how dangerous is cigarette smoke to my boston? i've always tried not to smoke around him but i usually like to take him places with me and i smoke alot in the car. i also try to keep most of the windows down if i can. but today i took a joy ride with frenchie to look at the autumn tree's and it was raining so i just cracked my window, and he was fine on the ride (actually looking at the tree's too..) but when we got home and out of the car he threw some sort of hairball fit and i was thinking maybe it was from the smoke. just to be sure i'm not going to smoke around him anymore but i was just wondering if we had any other boston owners who are smokers?
