Reasons Why Your Dog’s Excessively Drooling in Wilmington, DE

In this article, we’ll walk you through some of the most common causes of drooling in dogs. Some of these are less serious than others, but no matter what you might think the underlying cause is, be sure to take your dog to the veterinarian in Wilmington, DE if you have any concerns about her health.

Reasons why your dog’s excessively drooling include, but aren’t limited to:

Injuries and Foreign Objects

Sometimes, dogs may injure their mouth or gums, which can lead to excessive drooling. If your dog has any type of injury in or around her mouth, this could be the cause of the drooling issue. When the injury clears up, the drooling should go back to normal as well.

Foreign objects that become lodged in your dog’s mouth can also cause this problem. Check your dog’s teeth, gums, and tongue for splinters, pieces of broken toys, or trapped pieces of kibble that could be causing the issue.

Dental Disease and Problems

Dogs with dental disease and gum disease often develop frequent drooling problems. They usually have other symptoms as well, including bad breath and visibly damaged or blackened teeth and gums. A vet in Wilmington will need to assess your dog’s dental health and ultimately treat this problem to clear it up.

Dogs may also have other dental problems not related to disease, such as a chipped or broken tooth, missing teeth, and other similar issues. In these situations, your vet can give you some suggestions for how to help, but some of these problems may not have a treatment.

Anxiety and Fear

If your dog’s drooling comes on suddenly and is in response to something that is or could be making her nervous, then the problem is likely anxiety. Dogs drool a lot when they are exceptionally anxious, such as at the vet’s office, in the car (for some dogs), or around other animals or people they don’t like.

Dogs who are afraid may also have the same response. Fireworks are a common cause of excessive drooling in dogs who are scared. If the drooling eases up when your dog relaxes once again, this is likely the cause, and it may not require veterinary intervention.


Dogs who are suffering from heatstroke may start drooling as an early sign of this problem. If your dog has been exposed to high temperatures and begins drooling excessively, take her indoors to an air-conditioned space and give her plenty of fresh, cool water to prevent the problem from getting worse.

If you notice signs that your dog’s heatstroke is getting worse, take her to an emergency vet immediately. She will need treatment with IV fluids right away to prevent the heatstroke from becoming fatal, as it can quickly dehydrate dogs to severe levels.

Liver and Kidney Disease

Liver and kidney disease both cause excessive drooling as they progress. Although this may not be the first warning sign of either of these problems in your dog, it is some of the earliest. Because of this, it’s important to take your dog to the veterinarian in Wilmington for bloodwork if you notice her drooling a lot without any visible cause.

Liver and kidney disease are usually irreversible in dogs, but they can be managed. Many dogs can live a long time with a good quality of life while keeping up with appropriate management measures prescribed by the vet for both liver and kidney disease.

Oral or Nasal Tumors

Dogs who have tumors in the mouth may develop excessive drooling as a symptom. If your dog has a tumor in her mouth, you can likely see it if she will let you get a good look at her mouth. Some dogs, however, may not let their owners do this.

Nasal tumors can sometimes also cause drooling. This is less common than drooling from oral tumors, but it can still occur. You may or may not be able to visually recognize a tumor in or around your dog’s nose. For either of these problems, vet care is required to treat and manage them.

Now that you’ve had a chance to read up on some of the causes of excessive drooling in dogs, you may be more prepared to talk to your dog’s vet about her drooling issue. Your vet can give you more information and guidance toward figuring out the cause and treating the issue, too.

Most of the time, excessive drooling isn’t anything to worry about, particularly if you your dog is a breed known to drool a lot.
