Ok thanks Wat are the odds it will develop to somethin worse
Eh, in the veterinary setting, I'd see maybe 2 pnuemonia cases for every 5 symptomatic kennel cough/URI case. If they're hackin and real snotty, or have green eye discharge, it's a real good idea to get them meds in 'em. It will run it's course from time to time but if they're showing the clinical symptoms that bad then they really should have the meds. 14 days is usually the regimen for oral antibiotics. Some older school vets carry Tylan powder which works well also for when you have multiple dogs.
