I'm obviously not a vet, but I don't think that they look overweight at all. If they are, you can't tell in pictures. I wonder if there's a weight chart somewhere to figure out what a dogs ideal weight is. I can't imagine these little ones only eating once a day. Missy eats several times throughout the day, only small amounts each time.
Good luck with those future appointments. I'm glad that Pebbles got a clean bill of health
