Hey Hun, sorry I saw your other post before this one!
I replied saying We also used and use dry food, we have arden grange apparently it's a more healthy brand, things like bakers etc are apparently like McDonald's to them lol!
If go with what is reccomended on the packs tho.
We didn't have any problems with lexi crying etc but if we did leave her I'd leave a radio on for a few months, or get him something he can snuggle into for comfort!
I made the mistake of letting her out while we were out because of the space, she chewed the doors in the kitchen and the main kitchen door as well. Unfortunatly it can take a while to get over the chewing phase! One way to try and stop chewing is to put pepper or chilli powder on places he's not allowed to chew! Sounds horrible but they soon get the idea because they hate it!
Also labs are notorious for always scrounging for food, even if Lexi's just been fed she will still make out she's hungry!
Lexi is really good with Charlie but lexi was with us before we had Charlie so never had to worry about Charlie climbing etc on her, I'd say just keep an eye on little man for a little while as I'm sure when yogi gets bigger the urge to climb him will come about lol!
There's not really much I can give in the way of tips, it's a good idea to look at puppy training, even now if lexi is being naughty she will respond to our commands! Also don't encourage him to eat from the floor or plates etc, our neighbour has a lab the same age as ours and altho lexi will eat anything she's good and won't beg while your eating! The neighbours dog is a nightmare and sits at your feet waiting for food!
Enjoy him! They are lovely dogs!!
