are pregnant dogs aggressive

Pregnant dogs can indeed become more aggressive, particularly as they approach giving birth and when they are protecting their newborn puppies. This behavior is generally due to hormonal and physiological changes, stress, and strong maternal instincts to protect their vulnerable pups. Aggression can increase with irritability, territorial defense, and protectiveness during the late pregnancy and early postpartum period. This heightened protectiveness may also cause a pregnant dog to become more defensive or aggressive toward other dogs and strangers. This maternal aggression is usually temporary and tends to diminish around three weeks after the puppies are born, as the puppies become stronger and more independent. Providing a calm, safe environment and minimizing stress can help reduce aggression. If aggression persists or is concerning, consulting a veterinarian or animal behaviorist is recommended.
