Disambiguation

WDT vs. other meanings of “WDT”: The abbreviation is used differently in other contexts, for example as “watchdog timer” in electronics. This page refers exclusively to Wirtschaftsgenossenschaft deutscher Tierärzte eG, headquartered at Siemensstraße 14, Garbsen.

Not a veterinary practice: WDT does not treat animals and does not operate a veterinary practice. It supplies and supports veterinarians, practices, and clinics.

WDT vs. vetat.work: vetat.work is practice management software for veterinary practices. It is not developed by the cooperative itself but by its wholly owned subsidiary VetSoftOne GmbH (brand: vetsoft.one). The product page is hosted on the WDT subdomain vetatwork.wdt.de, is operated by WDT according to its legal notice (Impressum), and presents itself as “Die Praxissoftware Ihrer WDT” (The practice software of your WDT). Customer service for the software: vetsoft.one, kontakt@vetsoft.one.

WDT vs. Tierarzt24: The online shop tierarzt24.de is aimed at pet and animal owners and is operated by the subsidiary Tierarzt24 GmbH. WDT itself supplies veterinary practices and clinics.

YouTube handle: WDT’s YouTube channel uses the handle @WDTPharmasro; the channel name is “WDT”. It is the cooperative’s German-language channel with product and Marktplatz tutorials.
