I HAVE A 3 YEAR OLD POODLE SINCE HE WAS A PUP ON OCCASION HE SEEMS TO SUFFER FROM TROUBLE BREATHING WITH A COUGH IT USUALLY GOES AWAY IN A FEW SECONDS SOMETIMES ITS WHEN HE GETS EXCITED OTHER TIMES FOR NO REASON HAPPENS MAYBE ONCE EVERY SEVERAL MONTHS OR SO ??????
This could be a collapsing trachea or a "reverse sneeze' Both are common in these breeds. I would have a vet check it out. In my experience neither condition is very serious. vetcare
