Strong fit if...
Companion dog first
This breed fits best with people who want a small dog that stays close, cuddles often, and joins normal home life.
Gentle family pace
Cavaliers usually do well in calmer family homes that want daily walks and play without hard-working herding or guardian energy.
You are home a lot
Many bond hard with their people, so the best match is a home where the dog gets regular company instead of long lonely days.
