Okay, So new question. When Layla gets tired she tends to act out. Such as.. Chewing on things she's not supposed to chew on, not responding to "no" or other noises i make with the same meaning, or trying to bite. When she acts this way i usually put her right in her crate and she goes to sleep. That seems to be the only way i can get her to settle down. But i'm wondering if i should be doing anything else, or if it's normal. Anyone have any ideas on this?
