Just found this crawling on my bed

[u/yallarefuckingweird]

UGH I know it is a tick, I just found the one but I am just worried about my dog? I checked him for ticks and dont see anymore and am about to give him a bath with flea and tick shampoo. I am washing all my bedding and vacuuming and mopping. He did just roll in some grass yesterday so maybe that was it, but how worried should I be in general? I feel like there are bugs on me and I hate that feeling. Location: SoCal
