Maltese dog

Sweet-tempered, low on prey drive and tiny, under 7 pounds by the American breed standard, which helps a cat feel less outmatched. A Maltese tends to be more curious than confrontational, so first meetings are often a sniff rather than a standoff, and many end up content to curl up with the cat. Its small size cuts both ways. A confident cat can bully a toy dog, so a home with a bold, swatting cat should watch the dog's comfort as closely as the cat's.
