How to diagnose breathing problems in french bulldogs
Listen to your french bulldog breathe.
Under normal conditions (in cool weather and when your dog is not under stress), you'll probably hear some noisy breathing that doesn't bother him. But, if you close your eyes and hear noisy breathing that sounds like honking or rasping, your french bulldog may have a breathing problem.
Breathing noise is caused by the compressed anatomy of the french bulldog's airways. The noisier the breathing, the worse the condition.
