Fenway is 19 pounds. However, he wouldn't be caught dead in a hat. I tried. I bought the cutest little Halloween hat for him last year and he took it off in 2 seconds flat. Also, PetSmart had the CUTEST beaver head (kind of like Davey Crocket). It was soooooooooooooooooooooooooooooooooooooo cute! I put it on and he took the damn thing off! Go figure! I could never understand how some dogs don't mind wearing hats and Fenway just abhores them!
