he's just divine but a couple of things are worrying us.
he hates walking in the lead and will stop dead in the middle of the road so frequently it makes walking him anywhere nigh on impossible. we look cruel dragging him down the road whilst enticing him with treats but he just won't budge. once off the lead he'll be as good as gold. just detests the lead which is a real prob.
second is food. he's fed three decent sized meals a day yet seems perma hungry. I know labs are like this by nature but he seems to always eat grass (which the dog trainer/ behaviourist said he'd be hungry) and will just chase every scrap of food. inc licking the pavement after the bin men have been.

what is actually normal for this age/breed?
