Hi! I'm new to the forums but have had guinea pigs for 1 year, have had up to 13 in the past, and currently have 11. Lots of mine have had problems (medically) but only minor ones that I understood and have been taken care of. However I am struggling with this one and need help. One of my pigs (she was born in March 2013) has been wheezing. We didn't notice it at first but I now know that was going on then. It's been about 4 months and it hasn't nessisarily gotten worse. We took her to the vet about a month and a half ago and he said she had bronchitis and to wait for it to get better. It hasnt. A few weeks ago my mom was thinking about it and she said she thought it was allergies. I've looked up all of the URI symptoms and all she does is wheeze (she has no other symptoms.). I have changed her to fleece and change it every other day. I try to shake out her hay before giving it to her so that she doesn't get any dust. She lives with 5 other girls and they are unaffected. They stay in a good sized cage. There are no odors from not being changed enough. I don't know what else to do. Please help tell me if that is what you think it is and how I can make her comfortable living like this.
