Perfect description right there.They are perpetual puppy. They play and run amok for many years. Most slow down about age 10. They like to snuggle, and throw toys around. They gallop about like wild broncos, hopping and twirling. They love car rides, chasing kitties. They smell good, and are easy to keep.
Their downsides are some health problems. Teeth and gum issues, sometimes sensitive stomachs, and heart problems, and cancers, cushings, to name a few. They tend to be healthy most of their lives except for that last year or two when they start to fall apart. They are big dumb kids, and I love them.
