I've got an ~8 month old dobe who I adopted at about 6 weeks old. She's been to a puppy training course, and responds really well to all the basic obedience commands (sit, down, stay, come, etc...). She and I go on 2-4 mile runs every day, and have several refresher training times lasting about 15 minutes each day. When she and I aren't working together, she is either in her crate (when I'm gone) or out in the house with toys under my supervision.
My problem is this: she snaps! When we go outside for some old-fashioned run and tug toy playing, she immediately begins to get aggressive. Her hair stands up, she starts to run circles around me, and she snaps and growls at me. This behavior just started about a week ago, and I'm at a loss. I've tried being firm and saying "no," which just irritates her more. When I turn to walk away/ignore her, she just waits for me to come back and begins the behavior again, no matter how much time I give her to "cool off" (anywhere from 5 to 15 minutes). I'm not sure what I need to do to stop this behavior. She's never been aggressive like this before, and we didn't tolerate her biting us while she was teething. Any suggestions?
