Hi Pepperpup and missy322 -
My dog had problems with a stuffy nose similar to those that both of you described. It seemed almost like a really bad cold with lots of mucous. After awhile he started breathing out of his mouth. His stuffy nose though was in conjunction with almost constant sneezing. Are either of your dogs sneezing almost nonstop too?
I'm saying a prayer for each of your dogs! Hopefully it IS just an infection or even some kind of treatable allergy.
Please let me know...
