Causes of sneezing in dogs:

1. When a dog catches a cold, there will be symptoms such as sneezing and runny nose.

2. Invisible dust, dust mites, floating hair, etc. hidden in the air and carpet at home can easily cause allergies and constant sneezing in dogs.

3. Strong perfume, food and other irritating gases or pollen particles can cause irritation to dogs and cause them to sneeze.

4. When dogs are playing, they may accidentally get foreign objects into their nasal cavity, and may also develop a sneezing stress response in an attempt to remove the foreign objects.

5. Bacterial and viral infections can easily cause upper respiratory tract infections, causing symptoms such as sneezing and runny nose.

6. The early symptoms of infectious diseases such as canine distemper and parvovirus are similar to colds, so sneezing, runny nose and other symptoms are also prone to occur.
