Force of habit?

Has anyone heard of excessive licking of surfaces (carpet and sofa in Scamp's case) being tied to GI issues?

I read it recently, so am trialling Scamp on four meals instead of two, as he is definitely worse at licking after he eats, something I hadn't put together before.

Wondering if I should have a vet visit, but didn't want to sound stupid. After all this time it might be a habit.
