Just keep in mind, ALL dogs, in fact, ALL pets are high maintenance. Like people they get sick and depending on how serious it can cost as much as it does to treat a person. They need lots of attention, and ALL dogs bark when strangers come to the door, they hear weird noises, and when fire engines sounding their alarms whiz by.
Some dogs are nervous around kids and busy houses make them agitated and LOUD. Others have anxiety issues and will chew things, get into the trash, or scrape up the carpet even though they are housebroken.
Sounds to me like you're not dog people. Maybe something like exotic fish might be more your speed. No messes, low maintenance, and the only worry is keeping the water the right temp and quality to sustain tropical life.
