Dogs throwing up a lot before giving birth

Vomiting before delivery in dogs may be due to increased fetal activity, which in turn causes vomiting by squeezing the abdominal cavity. Usually the dog will show nesting and irritability before delivery, and will also show a continuous straining behavior. It is recommended that the owner closely observe the dog’s condition. If not, it may be due to the dog’s difficult labor, it is recommended that the owner promptly transport the dog to the veterinary hospital for Caesarean section, or time may lead to the death of the mother and puppies.
