For the past 8 years I have been dog sitting for three of my neighbors when they go on vacation, sometimes at the same time. One owns a great dane, one owns a shitzu, and one owns a shepherd and a lab. So I would say I have significant experience with several breeds. Not only do I make sure the dogs use the bathroom, but I make sure they also have fun and run to get exercise when I take them on walks. I am really into animals especially dogs, so your dogs happiness is important to me when I am taking care of him or her. I am available mostly during the weekend but I can try to work around my work schedule for you
