I have noticed 'dogs welcome' signs on small shops, (not food shops or cafes) in the high street of a small touristy, market town. I like dogs but I don't care for their presence in shops,or the narrow pavements; the shops are small, generally full of goods and people, and dog owners fail to keep their dogs on a short lead. This seems to be following the trend set by mothers taking their enormous buggies into shops and blocking access for other customers.
Our local pub, which serves food, allows dogs in and some owners, (unfortunately one is a friend), allow them to climb on the furniture and wander about unsupervised.
Not a good move.
