just dropped a puppy and buried it still in the sack. ,she is only 55 days at most. its been 3 hours and she shows no signs of labor.will she have all of them now or can she still carry the rest full term.? I mean is it normal to have only 1 pup now and the rest in a week? or once it starts they all come? I will call the vet when it opens, but she acts like shes not even in labor except the dark blood that leaks out.
