Tasty medication to stop excessive licking?

[Jungfraujoch]

Any recommendations please for something that works and I don’t need to disguise with cheese/ham etc!!

Why/what are they licking?

Paws and other areas. Nothing sinister it’s just him! I’ve been giving him some ‘treats’ from Nutripaw (salmon flavour) but he doesn’t like them unless with cheese etc. they’ve definitely helped but I’d prefer something he’ll eat straight off!
