In Hogans Hero's what did col. klink call his dog?

Me and my friend who is a ww2 fanatic have been having a discussion about hogans heros about what col. klink called his dog....im not being racist but i think it's ****** cuz i think i saw a clip once with col.klink saying it...or some other clip idk...was high, but anyway just wondering haha...i shud be inclined to go with his opinion since he's the one who watched that show but i've looked on the internet and can't find much, thx in advance
