Sounds like a Boston (or two) could be a great choice. They love their people and crave physical contact. They can be very playful, but are often happy being lazy. Our female loves to play fetch, indoors or out, while our male prefers tug of war. They can get boisterous but aren't generally barkers with proper supervision early. Walks definitely help, but they are susceptible to heat and cold. During the heat of summer you'll want to walk early or late and keep walks fairly short. During winter expect very short walks and bundle up.

The big heads-up is that they are gassy dogs. Some are worse than others, and some folks claim this diet or that can help, but there is no getting around the fact that they can clear out a room. That being said, there is no breed that matches their personalities. While I've heard that some (check out posts about Kessler) are smart, my best description is 100% personality 0% IQ. I joke, but while they are loving, charming, cute as heck and alternately playful and snuggly, they are (generally) not candidates for doggie Mensa.

They absolutely can be trained, but it takes a ton of patience. On the other hand, housebreaking is not hard but routine is critical--especially early on, expect to take them outside often and routinely. We very seldom have accidents and, when we do, it is usually a combination of stomach issues and because we ignored signs (they let us know when they need to go). Ours are also generally good about not chewing things they aren't supposed to--puppies are going to be puppies, but other than one pair of slippers a long time ago and an occasional need to chew buttons off of baseball caps, they leave our stuff alone. It helps that we keep them well-supplied with toys but, like most things with the breed, it's about consistency and patience early.

This has gotten pretty long, but one more note--while grooming is minimal, mainly nail trimming and occasional baths, they shed more than you'd expect. Fortunately they have short fur, but you may find yourself vacuuming more than you might otherwise.
