Why Does My Dog Sneeze When I Kiss Him? Explained

Dogs are known for their adorable and quirky behaviors, and one such behavior that often leaves dog owners puzzled is when their furry friends sneeze in response to a kiss. 

While it might seem strange or amusing, there are several reasons why dogs sneeze when kissed. In this article, we will explore the possible explanations behind this peculiar behavior and shed light on whether it’s a cause for concern.

Instinctive Response

One possible reason why dogs sneeze when kissed is due to an instinctive response. 

Dogs have a highly developed sense of smell, and when we get close to them, our breath carries a range of scents and foreign particles that may irritate their sensitive noses. 

This can trigger a sneeze as a natural reflex to expel the irritants and clear their nasal passages. It’s important to note that this response varies from dog to dog, and not all dogs will exhibit this behavior.


Another reason why dogs may sneeze when kissed is due to overstimulation. Dogs are highly social animals, and they express their emotions in various ways. 

When we shower them with affectionate gestures such as kisses, it can be overwhelming for some dogs, particularly those who are sensitive or easily excitable. 

Sneezing might be their way of expressing excitement or a response to the stimulation they are receiving. It’s similar to how some dogs wag their tails vigorously when they’re happy.

Contagious Behavior

Dogs are known to be keen observers and imitators of human behavior. They learn from their surroundings, including our actions and gestures.

If you sneeze frequently or make a certain noise before kissing your dog, they may develop an association between that sound and the upcoming kiss. 

Consequently, when they hear that sound, they might preemptively sneeze in anticipation of the kiss. This behavior is a result of their ability to mimic our actions and their desire to participate in the interaction.

Sensitivity to Perfumes or Cosmetics 

Sometimes, the cause of a dog’s sneezing when kissed can be attributed to external factors. Dogs have an exceptional sense of smell, and if their owners use perfumes, lotions, or other scented products, it can trigger a sneeze. 

Dogs have different sensitivities, and certain scents can be overpowering or irritating to their sensitive nasal passages. 

It’s advisable to avoid applying strong-smelling products before interacting closely with your dog, as it may cause discomfort and sneezing.

Underlying Health Issues

While most cases of sneezing when kissed are harmless, there are instances where it could be indicative of an underlying health issue. 

Dogs can suffer from allergies, respiratory infections, or nasal irritations that can cause sneezing. 

If your dog’s sneezing is persistent, accompanied by other symptoms such as coughing, discharge from the nose or eyes, loss of appetite, or lethargy, it’s crucial to consult a veterinarian for a thorough examination. 

A professional assessment will help rule out any health concerns and provide appropriate treatment if necessary.


Dogs sneezing when kissed can be attributed to various factors, including instinctive responses, overstimulation, imitating human behavior, sensitivity to scents, or underlying health issues. 

Understanding why your dog sneezes when you kiss them can help you determine if it’s a normal behavior or if further investigation is needed.
