Dog kennels in Düsseldorf

My wife and I will be traveling back to the US for a week and are looking for a recommendation for a place to board our beagle (5 yr old female) while we're gone in the Düsseldorf area. For a previous weekend trip, we used the services of a sitter that visited our apartment twice a day to walk and feed her, but for a week, we feel like she deserves better care than being cooped up in the apartment all day. We don't have a car, so access by train, bus, or tram would be beneficial.

Any recommendations? We need to find something in the coming two weeks, so any help is *greatly* appreciated.

Thanks!
