Dog slobber is a normal part of being a dog parent … right? While dog slobber is — in most cases — an ordinary occurrence, there are some unique instances when too much dog slobber might indicate a medical issue.
So, how can pup parents tell the difference between what’s normal dog slobber … and what’s not? There are a few things that may play a role in the amount of dog slobber your pup produces — like his breed, excitement over a toy or food or a medical ailment. Here’s what you need to know about dog slobber!
First, how often does your dog slobber — generally? If you seldom notice your dog drooling and then all of a sudden over a two-day period, you notice an intense amount of increased dog slobber, that’s something to take note of. If your dog’s slobber levels have drastically changed, alert your vet.
“Ptyalism is the medical term for the excess production of saliva,” explains Dr. Seth Bynum, DVM, who documents his veterinary adventures on Instagram at @birddogvet. “Most owners are going to know their dogs well enough to determine when the production of saliva is excessive, so if I see a lot of drooling in the exam room, I always ask if this is a normal amount for their dog.”
Dog slobber is normal in all breeds, though some exhibit it more physically than others. Breeds like Bloodhounds, Newfoundlands, Saint Bernards, Mastiffs and Bernese Mountain Dogs have reputations for being particularly drool-y. If you have one of these breeds of dogs, then a significant amount of dog slobber is probably normal. More on that later!
Does your dog slobber while anticipating something exciting? (Like a treat, food or maybe a toy?)
“I have Labradors and they drool often in anticipation for eating, playing or retrieving,” says Tracey Jensen, DVM, Dipl. ABVP, medical director at Wellington Veterinary Hospital in Wellington, Colorado. “That drooling is a part of their personalities. It’s something they’ve always done, it’s infrequent and it correlates with something they’re anticipating.”
Things like holding a tennis ball above your dog’s head or preparing her food over the counter might make her drool. Why? Because she’s gearing up for something that makes her happy. If she knows you’re about to throw a toy for her to retrieve or place food in her bowl, then she’s likely to get excited. Hence the drool!
“Most owners will be familiar with drooling when their dog is hungry, or as a natural response to the sight and smell of food,” continues Dr. Bynum. “The saliva aids in swallowing and provides some early enzymes utilized in the digestive process.”
The above are examples of normal dog slobber. However, there are some cases in which dog slobber indicates something else going on entirely. Some dogs may drool when they are anxious, even if they are not regular, frequent droolers. If your dog’s drooling is coupled with another one of the symptoms associated with anxiety — dilated pupils, excessive panting and tensed muscles — then your dog might be stressed.
If the dog slobber is due to anxiety, the drool (and the anxiety) will likely discontinue once the stressor is removed. Typical stressors include the adoption of a new puppy, a thunderstorm, the introduction of someone new, home renovations or another new change.
“In the clinic, the most common time I see excess drooling is when dogs are nauseated. Owners will tell me they haven’t seen their dog vomit, but the drooling is a dead giveaway that they really feel like puking,” says Dr. Bynum. “This is a common clinical sign in dogs with car sickness. Another common cause is mouth pain, and the excess saliva is often accompanied by the sudden onset of halitosis, or really bad breath. Dental disease, wounds in the oral cavity, broken teeth or jaws, and foreign bodies like sticks or toy parts lodged in the mouth will trigger these hypersalivation episodes. Occasionally, dogs will hypersalivate with exposure to toxins, and the hypersalivation will be accompanied by other clinical signs, such as excess tearing, dilated or constricted pupils, inappropriate urination and diarrhea.”
“It could be a sign of a neurological condition, in which the nerves in the face don’t work, or a blockage in the esophagus caused by something like a bone,” explains Dr. Ann Hohenhaus, DVM, DACVIM, a veterinarian at the Animal Medical Center in New York City.
Drooling is usually only a medical concern if it is paired with other symptoms. If your dog appears hot, is excessively panting, won’t eat, is vomiting or experiencing diarrhea, consult your veterinarian immediately.
Keep a watch on what your dog is eating. Oftentimes, if a dog gets into something he shouldn’t — like the trash! — an indigestible object might cause tummy upset. In turn, it can cause some excessive dog slobber.
Likewise, make sure not to keep any plants around the home that are noxious to dogs. When dogs suffer from an allergic reaction to a poisonous plant, they may drool excessively and then get sick. Keep dogs away from pine needles, holly, poinsettia, lilies, chrysanthemum and more. Read more about poisonous holiday plants for dogs and plants in your garden that might be toxic to dogs.
If the dog slobber is due to anxiety or sickness in the car, mitigate this by acclimating your pup to the car. Work your way up to driving your dog around the block.
Brush your dog’s teeth! Sometimes, excessive dog slobber indicates periodontal disease or an abscess. But these are easy ailments to prevent. All you have to do is brush your dog’s teeth at least once a day.
As noted, dog slobber is sometimes a natural way of life for pups. Mostly, it’s in their biology as in, the way dogs’ mouths are shaped. Dogs’ mouths also have mucous membranes in their mouths and the biological reason for saliva is to moisturize those membranes. With a whole lot of spit and not many places for it to go (not to mention a loose upper lip), it’s no wonder a lot of it ends up pooling around their mouths or on the floor!
“Saliva pools in their cheek pouches, and when they shake their heads, the drool flies,” says Dr. Hohenhaus.
As mentioned previously, some breeds are just predisposed to dog slobber. This includes breeds like Bloodhounds, Newfoundlands, Saint Bernards, Mastiffs and Bernese Mountain Dogs.
Short-nosed or brachycephalic breeds are sometimes susceptible to drool as well. This is because they are more likely to get heat stroke, which can cause slobber in pups. These breeds include Boston Terriers, Boxers, Bulldogs and Pugs.
“Some breeds are prone to slobber based on their conformation,” explains Dr. Bynum. “Owners who are drawn to those breeds don’t have much recourse for preventing it, rather they just need to embrace it as part of owning that particular breed.”
If you have one of the aforementioned breeds, make sure to note their regular drooling habits and alert your veterinarian if anything changes drastically and over a short amount of time.
