I am trying to find a book or possibly a series that I read as a child in the mid 80’s. Must have been published 70’s or 80’s.  Definitely a British book, and very detailed illustrations. It’s about a group of dogs that go around a seaside town. The walk upright, wear clothes and talk (possibly some of them even smoke cigarettes?) There are different breeds and I think the leader is a black and white dog. At some point there is an altercation with a rival cat gang.  I can’t remember title or author.
