I had a Heinz 57 too! She had wirey hair, and her tail only came out when wagged! She was called Remy...and my nan found school kids with her, they had tied her in a carrier bag and were playing football with her (in about 1988) So she chased them off and brought her home, and she became part of the family...she was an awesome dog, I really miss her!
They also had a border collie called Megan, who shared my exact date of birth! She died when she was 15 (and also me)
My dog was a border collie cross Lab, and he was awesome too...called Charlie (named after Charlie from All dogs Go To Heaven...I cry every time I watch that movie, cos it reminds me of my Charlie) He was my bestie, and I miss him!
