I know how to solve this problem. I know just what your Hubbie needs to do. But I need his email address. I can tell him how to end this discussion.
BTW, (back to Lab pimping) I've raised a number of dogs (mostly Labs, but also a couple of English Setters - Nutso dogs. Loveable as all get out, heart stealers to the max, but crazy as loons - and border collies - my second recommendation, so intelligent, you would come to think of them as smarter than your kids. And maybe your husband. Heck, they can probably do algebra), and I have yet to lose a minute of sleep due to a Lab puppy's interference. I’m sure some people have, but you don’t have to let that happen. All puppies are goofy, selfish, and untrained, but there are ways to deal with all that (and that goofiness will win your cold, cold heart) until you can get it acclimated and trained in the basics. One month? Two months?
Such good companion dogs for all ages. Suburban areas are OK, but rural areas are best (you don't have to walk them, just let them out), but I've seen people in urban areas walking them around. With scoops.
They are short hair dogs (I think your Grandpa’s dog had to have been some sort of mix), a Labrador retriever is a short hair dog - I've never heard of a long hair Lab unless it was a collie (or something)/lab mix - so they aren't as prone to activate allergies as long hair dogs (and cats) are.
I do sympathize with your allergy/pet problem though, in the household in which I grew up mom had Siamese cats (yeah, the real yowlers - they were nightmares, emphasis on 'night') and my childhood (until I discovered Benadryl) had a basically unending nose dripping wheezy sneezy theme.
