With the launch of the {\em Wide-field Infrared Survey Explorer} ({\emWISE}), a new era of detecting planetary debris and brown dwarfs around whitedwarfs (WDs) has begun with the {\em WISE} InfraRed Excesses around Degenerates(WIRED) Survey. The WIRED Survey is sensitive to substellar objects and dustydebris around WDs out to distances exceeding 100 pc, well beyond thecompleteness level of local WDs. In this paper, we present a cross-correlationof the preliminary Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) WDCatalog between the {\em WISE}, Two-Micron All Sky Survey (2MASS), UKIRTInfrared Deep Sky Survey (UKIDSS), and SDSS DR7 photometric catalogs. From$\sim18,000$ input targets, there are {\em WISE} detections comprising 344"naked" WDs (detection of the WD photosphere only), 1020 candidate WD+M dwarfbinaries, 42 candidate WD+brown dwarf (BD) systems, 52 candidate WD+dust disksystems, and 69 targets with indeterminate infrared excess. We classified allof the detected targets through spectral energy distribution model fitting ofthe merged optical, near-IR, and {\em WISE} photometry. Some of thesedetections could be the result of contaminating sources within the large($\approx6\arcsec$) {\em WISE} point spread function; we make a preliminaryestimate for the rates of contamination for our WD+BD and WD+disk candidates,and provide notes for each target-of-interest. Each candidate presented hereshould be confirmed with higher angular resolution infrared imaging or infraredspectroscopy. We also present an overview of the observational characteristicsof the detected WDs in the {\em WISE} photometric bands, including the relativefrequencies of candidate WD+M, WD+BD, and WD+disk systems.
