The food thing is a Pomeranian trait. Mine goes to the kitchen at noon and 5:00 waiting for someone to come and eat. If we go out to diner, he gets pissed and will start eating his food about 7:00 when he realizes we aren’t eating at home. It was my wife who taught him to beg and I still have a hard tie forgiving her for that.
Ours has tummy issues so for us when Nemo begs for food we are always thrilled, means he feels good :-) Ours also suffers with the collapsed trachea which I guess is common in Poms(or so I have heard) when he gets super excited he makes the goose sound which is not fun to hear but he gets so super excited sometimes he breathes like a maniac so I just pet him til he calms down
