My name is Abigail!

Abigail was given to us from our friends to help raise our sheep. We got her when she was 8 months along with her sister. We were told she was with 6 other dogs on a ranch and learned her hierarchy but still showed aggression towards her sister. Sister is very submisisve.
Abigail loves to play with her sister and run the prioerrt. She was also great with our sheep for the past year. She herds them and grooms them. However, when she is in a bad mood or it would rain she attacked her sister and our ram on separate occasions. She would also keep them out of the shelter and growl. She has never shown aggression towards ourselves or young children. She wags her tail when name is called but does not come when called. She would thrive in a home without other pets! We joke and say she is a great dog she just doesn't like her role we need her for. We would absolutely keep her but we have 4 other dogs and she would be better in a home she could be the main star of the show.
