Everytime I get ready to leave the house, Daisy, my youngest and the one int he picture-who is now 4 yrs old, goes after me & bites/nips. Last week she took a quarter size chunk out of my shin. If she is not going after me, she goes after the other 2. She is a very loving dog, never left for long periods of time, but will not let people leave the house. Anyone can come in---BUT YOU CAN'T LEAVE---
ANY SUGGESTIONS???
