"My" dog is my parents' neighbour's golden lab Sydney. What a sweetie. When she was little, she would get so excited to see me she'd bound through the neighbour's veggie patch to the fence to get some love (and hopefully a walk).
So frequent was that run to see me that neighbour ended up giving up entirely on that strip of the garden and laid down flagstones to the fence. For the dog.
"The schmooze path", as it became known.
Don't have a pic on my computer of her though.
EDIT: to answer the original question, not a particularly big dog. :P
