I made a post yesterday about his behavior towards my brother
http://www.yorkietalk.com/forums/tra...y-brother.html
Basically he dislikes my brother and finds every muscle my brother twitches as a reason to run around barking and growling at him. Tommy will allow my brother to walk him, feed him treats, even let him hold him (while I sit there) but within 10min of putting him down he'll start back up again.
Just now though, he took a change. My brother left that house and knocked back on the door to be let back in. Tommy started barking and running around as usual. When I got up he ran around to me and bit me on the leg.

He kept barking at me and my brother until he left back out.
I know he has it bad for my brother, but I'm kinda shocked and hurt that he'd take it out on me. I've had him for 2 weeks now and we've been getting along great (besides his issues w/ brother) He's a great doggie, I have no interest in taking him back to the rescue shelter. What should I/would you do?
