Hello, and thank you for using Pet Coach. I am sorry to hear about Charlene, and I too am very worried. From her history, I would recommend that Charlene get checked out by a vet immediately. Since she is not yet nursing, it is unlikely that she is low in blood calcium (what causes milk fever), but it is still possible. There could be other causes for her odd behavior, including infection or other electrolyte abnormalities. After being examined by the vet, they will likely recommend bloodwork to see what is going on internally. You should also discuss with the vet if Charlene is on the appropriate dog food and nutritional supplements for her stage of pregnancy knowing her history of hypocalcemia. Dogs with a history of milk fever are prone to having it with each litter and you will need to be very vigilant once the puppies are born.
