Sparkie is our 40 mile an hour couch potato. She loves to play with other dogs and run round the park at high speed and then likes to come home and sleep. She is a gentle soul with a lovely temperament. She doesn't tend to bark unless she is trying to pursued another dog or you to play with her. She is still only a puppy but is getting there with recall etc. - she is 7 months but it would let me put that on the system.
