Yes She is spayed. When we are outside playing there could be other dogs in the yard but she goes for this one female dog. I will be throwing a tennis ball for the one dog & the Bully may just be laying around or walking around, she could be 2 feet away from this other dog & I hear the Bully starting to growl next thing I know the two dogs are fighting & the Bully is taking the beating. I always keep a harness on the bully so I can grab her away from the other dog she provoked to fight. Right now they are both laying on the couch together. I just don't know what to do to stop it. Thanks for trying to help me.
