We have 10 dogs, 8 of them are chihuahuas and they will provoke her and she hurt one last night. She has done it before and she will kill cats too if they get in her territory or run. My family's making me re-home or put her down. Rescue is my preference. I've had her for 6 yrs and I love her. She needs a good home with no small animals and someone who can handle her breed. She climbs chain link fence as well. She went missing for 3 months 4 yrs ago. I got her back but that's when the aggression started.
