One of my Chihuahuas got this weez/cough about a week or 2 ago and it sounds like when they pull too hard on their collar/leash when you walk em,,, you know that sound when they choke themselves,,, she is doing it several times a day,,, as it doesn't seem life threatening in anyway, I thought I'd check here before taking her to my vet whose new car, boat, and new vacation home were all financed by me and my patronage, LOL.
