Well his records show that he got a bordatella shot at his last appointment about 7 months ago and isn't due for another one until next year. Guess I should have checked that first, but does that rule out kennel cough? A google search is showing me there was an outbreak of canine influenza in the Dallas area back in May, and Odin has been to several areas in the metroplex since then (Mostly between Irving and Rockwall since we take him to my parents house with us every Sunday, but I did take him to the dog park at white rock lake about a month ago) and it's possible he's been exposed?
He's been having what we thought were minor allergies since the weather changed. Just a little bit of lethargy, minor goopy eyes (like when a person has sleep in their eyes, no kind of film or anything), and some scratching/licking on and off, but no nasal discharge and the coughing is brand new just in the last week. A vet tech friend of mine suggested giving him a baby benadryl for it, but it didn't seem to help any so I only gave him the one pill and quit.
