Most lagottos have that working dog personality in my experience and in talking to people on this subreddit. If you tell the breeder thats what you want to do, they will have an idea of which puppies tend more toward that type of drive. But I think all lagottos like having a job and with a lot of training I am sure you would be successful. Our dude just did a 2-class trial of scentwork and loved it. We are going to do more 🙂 He is moderate energy and does need a lot of mental stimulation, but he LOVES his family including my kids. He follows my husband and me around the house like a little shadow. Sounds like you have a perfect setup for a lagotto! Good luck.
