Thanx for the replies everyone. I checked Puddy's tongue this morning, underneath, too, at least as well as I could considering this is the Pudilator I'm talking about here. LOL All looked and felt normal to me. She doesn't stick her tongue out all the time, just occasionally, and admittedly, it's when she appears to be content, such as when I'm giving her a noggin noogie. I guess it's because her tongue comes out so far and not just the tip sticks out. I'll keep watching her as well as look for other symptoms that were mentioned in Candace's post and, if I see anything slightly abnormal, I'll give my vet a call. She seems ok in every other sense so, in order for my vet to fully examine her tongue, she'd have to be tranquilized and I surely don't want to do that unless it's absolutely necessary, given that she's in CRF and only 5 lbs. I'll keep you updated.
