Maybe its a Brighton 'n Hove thing.Firmly in the DOGS OUT camp. It never ceases to astonish me, the scale of entitlement dog owners exhibit, about where they can take their animals.
I wouldn't even have them in a pub that serves food, personally. Welcome to sit outside on the terrace or in the beer-garden - like the smokers.
I can't remember ever seeing a dog in a restaurant here in North Kent in 35 years.
(I am not including pubs that do food in my equation. They are not restaurants.)
