I've been having the same problem with my two. They lick themselves so much (mostly paws) that it wakes me up at night here lately. I've checked for skin irritations and fleas and bathed them both in an oatmeal bath for dogs. I'm not sure what it could be, but I don't see that it is likely they both have allergies. Now it has progressed into itching...the vet says dry skin, but it I don't really buy it. It seems like it happens more when we're getting ready for or are already in bed.
