    Every dog owner finds themselves in a slobbery situation now and then, but if your dog drools a lot you might find your patience wearing thin. Several possible reasons for excessive dog drooling exist, but it's vital to rule out any medical problems first of all.

    If your dog is drooling a lot more than he usually does, it could be caused by an underlying illness or injury. A range of medical reasons can cause your dog to drool excessively, including mouth abscesses, dental problems, foreign objects in the mouth, distemper and infection of or damage to the salivary glands. Consult your veterinarian right away if you suspect there could be a medical reason for your dog's drool problem.

    In a healthy dog, drooling is most commonly a result of hypersalivation -- or an increase in saliva production by the salivary glands -- in response to a stimulus. More often than not, this stimulus is food. Dogs, like people, produce extra saliva to digest their food so the simple anticipation of getting food can cause a slimy response. If you routinely feed your dog from the table when you're eating meals or having a snack, he'll expect food each times he sees you eating. Stop feeding your pup while you're eating and his drool issues are likely to calm down.

    Psychological factors can be another cause of your dog's hypersalivation. These include anxiety, fear or apprehension. Ideally, your dog shouldn't feel anxious or fearful on a regular basis, so you should aim to stop exposing him to anything that triggers these responses. Your dog may also drool a lot when he's excited, so you might notice extra saliva when he's about to go for a walk or when you return home after a period of absence.

    While there's usually a reason for a dog's excessive drooling, the fact of the matter is that some dogs are just naturally more slobbery than others. Breeds with loose jowls or large, pendulous lips have more of a propensity toward drooling than other types of dogs. Breeds that are known to be prolific droolers include Saint Bernards, bloodhounds, mastiffs and Newfoundlands. If your dog is a born drooling fiend, there's not much you can do but waterproof your valuables.
