I have stopped using aerosols and puffers now use roll on deodorants also iam a chef and found if the fryer oil is old i have chest problems

Stay far away from airfresheners, hairsprays, pool chemicals, baby powder is really bad for lungs

It probably is related to your COPD; it's pretty common to have that sort of reaction to strong scents.

They are definitely an irritant...

It is very likely. I know for me any strong smells : cleaners,air freshener,bleach,cologne/perfume,candles, oils, even vinegar are triggers.
Is your dog long hair or short air? Sometimes their hair /dander (from cats as well) can be a trigger. My dogs don't bother me much. Try brushing him/her daily.
