another option is the la belle foundation -

they are great, but i'm biased on this.
we fostered chuggy ^ and his siblings last july and kept chuggy (#fosterfail). one of our best friends adopted his brother so they get to hang out all the time. we were dogsitting the brother (snarls) last week when we evacuated, but timed it perfectly to get to his place in marina del rey right when he got back in town.
they've got a huge following and have already gotten a bunch of help. several celebrities have fostered/adopted from there so they have a big presence on ig. glen powell's dog brisket is from la belle. the problem is that other shelters who get dozens of dogs (and other animals) rely on them pretty heavily and they're a small operation.
we get occasional texts like "are you interested in a new lab puppy for 2-3 weeks?" last week we got an email that said something like "we have 225+ new dogs and cats, send help." we dropped a bunch of beds, toys, pee pads, and other assorted stuff we either purchased or had leftover from the chaos of fostering 3 puppies at once.
long story short, they're local, they do a good job, and they take in animals from about 12-15 different shelters (and that was before the fires). our pups were dumped at some shithole shelter in kern county at 3 days old and somehow made their way to la belle (west la). i can't imagine the shit going on over there, but on their instagram they were like "we have bunnies now!" so who knows.
bottom line, you can go on amazon and order them pet supplies and it will get used asap. sometimes that can be better than sending $, especially if you're worried about a % disappearing, which unfortunately is a real issue.
