dog-friendly pubs in Llanberis?

Hi, we are planning to walk Snowdon taking the Llanberis path. Im aware that the cafe at the top doesnt allow dogs so will take plenty of supplies with us. We would love to return to a cosy dog-friendly pub on our decent to rest and refuel. Bearing in mind that we may all be wet and a little dirty, somewhere not too formal or busy so the pooch can sprawl out please !

Many thanks :-)
