Thanks!!I did a speed read through most of this but I don't see anything about "budget." I've had people talk to me about Leonbergers for hours and then absolutely trip when I tell them how much they cost initially and thereafter.... On a positive note, I think you're a great potential puppy owner due to the fact that you're doing research and taking it seriously. Can you attend a good sized dog show in your area to interact with different breeds and talk to breeders? I think you'll find the right dog in the Working dog category, look at weight pullers. My Dad actually did alot of hunting in Alaska with Newfoundlands, he was a breeder. Not specifically recommending Newfie to you, just saying weight pullers like Newfies and Leonbergers are all around amazing dogs. Also, I can tell I agree with every single thing said by @TheDawg
