I have a property management company, Anchor Property Management, but don't have anything available now or coming up.
If Wavro works out remember where you heard it when it's time to buy.
Wavro link below good luck and if you decide to use him I'd like a review from you.
Our sister company is a property management company that may be able to find you a place that will accept large dogs. Go to http://www.glrealtor.com/rentals/ or call them directly at 510 522 3322.
There are several detached homes etc with yards that agree to rent to dog-owners. I know....I am renting out my duplex to people with dogs.
Otherwise, check the SF SPCA's Open Door website site for other pet friendly options. I'd also create a pet resume if you haven't already. Due to insurance restrictions, some breeds are restricted.
Unfortunately, there is a shortage of pet-friendly rentals in S.F. You can always try to negotiate with a property owner by offering a larger deposit & hiring a dog walker when you're away at work &/or look into doggie day care when you're at work of which there are numerous choices in SF. A tired dog is a happy/good dog.
Let me know if you might be interested in my flat.
