My dog won't eat his food. Whats wrong?

he may be stressed or ill if youve changed your routine or his he could find it a real stress.. take him to the vet .or try petending to eat some of his food from his bowl before giving him his bowl this will tempt him and also if he doesnt eat it within 10 minutes take it away.. its not cruel just reinforces your status as his pack leader see Jan Fennels amichan bonding techniques www.janfennel.co.uk
