Im just going to forget about the dumb mouse! should i have my dog eat it?

It's great that you love animals great and small, but have you ever heard of hantavirus. Mice can be carriers, and guess where the nasty virus is? Their poop!! Get the vermin out of your house now. Use a damp paper towel to clean the poop up. NEVER DRY. You don't want any particles airborne. Use gloves.
