I'll take it 1 step further & ask how many of you would've kept this dog we have?
I'll admit, I'm not familiar with your story, only know from the comments you make but never saw your original threads asking for help. But the answer to your questions above is... Me.
My youngest dog, Holly, is a biter. She'd biten several people by the age of 6 months including 2 so called "professional trainers". She was hung on a prong and bounced off every surface of a car by a SchH trainer at 5 months old when she bit him. And then I was called and asked to foster this dog that no one could touch. I did. She's never bitten me but she sure did test me.
Over a year later, she's good with most people, still dog reactive but it's all fear and she gets along with my two (which took over a month to do while living in the same house) and I choose not to push her with other dogs. We still foster and board dogs regularly and keep her managed.
Our next challenge is she HATES kids and we have a baby on the way but we will work through that too. We're already working with her on it at home. All done without the help of celebrity trainers. I do read and study trainers I align with, study canine cognition and training theory on my own. I don't use force or corrective collars. In fact, putting one on Holly would not go well.
