Hunting breeds are not rare. There are many different kinds of hunting breeds because our ancestors needed a little help catching their food sometimes. Although there are many different hunting breeds, not all of them caught the eye of nobility. But the Polish Hound looks like a noble, so the Polish nobles adopted them into their ranks so that they would have the noblest hunting parties in the world. Do not think that this means that the Polish Hound is only good for making your place look more distinguished, these hounds were bred to hunt in the harshest environments, and have fun while doing so.
Polish Hounds were renowned for their endurance in harsh winter conditions. They would never give up once they were on the hunt, and they looked dashing while they were dashing. Nowadays, they get bored easily due to the lack of hostile environments. You need to keep them busy, so let them run after a launchable ball you just made, or gnaw on some pipes to keep their brains active. And once they're done with all that, they deserve a good spa day. There's nothing like relaxing and getting your paws all done up. Your noble dog deserves some royal treatment since they treat you like the King/Queen that you are.
