Sneezing

[kiesha09]

My dog has started sneezing alot - particularly in the morning when he wakes up. He probably does 10 - 15 sneezes at a time. THen in the afternoon he is sneezing more than usual but definately not that much. It started yesterday morning when we first woke up. I don't think it would be something lodged up his nose since he hadn't been outside (like grass seed or something) as he would have begun sneezing the night before I would think.

He is perfectly fine otherwise. He's still eating, drinking, playing, no discharge from his nose.

Any ideas what it could be?
