Just out of curiosity, what are some weird antics your dog has?

My dog barks every time we even touch the string that you pull to go up into the attic. he also only eats Alpo if we even try to give him another brand he wont eat it and he likes it microwaved first. plus he doesnt really like treats we buy for him and he is so stuborn he wont learn any tricks, but all this is what makes him have a unique personality
