I have over 30 years experience owning, raising, sitting, photographing dogs. Nine years on Rover. Check out my other client dogs at my instagram: brucedogz. I have shown Bernese Mountain Dogs to champion level. I know that the worst part of a vacation or a job is thinking about how your dog is doing or planning and finding the right situation so you can travel or work without worry. I also have a double sized yard (50 feet wide) which is rare in San Francisco. There are also plenty of dog parks and Glen Canyon for hiking a block away. I usually have 3 or 4 other dogs here and strive to keep a balance of dogs that get along and love playing together. If your dog does not get along with others this won't work for you.
