I own and train hunting dogs for upland and waterfowl hunting. I’ve also done breeding in my younger days. Bloodlines absolutely matter. A puppy from National Champion bloodlines has a far, far better chance of being very good at his job. This goes for ANY working breed that is actually expected to work at their job in real life. And they cost a LOT of money to buy, train, and maintain. But these aren’t foo-foo dogs bred strictly for looks either.

If all you need is a popcorn and movie and sleep on the bed pet, then it doesn’t probably matter very much. Find a nice rescue - they need a home and love too.
