Why do dogs always sneeze and have a runny nose?

The dog sneezing and runny nose may be the weather. In cold winter, the temperature difference between indoor and outdoor is large, which is easy to cause dogs to catch a cold. At this point, the dog's immune system will decline, leading to the growth of viruses and bacteria, which will lead to sneezing and runny nose. In addition, some dogs have symptoms similar to allergens such as pollen and dust.

2. Dietary reasons

Dog's diet may also cause sneezing and runny nose. Some foods, such as spicy food and acidic food, may cause allergic reactions in dogs, which may lead to sneezing and runny nose in dogs. In addition, foods containing too many additives and pigments may also affect the health of dogs, leading to sneezing and runny nose.

3. Environmental reasons

The dog's environment may also be the cause of sneezing and runny nose. In the dog's environment, if there is more dust, smoke and odor in the air, it may stimulate the dog's nasal mucosa, leading to sneezing and runny nose. In addition, if the dog is in a damp and dark environment, it is easy to breed bacteria and viruses, which will cause sneezing and runny nose.

4. Other reasons

In addition to the above reasons, there are other factors that may also cause dogs to sneeze and have a runny nose. For example, dogs may have long-term physical problems, such as low immunity and severe allergic reactions; In addition, if the dog is in a state of mental stress and excessive pressure for a long time, it is easy to cause similar symptoms. These causes need to be examined and diagnosed by doctors before the specific causes and treatment schemes can be determined.
