Have you tried: Rent.com or apartment.com...not sure about prices posted,but thats who we used to advertise in the past.I know its getting tougher to find apts that allow dogs,unless they are under 40 lbs and now more are putting breed restrictions as in no pit bulls,rotties,dobies,etc...
You could just drive around the area, and see if you find some apartments/condo's and just walk into their offices, or call their offices. Most of the places have some sort of advertisement or sample rooms in the complex. That's how i found my apartment.
