8. Brussels Griffon

The Brussels Griffon wins hearts instantly with its expressive face. These rare dogs nearly vanished during the world wars but survived through dedicated breeding efforts. Highly social, they dislike prolonged isolation. Originally bred for rat hunting in Belgian stables, they're now cherished companions. Their coats come in rough or smooth varieties and four colors: red, black, black and tan, and beige. Their human-like expressions and distinctive beards make them unmistakable. Despite small stature, they're confident and full of personality. They form intense bonds with owners and may develop separation anxiety if left alone too frequently.
