“Cats rule and dogs drool.”In the 1993 movie Homeward Bound: The Incredible Journey, Sassy the cat stated, "Cats rule and dogs drool." A lot of dog owners may not agree with the first part of that statement, but even dog lovers have to admit that some dogs do drool. Drooling is probably one of the reasons many people don't like dogs. Even those who love dogs for their unconditional love, loyalty, wagging tails, and 101 other wonderful characteristics, say, "Gosh, I love it when I get slobbered on by my dog." What is drool anyway? Dog drool or slobber is just an excess of saliva. All healthy dogs produce saliva. It moistens food (making it easier to swallow) and is the start of the digestive process. But there's normal saliva and then there's buckets of saliva. So what causes the excess drooling?
BreedDogs that were bred to have loose lips are notorious for excess slobber. Saint Bernards, Bloodhounds, Coonhounds, Newfoundlands, Boxers, Mastiffs, and some Spaniels are among the breeds that may drool frequently. Staying away from these breeds doesn't guarantee you a slobber-free dog, nor will your dog necessarily be a drooler if he belongs to one of these breeds. Just be aware what you might be getting into if you do get one of these dogs.
Excitement or Anxiety TriggersRestaurant chains, food preparation shows, and recipe writers routinely use "mouth-watering" when talking about food. If your dog's drool floodgates open when you're fixing his meal, he's just looking forward to that bowl of awesome. What's more, your dog may concentrate so hard on watching you fix that delicious meal he forgets to swallow, which make the excess saliva cause more of a mess. Riding in a car may make your dog drool, especially if he associates car rides with something unpleasant (like going to the vet), if he suffers from motion sickness, or both. Anxious dogs will often pant or breathe with their mouths open, both of which can make them drool. Motion sickness can cause your dog to feel nauseated, which can also lead to excess saliva.
