I hope some SoCal members can come up with some ideas to help you keep your dog. Is it possible to bring your dog to work with you, have him crated at your desk or job site or even in your vehicle if temperatures permit? If you just keep him with you during days, commutes, and at night when you're at home there may be less barking. It would mean some lifestyle changes for a few weeks until you found a place to live but may be the cheapest option, and worth it. We can't allow owner surrenders on PBF but maybe we can help you keep your boy, hopefully for the next 10-15 years.
If it makes you feel any better: I rent and own a pit bull. There are tons of threads on here to help you, but basically I look on Craigslist and send e-mails to landlords, tell them I also have a dog that is a certified Therapy Dog with his CGC and we do take obedience classes and do some competitive/rally obedience. I mention he is crate trained, house broken, neutered, and on flea prevention. I go and meet the landlord. I see the place and present a professional appearance and win them over, and THEN we talk specifics about the dog. If he has to meet the landlord then I exercise him and have some treats, so he can do simple tricks like shaking paws or rolling over or getting into a crate on command, etc. It's not easy but I just found a place to live in my price range within the last few weeks.
Most of those big big apartment complexes do have weight limits and breed limits. I stick with smaller ones, individually owned, etc.
Did you adopt Blue from a shelter/rescue? They will usually take a dog back, or maybe they can help you find a way to keep him. If he's from a breeder, I'd definitely touch base with the breeder; see if they can do some boarding or maybe one of their clients is looking for their bloodlines for a pet and they may be able to match them up?
