Hi

Are you feeding them both canned and dry Innova? I don't see the problem with leaving the dry kibble out all the time,unless when it comes to feeding them the canned they don't eat any? When my puppy was 3-4 months old I put the food out for him 3 times a day and after each meal, as he finished/walked away from the food bowl, I would pull the bowl away until the next meal. My puppy now is 7 months and I leave the kibble out all the time. I wouldn't stop doing 3 meals just yet since they are so young, but if you are wanting to do that now, you could make the first meal later and the last meal earlier so they merge a bit and they get used to it, or take half the amount of food out of the lunch feeding? How long have you had them?
