Maggie is 6 mo and 1 week tomorrow. She weighs just under 2 lbs. I leave kibble out for her all the time and feed her wet food three times a day. She can be a little pig and then other times so finicky !! lol When I got her at 10 weeks she weighed 1.28. She's really been very healthy and active. I do keep nutrical on hand and give it to when she doesn't eat like she should. She wasn't bred to be big either, just the runt. I know it's time to get her spayed and it is just scaring me to death. But I would def give him nutrical and free feed him. Keep the kibble out too.
