sneezing dog

Question
my 13 year old Australian Shepard seems to be sneezing a lot the past few days. It only seems to be when she is upright.  Not so much when she is laying down.  She sniffs a lot like something is tickling her.  There is no discharge or anything like that.  We did have her boarded a week or so ago.

Answer
Was she vaccinated for Kennel cough? was it intra-nasally or by injection? She might be coming down with kennel cough but as it is called, they usually cough first.

If it continues for another day or two it's time to have the vet look her over. She might have inhaled some hair from the runs outside if they were not real clean.
