My now 8 mo Westie, did the same thing at about 4 mo. Everyone
said to wait it out and I had him checked at the vet who said
he's healthy but maybe he's not hungry. I was very concerned by
about the 6th day, so I started feeding him raw (Bones and Raw
Food - BARF, raw meat and bones - RMB). It is somewhat
controversial and not for everyone but he sure took to it. I
think he was just trying to tell me "Don't feed me that crap
(kibble) no matter what the advertising says. I'm a canine,
evolved from wolves. We are not designed to eat grains and
overly processed and cooked protein!"
If you want to try it, research it on the web some (I don't
think you need to buy books) and just start with some cheap
chicken backs chopped into about 1" pieces. He'll eat it.
