Starving stray bit the hand that fed her!
When I asked about adopting Nina, the shelter told me she was unadoptable due to food aggression, since she had (twice!) bitten the fake hand they use to test for that when it took her food away! Realizing that if I was starving I would also bite the hand taking my food, I persuaded them to let me adopt her. Since I knew some professional dog trainers, and I did not have any other pets or kids in the home, they let me have her for half the usual fee! Ironically, for the first month she wouldn't eat unless I sat on the floor right next to her!
