kc can last any where between a few days and a few weeks, generally about 5-7 days, my pup only coughed for around 3 days, generally antibiotics are given to prevent secondary infection, mixed opinions on whether they should be given or not, i gave them to my pup due to his age. generally if the vets said it was kc it probably will be, its very easy to diagnose, and has a sound all to its own! can be worrying the first time you hear it though. we always tell clients a week to 10 days after last cough they are fine to mix, on rare occasions they can harbour it longer, but its unrealistic to keep your dog isolated for months, i went with 10days, my puppy was 13 weeks, and i really wanted to get along with his socialising.
