Excessive salivation or excessive production of water at the mouth is normal in cats and dogs. However, if your pet is drooling excessively, or more than usual, it may be a sign of an injury. A quick look into your pets mouth for unusual objects, such a splinters, or wounds can help you to find the cause. If nothing is found, than it\'s advised to consult a veterinarian to determine the cause.
How to Recognize
While it is completely normal for dogs to drool - even cats can drool a little - some pets may suffer from excessive drooling, called hypersalvation, which can be a sign that something else is going on. Keep in mind it is normal for some dog breeds to drool more than others.
Heatstroke is the most common cause of excessive drooling. Excessive drooling can be a side effect of a stomach ache if your pet ate something inedible or even poisonous. Liver, kidney, mouth, or lung disease can also be the cause.
If your pet is suffering from heatstroke, immediately move him/her to a cool area and provide him/her with cool water. Dogs should drink one ounce of water per pound they weigh. If excessive drooling continues, seek veterinary care.
