What is the favourite pet you have had? Cat? Dog? Iguana? Tarantula????

I love the dog that I have now but apart from him the favourite has to be the family dog we had when I was a kid. My dad trained him do do amazing things, he played hide & seek and could pick the colour of smarties that he was told to pick, yet they say dogs see in black and white.
he was a miniature version of the Dulux dog, called Scratch.
