You know Marit, I really wasn't thinking of a specific bird/dog aggresion book, maybe there is one, however, I believe any aggression with other animal type reference would work even if it does not have feathers. I don't mean to sound like a know-it-all by any means. I have my own method of correcting the situation and it works. Niki tried to lunge at my daughter-in-laws $3,000 parrot while it was in flight and we both grabbed her together. All I had to do is grab her neck, force her to look at the bird and tell her in a very firm voice that it is not acceptable. I have, though, already cemented that I am the alpha so she understands perfectly and never tried it again. thank dog
