My dog has one odd quality. Often I'm playing with him. Always if I want to give him a stroking or I blow on him, just for fun, he always gonna sneeze. It really seems he can arouse it. BlueWolf thinks he can do that because there are different dusts (dust+y= the name of my dog! ) in the living-room where he react to.
I think that's nog right, but I don't know what's the solution.

Do you know why he can do that? Do you have a dog who does something like what my dog does?
Or perhaps you have a theory about it? I'm curious...

My Lucky would sneeze whenever I blew a dandelion in his face, though I dont do that to him any more...I dunno, I suppose dogs get allergies too, mabye?

You should ask your vet, mabye he/she can shed some light on the situation?

Yes, I think maybe you're right.
I can also go to the vet... but first I want to hear some more opinions of the other people on the forum.
