Dogs sneeze due to various reasons. They sneeze when they feel excited and want to communicate and also when they have a serious health condition that needs medical assistance.

Since you can’t differentiate between a playful and a severe dog sneeze, it is important to understand why your dog might be sneezing.

Why is my dog sneezing continuously?

If your dog is sneezing or trying to blow air out of its nose continuously, look for the reason that triggered it. While there is not much to worry about until your dog starts to show other signs of discomfort, you can always call your dog’s veterinarian for an expert’s opinion.

Causes of sneezing can be anything ranging from playfulness to nasal tumors.

1. Allergies in dogs and sneezing

If you are wondering why your dog sneezing, it could be an allergy attack. Much like humans, dogs can start sneezing when they have an allergic reaction.

Allergy in dogs can be triggered by dust, mold, pollen, flea bites and even from certain kinds of food. Sneezing from an allergic reaction is accompanied by other symptoms as well. If you notice that your dog is itching all over the body or just one particular spot, and is wheezing or coughing, then allergy is the cause of sneezing.

Treatment to stop sneezing caused due to allergy

In case your dog is sneezing constantly due to an allergic reaction, you can talk to your dog’s veterinarian, and get anti-allergic medicines like antihistamines that can stop the sneezing.

Try to keep your dog away from anything that triggers an allergic reaction.

Breeds that are prone to allergy

Some breeds are predisposed to developing allergies more than others. These include Boxers, Dalmatians, Labrador Retrievers, Golden Retrievers, Shih Tzus, and Lhasa Apso. Other than these breeds, other dogs too may develop allergic reactions to different things.

2. Foreign particles in dog’s nostrils

Constant sneezing can be a sign that some foreign matter might have entered your dog’s nostrils. Anything like a strand of hair or grass inside their nasal cavity may cause your dog to sneeze uncontrollably.

You may notice that your dog is showing signs of discomfort if the sneezing is due to foreign particles inside the nostrils.

Along with sneezing, your dog will rub its nose on the ground or rubs its paws around the nose.

If you suspect that there might be something trapped inside your dog’s nasal cavity, call your dog’s veterinarian at the earliest. Only experts can successfully access the situation and location of the foreign particle in the nasal cavity and extract it without the risk of getting it further inside the nose.

The best way to prevent your dog from sneezing due to foreign particles is to keep your house clean. Keep a close eye on your dog when he goes outside.

3. Airborne irritants and sneezing

Dogs also sneeze due to airborne irritants. A strong perfume smell or smoke can cause a sneezing fit in your dog. To avoid this, try not to use strong-smelling perfumes or cleaning agents while your dog is around.

Dust and pollens can also cause your dog to sneeze. Keep your house clean and during springtime try to keep your dog indoors to avoid sneezing triggered by pollens.

Though your dog’s sneezing fit that is set off by inhaling airborne irritants is not fatal, you need to remove the offending irritant as soon as you can.

Keep your house clean and avoid smoking around your dog. During summer bonfires, keep a watch on your dog so that they are not too close to inhaling the smoke.

4. Nasal infections in dogs

Nasal infections in dogs often lead to sneezing constantly. Sneezing caused by bacterial, viral or fungal infections continues for more than 2-3 days or until the infection has been treated properly.

The other symptoms of an infection in your dog’s nasal cavity are loss of appetite, discharge from the nose accompanied by blood and coughing. If you notice any such symptoms in your dog, consult your veterinarian.

Sneezing caused due to nasal infections in dogs can only be stopped when the infection is eliminated. Visit your dog’s veterinarian and get medicines that can make the symptoms of the infection less severe and eliminate it completely.

5. Sneezing in dogs caused by playfulness

Dogs use all of their bodies to communicate. Sneezing is just another of the many ways they communicate.

Dogs sneeze while they get excited during their playtime. While playing with friends or chasing birds outdoors, you can notice dogs sneeze. This kind of sneezing is not from the lung but the nose and they do it to show their excitement.

This kind of sneezing should not be a cause of worry at all. In case your dog is outdoors, just keeping an eye is good enough.

6. Causes of sneezing that needs quicker and more serious attention

If you have been paying attention and the sneezing in your dog is not due to allergic reactions, airborne irritation, nasal infection or play, it may be caused by a nasal tumor.

This is more common in older dogs. Sneezing caused by tumors is often seen accompanied by nasal discharge, lack of appetite, and sudden weight loss.

The treatment of tumors depends on their type and location. Your dog’s age and health conditions also play a crucial role in determining the type of treatment path taken. Consult your dog’s veterinarian and get a treatment plan ready as soon as you can to prevent the tumor from increasing in size.


No matter the reason why your dog is sneezing, if it’s not due to playfulness, it’s always better to consult your dog’s veterinarian to rule out any chances of an underlying cause of sneezing.
