That's what we're trying to do with Bunny. She's definitely dog aggressive, and has a prey drive... for the squirrels and birds. She's also VERY territorial and we've come to decided that she's leash reactive as well.
We do our best to keep her happy and safe. I know its a touchy subject, but we've used some of CM's instructions with her and its really helped. She wears a backpack on walks and is MUCH better about not chasing cars because she's doing a job. She came from Animal Control as a stray, so who knows whats happened in her life before us. We are honest about her issues and control her accordingly. She is definitely able to lead a happy life while being separated from strange dogs (ie no dog parks, Petsmart trips, etc).
Each dog is different, and while there may be some who can be controlled with different methods, there are some who cannot. It also depends on the willingness of the owners too. =)
