Hi Collapsed Trachea is the one thing that came to mind, but since you said she was checked already the only other thing that I can think of is allergies. I have four Yorkies and one Yorkie mix (Maltese/Yorkie) and the only one that does this is my Newman who is 10 and has a collapsed trachea. I wouldn't just accept it. I would watch and maybe even video tape it and bring it to the vet. Maybe then he can get a better idea. Elaine |
