Quibbling even more enthusiastically than you :-D, I would point out that in pubs where dogs are not allowed, there is no legal requirement (unless there is some odd local bylaw).

Pubs (and cafes for that matter) that do not allow dogs to enter are not obeying a law, they have made their own rule based on a choice about their clientele and market. I think it should be possible to encourage pubs to appeal more to a non-smoking market, without forcing them to ban all smokers entirely.

People will tell you that you can't bring your dog in and it's all down to Elf and Safety, and those people are wrong. There are still plenty of dogfriendly eating and drinking places, Mollydog is pleased to report.
