maybe it depends on your personal situation. my Addie is dog agressive, but since I don't have anyone around it's not a big issue. she tolerates Ham, but I'd never leave them alone together for a minute. he knows she isn't that loving, so he just leaves her alone. I'm not into dog parks, and it's not a big deal to me that people can't visit with their dog. she is never offleash, either. if a dog comes into the yard, she is in her own fenced yard (because she would get so upset that she fights with Ham. they are now always separated when outside without supervision). if she senses a dog is outside and she in in the house, I know to immediately seclude her until she is calm. because we are rural, I'm just saying it would never be an issue where I'd even consider getting rid of her or putting her down. so it does depend on your own lifestyle.
