I also think that Archie is just using selective hearing. Remy always responds by at least looking, but he doesnt come all the time either unless i have something for him. it must be a Yorkie thing!
ive given up on enforcing "come" to its fullest, he just wont. he understands it but refuses to come unless he gets something out of it.
I, too, suggest retraining him on his name. I wouldnt say to use his names over excessively, just be sure to reinforce something when he does respond. If you call him, say Hi or What are you doing Archie? Try just talking to him like you would a person and see if he gets his name better. Good luck!
