I understand your dileema. My yorkie has this "fits" which can be scary or freaks me out. She does it at differant times and there is not really anything that sets it off. I have read a lot on this and if you have had her checked by a vet and it is not symptoms of a collapsingtrachea-you should not worry. I have not found anything that can be doene to prevent or really stop it. Somer breeds are more prone to others because of their size and the way their sinuses are built. Sometimes I think she sounds like she is honking (a sign of trachea problems) but then she stops. cam home yesterday and she got overly excited and got so loud it really scared me. I blew in her face a little and rubbed her neck but finally I had to just sit and hold her and get her to relax. It does help to gently rub their throat, give them a drink of water and get them to relax. You might get them checked for allegies too. Allergies can make it worse. You dog might be helped by an antihistamine.
