>>I used a flea spray from the pet store on my lab, while the fleas appear to be gone his skin is really dry and flaky especially near his hind legs. I am thinking it might be an allergic reaction to the spray - has anyone else experienced this and what can I do to stop his scratching?

Dry skin is abnormal for Labs, since they have special oil to repel water from coat and skin. Scratching can do severe damage, and this problem can go deeper than skin, too. I'd get him to a vet, pronto.
