I have been looking for a dog for me and I was wondering if any PRT owners could answer some questions I have about them. What is the difference between a broken and wired coat? Are they kid-friendly if raised with them? Are the bull-headed and stubborn? Are they good in the agility and ratting? How big do they usually get? How much exercise do they need? Those are a few things that I looked up and the internet gave me answers, but I need opinions from the owners of them.
