>>We have an 8 year old male short hair standard dachshund who has always been affectionate and a bit of a licker, but lately he has really started licking compulsively. If he is laying in your lap he will just start licking your arm or leg or whatever, non-stop. Is this a sign that he needs something, or is he just showing affection?

Any change in behavior in an adult dog, especially one in the geriatric years (yes, age 8 qualifies), can indicate a medical change. So, he should see his doctor. But he is showing affection, too. Dogs get very clingy when they are not well, at least many of them do.
