Are you sure you shot that, its head looks rather flat
Artemis, he will cotton on when hes hungry enough and has NO choice. Just cut out the dry and feed meat, that way it has no choice, its going to eat when its hungry enough I have been having similar problems with my pup, she just wasnt keen on meat. I have now found something she likes and have cut down the ammount of feed, as it seem they need FAR less food when on fresh meat.
Good luck with them, My lot of Kits had there first 'solid' feed yesterday, I gave them abit of minced chicken
