we have searched for up, down, and around around our neighborhood in search for her. She's the only english Bull Terrier in my town, so I feel as though someone just picked her up, no questions asked, and simply took her. I feel as though I should keep looking for her, but I haven't a clue as to where she would be. We've lost her a couple of times, but she always seemed to be somewhere we could easily find her, but this time, she just hasn't shown up anywhere. I don't know if I should call off the search, or keep looking.
