Well, each district has a DM and DSM (district services manager). Either one could probably help you out. The best way to get the DM or DSM contact info is to simply go into one of the local Petsmarts and introduce yourself to the Store Manager. Kinda shoot the bull with him for a bit and talk about your experience then ask for an email or a phone number so you may forward a resume. Leave one with him and let him know your interested in any openings around the district (including Operations Manager, it pays pretty good, but Petsmart is HUGE about promoting from within) You'll probably move up within 6 months as long as your willing to relocate.
BE PROFESSIONAL! Petsmart is a GREAT first class company and goes for the best!
