7 Reasons Why Your Dog Is Drooling Too Much and Why You Should Be Worried
Why Is My Dog Drooling?
Has your dog started to drool a lot? If your dog does not normally drool a lot but has started drooling everywhere, find out what is wrong and what you can do about it.
Excessive drooling is one of the worst problems for some dog owners. Every time the dog goes to the water dish, they leave a mess, and a dog with facial hair is that much harder to clean up after. If you bought a drooler like a St. Bernard, you might have known what you were getting in for, but if your dog was never a drooler before, there might be something you can do about it.
Reasons Your Dog Might Be Drooling a Lot
- Foreign body in the mouth
- Dental problems (like an abscessed tooth)
- Nausea or painful abdomen
- Cancer in the mouth
- A contagious disease that does not allow him to swallow—think Rabies First!
- Other less common causes, like a portosystemic shunt, myasthenia gravis, polymyositis
Other Signs to Look Out for in Addition to Drooling
Some of these things may have been going on for a while and you have not noticed them or just figured they were a normal part of a dog's life. Pay attention!
- Bad breath
- Weight loss
- Sensitive to touch around the mouth
If you have looked at the reasons your dog might be drooling excessively, you have noticed that some of them are serious, but many of them are nothing to be worried about. But if your dog is drooling because of cancer, and you let it go for a few weeks, there may be no way to save him. And do you really want a dog with advanced rabies running around your house? Unfortunately, you need to find out what is causing the drooling and fast.
Some of the Tests That Your Vet May Need to Run
- Exam under anesthesia to look for any lesions: Some of these causes will make a dog very sensitive under examination and the only way to find out what is wrong is to do an exam while your dog is under sedation.
- Neurological exam
- CBC or a complete blood count to determine if there is an infection
- Screen for poisons
- X-rays: If your dog has a tumor, for example, it may appear small but if it has invaded the jaw or sinuses it will not do much good to just remove it.
- Serum biochemistry
- Urinalysis to look for metabolic problems
- Abdominal ultrasound if your dog is feeling nausea but the cause cannot be determined
Possible Treatments for Excessive Drooling
This will really depend on the cause, but do not assume this is going to be something that you will not be able to treat.
- Remove a lodged stick or other foreign object from the mouth
- Extract an abscessed broken tooth
- Treat an infectious disease with antibiotics
- Remove a tumor from the mouth
Schedule a Visit With Your Vet Now
If your dog has a stick lodged in her mouth, a broken tooth, or is just salivating a lot because of something she ate, you should schedule a visit with your regular vet now and help her feel better. This drooling problem can clear up right away or in a few days and your lives can return to normal.
Some dogs have a more serious cause, of course, like cancer growing in the mouth, but the sooner you take your dog in the better her chances of recovering. Get them in today. If your regular veterinarian cannot schedule an appointment for your dog take her to an emergency clinic . . . it may be worth the extra expense.
Some tumors in the mouth are easy to remove. If you do not take care of it right away, however, your dog can end up like this (pictured below). This case of excessive drooling can be treated at home.

Questions & Answers
My 2 yr old dog just started having a lot of saliva come out her mouth out of nowhere and she never ever drools or anything. Should I be worried about my dog's excessive saliva? This is the first time this has happened.
Your dog may have a foreign body (like a stick) lodged in the throat. Take him to your regular vet for an exam as soon as possible.Helpful 62
My 4-year-old lab has had loose stools for the past two days. She's started drooling heavily and is restless; she's also refusing water and food. She does sometimes eat apples on the ground from our apple trees. This behavior is unusual for her. Any idea what's going on?
There are several possibilities. She may just be having a mild reaction to the fruit because of the sugars. I do not know why she is restless unless it is because of the stomach ache. There is also a possibility she has eaten enough apple seeds to make her sick. They are poisonous if many are consumed.Helpful 31
My 10-month-old Irish terrier has had clear, grayish discharge from his eyes for a month. Now he is very sad, has slowed down, has bad breath, and a couple of days ago his mouth got wet, as though he just drank water. What's wrong?
If your puppy is depressed and moving around slowly at this age, then there is a serious problem. He needs to be examined by your vet. He may have a foreign body in the mouth, organ failure (like a kidney disease), or a systemic infection. I cannot tell you what exactly is wrong without an exam and bloodwork.Helpful 29
My dog has recently just started drooling in his sleep, his beard is always soaked. I don’t know if it’s because of the hot weather or not but he’s never been one to drool. He is a pure bread havanese and has been throwing up not regularly but a few times in a month. Is this serious?
Although you do not indicate what age your Havanese is, the most likely problem with excessive drooling in this breed is dental problems. It would also account for the periodic vomiting, since if he is swallowing a mouthful of pus from time to time it will upset his stomach.
Get him checked out as soon as possible. The vet can look at his teeth, feel for any loose ones, but may have to do an x-ray to look for infections deep in the roots.
He may also need to be put on antibiotics before the procedure.Helpful 23
My dog just started to express a lot of water from his mouth. It isn’t thick drool. It’s like he’s just come from his water dish with water in his mouth. What might be the cause?
Some dogs will have very thin saliva, so any of the reasons in the article (foreign body in the mouth, etc.) are a possibility.
It is also possible that the water coming out of his mouth is a very thin vomit. The most likely reason for a very thin liquid like you describe is a toxic plant or grass. You can read https://pethelpful.com/dogs/my-dog-is-vomiting for more possibilities and try to hold off on food to see how he does. However, if this continues, you are going to need to take him to your regular vet for an exam.Helpful 2
