The reason why dogs stick out their tongues after giving birth is because dogs have no sweat glands and can only dissipate heat through their tongues. Owners can prepare cooling pads and clean water sources for dogs to lower the temperature. The dog's body is particularly weak after giving birth. During this period, you should pay attention to supplementing the dog's nutrition, or take the dog directly to the pet hospital for infusion to supplement calcium, so that the recovery effect will be more obvious.
