I hate when people don't give a reason. I mean, most reasons are rediculous or lies, but at least they put forth the effort.
And at 9 months, she's still very much a puppy. They don't know for sure *what* she's good with yet. When she hits maturity, she may hate all of the things she likes now. And with a deafie, that can be a real challenge. I'd just hate for someone to get a false sense of security with a giant breed with special needs. Hopefully she'll go to someone with experience with a deaf dog. It'd be really awesome if she'd go to someone with experience with a deaf dane.
Sigh.
