Milo has always had this thing for flying bugs. When he is outside he loves to chase them and catch them in his mouth. The problem w/ this is he doesn't know that some bugs "bit" back. He has gotten stung on a few occasions. We like to tease him when he is in the house and ask him where the bug is. He always searchs for it flying above his head and gets frustrated when he can't find it..thus the whining. He is a funny dog!
