Beerdogs

This is the pub trying to sell Hot Dogs but I wondered what possible other meanings there were for "Beerdogs"

- A group of canines who perhaps are brought to the pub by their owners and occasionally fed a bowl of beer rather than water
- A name for a group of friends who like to go round drinking beer. "you old beerdog"
- A device that attaches to the bar to keep your beer in place ( as in engineering)
- A category in the CAMRA Champion Beer of Britain for beers that are not so good
- If beer had gender - a group of male beers
- A frankfurter heated and served in a long split roll served with a cold beverage made from fermented malted barley and flavoured with hops

Any other suggestions welcomed....
