My mouse is sneezing and breathing hard. What can I do to help it?

Pet's info: Small Animal | Unknown - Small Animal | Female

My mouse is sneezing and it sounds like it is having a hard time breathing. I don't know what to do. I got her about 3 days ago from my cousins. They say they are 7 months old. I don't know what to do. I have 4 other mice besides the sneezing one, and I don't want them to get sick. The bedding was changed when I got the mice. I also have 2 dogs. I don't know if that is effecting my mouse. Please help me.

I am sorry to hear about your mouse! If you aren't already using a bedding made of recycled paper, such as Carefresh bedding, that is unscented, I would recommend switching to this type. Other beddings can sometimes cause irritation to the nasal passages. If you have any air fresheners or scented candles in the room where your mouse lives, I would remove these as well. If the mouse continues to sneeze, has a green or yellow discharge from the nose or eyes, seems lethargic, or has decreased appetite, or a puffed up appearance to the fur then a visit to a veterinarian is recommended. You can try putting a humidifier in the same room as your mouse or bringing the mouse's cage into a bathroom while you run a steamy shower for 10 minutes to give a steam treatment to help keep the respiratory passages moist.
