I agree with Dwerten- kennel cough can turn into pneumonia- but i'd be surprised if it happend that fast.
did she get the kennel cough vaccine? She could develop kennel cough FROM the vaccine. I would say it is not reverse sneezing as that tends to be a "dry" noise.
Layla had kennel cough- what an awful awful sound- i found that a warm air humidifier helped- if you don't have one- turning on a hot shower and holding her int he bathroom is helpful.
The peeing in her sleep - she is a puppy you said- so it probably isn't related- just an accident.
