It's a general enquiry about a dog who appeared (rather briefly) in a TV show. Another fan of the show wants to know the breed. As I know nothing about dogs, I thought I'd ask here.
As an aside: The dog was introduced into the show as an adorable puppy in the very first episode and was called Benny. Apparently, it wasn't very long before Benny had to be retired from the show because he was just too enthusiastic when on the set. Pity really, because he seemed such a lovely dog.
Most of Benny's scenes were with the leading characters' daughter. So there was a bright, enthusiastic, 5-year-old actress, and a bright, enthusiastic, few-months-old Border Collie.
I think Benny's denouement came when, for dramatic purposes, both enthusiastic youngsters had to rush to the front door when the doorbell rang. I think that's when the producers realised that there was a problem...
