Low blood sugar in dogs is very similar to low blood sugar in humans. Lethargy, confusion /altered mental status, and if very low, seizures and possibly death. This can be caused by poor intake or stress, as you mentioned. Illness can also affect glucose. I have gone by the puppy formula of 1ounce of kibble per lb of dog daily, divided into 3 or 4 meals. (I got this from one of my yorkie books...can't remember which one) For example, a 4 lb puppy gets around 1/2 cup a day, divided between all meals. (1 oz 4 times a day, 2 ounces 2 x day, etc-2 oz =1/4 cup) From personal experience-not a book- I have determined that as they get older and growing slows/stops, that amount will stabilize at approx. 0.6-0.75oz/kibble per lb of dog to maintain without gaining. For example, my dog weighs 8lbs and he gets a light 1/4 cup twice daily plus (too many) snacks.
My little one came home at 7.5 weeks and he has slept in the bed with us from the start. That makes him happy and makes us happy. He has never had a accident in the bed. He will stand on our faces and lick our eyeballs until we wake up and let him out, or if we won't get up for whatever reason, he has stairs to get off the bed and pee on the pad or the furniture or wherever we deserve for not getting up.
As for potty training, be consistant. This is where we failed. With you being teachers and home for the summer, you have a much better situation for consistancy than we did, and hopefully you will have a much better potty trained dog than we do!
