Our Corgi is in her kennel during the day. My husband and I both work full time. When we get home at night, she runs around the room like she is posessed and plays rough. We try to calm her down but we notice that the older she gets, the more hyper she is. We have to watch her non-stop so she doesn't get into anything, as she bites and chews on almost anything. She is pretty fearless, too, nothing scares her! Anyone else have a crazy hyper dog? Most of the time she is pretty mellow!
