no clue whatsover. Rex likes all dogs. He is BETTER with big dogs because of how rough he is. in the puppy class (he already graduated, loads of fun!) the only dog he got along with the best was the golden. goo figure
there was a yorkie/maltese in our class but he coward. by week 8 he started to play with Rex and he came outof his shell a LOT more . good luck with what you decide to do. i DO think IMO it is good for them to associate with dogs of all sizes (well not great dane or Irish Wolfhounds) but you get my picture
