Harry used to be a chewy-paw-nibbler, making his little paws quite pink and sore...
We watched and watched - finally realising that he was using his back paws to scratch inside his ears...turned out he had an ear infection...and then he was licking his paws clean due to that...
We went to the vet - cleared up the ear infection - he stopped licking those yeasty old paws - happy days!
Might be worth a thought? Good luck, Sally + Harry
