I don't know the physiology, but of all the dogs I have had, and that is many, they all have done this.
It depends on how many times you sneeze(:
A human will sneeze millions of times during their lifetime. There is no way to count exactly how many actual sneezes will occur.
Twice
Impossible to answer ! On most occasions, we sneeze because something has irritated the lining of the nose - therefore, a person might not sneeze once in a day. On the other hand - someone with flu may sneeze a hundred times in a single day.
There's really no answer for that. Dogs sneeze due to, allergies, dust, or respiratory issues. Like me for example, I sneeze A LOT and you never really know how many sneezes are going to come out of your nose (Same for the dogs). :O
How much your nose is tickled.
Sneezing in dogs can be caused by allergies or dust/pollen, etc., but many times it also is basically a way of "laughing": when a dog gets excited or when you rub a dog's tummy vigorously, the dog might sneeze the way humans might laugh.
If pollen counts are extremely HIGH, I can sneeze over 200 x a day
none
From what I understand dogs are not supposed to drink milk. Its the same with many other animals!
I sneeze 75 times a day. The average human sneezes 4-5 times a day. (I work in a pepper factory during the week) and I have terrible pollen allergies (I work in a flower garden on weekends) I am allergic to cats and dogs and foster both. (I probably foster 20 families a month) My fostered cat always curls up on my shoulder and rubs her body on my face when I'm trying to sleep (Those days I sneeze probably close to a hundred) My fostered dog sits on my lap and lays his head on my face and starts licking my nose when I'm trying to watch TV (Those days I probably sneeze 85) I sneeze more with cats than dogs because cats have more fur. And you won't believe this, but my animals SHED. Shed all around my house. But they mostly like to shed on my bed. Everything in my house is covered in cat and dog fur. And worse my friends think It's FUNNY! They always try to make me sneeze even more.
