Hi,
A Lagotto Romagnolo does sound like a good fit for your situation! They are good with kids, they don't shed, so are considered hypo-allergenic, and are medium-sized. They are considered good for first-time owners because they are eager to please and therefore easy to train.
They do need a lot of exercise, and enjoy being outside to run, dig, and swim. In their younger years, you'll probably need to provide them with a minimum of 1.5 hours of off leash time a day, in addition to lots of interaction and mental stimulation (games, training, etc). If they are properly stimulated both physically and mentally, they are very docile and laid back dogs in the home.
Don't forget the coat is a huge consideration as well. Because they don't shed, they'll need to go to the groomer's at least once every 6 weeks for a cut. And that hair will pick up everything outside, so you'll need to spend time brushing through the coat after every walk.
You can check out our Lagotto Romagnolo breed sheet for more information about this breed.
And if you're just not sure, don't hesitate to take our breed test to see which breed is best suited to your lifestyle!
Hope this helps! Don't hesitate to get in touch if you have any other questions!
