I see your point, it owuld be better all round if pubs were looked at and licenced by size (by the local magistrates) as to wether they could have indoor smoking in one room (say the old snug), or an outdoor are for non-smokers on sunny days (sited upwind of the smokers based on prevailing breeze), a child friendly area etc.

The dog bit is harder, although pubs could have signs up saying "Dogs Welcome/Not Welcome Here" so allergy/phobia sufferers knew that there may be a dog inside.

And I agree a lot of the anti-smoking stuff has gone too far, no smoking in bus shelters that are a roof and one wall!?!
