Is Your Dog Sneezing? Here Are 6 Possible Causes

Table of Contents

Sneezing is normal for people, especially when they have an allergy, and the same can happen in dogs. The owners of these animals might worry when they see their pets sneezing, but this is something completely normal, so you should not worry.

Now keep in mind that if your dog is sneezing a lot and frequently, then it’s time to investigate what’s going on, as excessive sneezing can be a concern depending on the severity of the situation.

Is Your Dog Sneezing

It is important to know what is causing the sneeze to take the necessary measures. As we have already said, most sneezes are caused by allergies, and it is best to take the dog to the vet in these cases.

6 Causes of Sneezing in Dogs

While allergies are the main cause of sneezing in dogs, it’s important to understand that other factors could also trigger this reaction. The 6 main reasons for sneezing in dogs are:


Dogs can suffer from different types of allergies. Some are caused by environmental conditions, while others are caused by food.

Either way, allergy sneezing should be treated quickly if the canine suffers from a severe allergic attack.

These animals may frequently sneeze if the cause of that reaction is seasonal allergies. Keep in mind that depending on the time of year, more pollen and other particles in the air may affect these animals, causing them to sneeze constantly. 

In these cases, you must be prepared and have some medications (prescribed by the veterinarian) to combat your pet’s allergies during a certain season of the year.

On the other hand, food allergies are very common in both people and dogs. Generally, this type of allergy affects a dog’s digestive system, fur, and skin, although it can also influence how often it sneezes.

If your dog is fine but begins to sneeze excessively after eating, it may have eaten a food to which it is allergic. In that case, it is best to eliminate that food from its diet and replace it with another equally healthy and delicious one.

Your dog’s diet needs to be made up of high-quality foods rich in vitamins and minerals.

Upper Respiratory Tract Infection

Just like humans, dogs can also suffer from many types of infections. As we know, bacteria are the ones that generally cause infections in certain parts of the canine’s body.

These bacteria attack more easily (especially the respiratory tract) when a dog’s body has low defenses due to a contracted virus. Whether the infection is bacterial, viral, or fungal, it is important to note that they are all highly contagious.

If your dog is sneezing a lot, you should be aware of other possible symptoms such as cough, runny eyes, and nose, lethargy, etc. In that case, a veterinarian should check your pet to rule out any serious health problems.

Foreign Objects Lodged in the Nasal Passage

Dogs are very curious animals that try to explore everything within their reach. As they explore, they will sniff out all the items they find, but be aware that sometimes this can be a negative as some breeds might want to put such things in their mouths.

This usually happens when the canine finds pieces of broken objects on the ground in the garden or backyard. It could also ingest small toys which will lodge in the nasal passage causing a severe problem to the respiratory tract. If your pet has swallowed an object, don’t hesitate to take it to the vet quickly so he can remove the item inside.

Apart from excessive sneezing, a foreign object in the nasal passage can cause other symptoms in these animals, such as:

  • Runny nose
  • Swelling
  • Pawing at the nose

Nasal Tumours

Another cause of frequent sneezing in dogs is nasal tumors. As you know, any type of tumor can present a severe problem if they are not treated in time.

Keep in mind that a small tumor may not cause many symptoms, but as it develops and grows larger, it will become more problematic, causing excessive sneezing and breathing problems. Other symptoms due to nasal tumors are:

  • Runny nose
  • Wheezing
  • Cough

It is not so easy to get rid of nasal tumors. Sometimes the solution may be a simple excision, while in more severe cases, it will require chemotherapy.

Nasal Mites

Mites are microscopic parasites living in different places on a dog’s body, such as the ears or nose. Nasal mites can cause various nasal problems (some more serious than others).

Keep in mind that some dogs with nasal mites never show symptoms, but the problems could become serious in other cases.

Mites reach dogs when they rub their noses in the dirt. These little parasites will cause excessive sneezing in addition to:

  • Bloody discharge from the nose
  • Inflammation
  • Irritation
  • Itching

If you notice any of these symptoms, taking your dog to the vet might be the wisest decision. He will diagnose your pet and determine the seriousness of the situation. A veterinarian usually prescribes deworming medications.

Dental Problems

Believe it or not, dental problems can also cause sneezing in dogs. Obviously, this will not always happen, as it will depend on the seriousness of the situation.

Generally, infections in the roots of the teeth are triggers for sneezing. Other dental problems that can lead to excessive sneezing in dogs include:

  • Abscesses in the gums
  • Damaged teeth
  • Tumors in the mouth

The best option is to take your pet to a veterinarian specializing in dog teeth, and he will perform a dental exam to identify the root problem.
