I've got two white campbell babbies who will be 4 months old in under a week and one of them (Pumpkin) is breathing fast almost all the time. I've been comparing her to the other girl we have (Daisy) and she'll be breathing fast even when Daisy isn't. We've been back and forth to the vets but nothing has worked yet. Is there anything I can do to help her breathe a little easier? I've got asthma myself and know how hard it can be to feel out of breath so much.
