hello,im looking for some advice regarding our 12 week old bichon frise puppy.we have had her for 2 1/2 weeks and everything has been great however the past 3 or 4 evenings whilst dozing on the sofa she has awoken and started to retch which lasts a couple of seconds.my first thought was the onset of kennel cough but it only ever happens during the evening when she is asleep on the couch and besides going for her first vaccination she hasnt been outside the house and my other dogs are all upto date with there boosters and kc vacc.apart from this she is great active and eating/drinking fine.i have been reading up and apparently a collapsed trachea is quite common in the breed im now in a panic that our perfect little pup has some sort if life threatening condition.can anyone shed any light?
