What stupid rules
Obviously invented by a very ignorent person!
I would be more concerned about having a dog in that type of enviroment for the dogs safety rather than the publics.....how many overweight pub dogs have u met....I have met a few!
Also if its a pub that serves food their will be health and safety issues re where the dog has access to.
Also be careful when rehoming an adult as some can come with problems thanks to the previous owner...be prepared to spend lots of time working through them and basic obedience is a must for a dog likely to be amongst lots of familier people and strangers on a daily basis.
