My 4 year old male labrador snorts a lot especially when excited and/or holding a toy in his mouth. A lot of the time he's facing people when he does this. It's pretty disgusting when you get hit in the face with it.
I believe this is just a reaction to irritants (such as dust etc) and perhaps a behaviour he's picked up due to being excited rather than a medical condition
How can I train him not to snort towards people?
