Well, when she was a girl, my wife's family had a BCx? from her uncle's farm near Whyalla. Apparently, they were lucky and got a beautiful house dog that lived for 18 yrs. So she has a fondness for BCs. She thought the BCxP would be a nice combination and she loved the look of them.
I think it's back to the drawing board. It's compounded by the fact that we live in a townhouse and our back garden is about the size of your dinner table. In Adelaide, you have to pick up after your dog - and picking up warm dog poo on my morning walk before breakfast isn't on my list of wonderful things to do.
If we get a larger home with a reasonably sized garden, then I shall reconsider the practicalities of dog owning.
Again, thanks for your feedback.
