I found this guy in my backyard. I have no clue what he is, though I'm assuming a jumping spider, after doing a little bit of searching. For context, I live in Southern California, close to being right in between LA and San Diego. It's suburban, though there are a few reserves that are close by. It is incredibly small, probably no bigger than a dime. It's mostly orange and black with some rings of white on the legs. It's pretty hairy as well. The only thing I'd like to know is if it's poisonous or dangerous, as I don't need my dogs getting sick or injured. If possible, I would also like some links for some background reading on it!
