7 Most Loyal Small Dog Breeds
1. Chihuahua
Chihuahuas are not for the faint of heart. These tiny warriors (5–8 inches, 2–6 lbs) have unwavering loyalty and will fiercely protect their favorite person like a miniature pinscher on steroids. Their protective instincts can make them wary of strangers, but their strong bonds with their humans are unmatched.
Don’t let their size fool you—these little dogs have big attitudes. Their spirited nature means they demand attention, and if ignored, they’ll make their presence known. They’re lap dogs, but only when they feel like it—otherwise, expect them to run the household.
Exercise-wise, a Chihuahua needs daily walks and mental stimulation. They’re easily trained, but only if you establish yourself as the boss. Otherwise, they’ll rule your life with their stubborn, feisty charm.
Purina claims that their short or fluffy coat is easy to maintain, but their small size makes them cold-sensitive—think sweaters, heated beds, and plenty of snuggles. Bottom line? A Chihuahua isn’t just a dog—it’s an attitude.

2. Yorkshire Terrier
Yorkies are mini powerhouses wrapped in silky fur. Standing 7–8 inches and weighing 4–7 lbs, they’re tiny but tenacious, embodying the phrase “big personality in a small package.” Originally bred for hunting rats, their fearless nature makes them highly protective of their humans.
They may look fancy, but Yorkies are all attitude. Their loyalty runs deep, and they don’t hesitate to stand up to bigger dogs if they sense a threat. They love being the center of attention, and if they’re ignored, they’ll make it known—loudly.
These highly trainable dogs need daily exercise and mental challenges to keep them from getting bossy. If not properly trained, they’ll take over your life like a mini dictator with short legs and a fluffy crown.
Their silky coat requires regular grooming, but it’s worth it for their show-dog-level elegance. If you want a dog that’s bold, devoted, and a little dramatic, the Yorkie is for you.

3. Shih Tzu
If loyalty had a luxury edition, it would be the Shih Tzu. These 9–16 lb, 9–10.5 inch furballs were originally bred for Chinese royalty, and trust me, they haven’t forgotten it. They don’t follow you—they expect you to follow them.
Despite their royal lineage, Shih Tzus are incredibly affectionate dogs and love endless attention. If you’re looking for a lap dog, this is the ultimate snuggle machine. However, their gentle nature doesn’t mean they’re pushovers—they’ll give you the side-eye if they’re not pampered enough.
PDSA reveals that their exercise needs are minimal, but they still enjoy short daily walks. More importantly, they need human interaction—ignore them, and they’ll make you pay with soulful stares of disappointment.
That fluffy coat? High maintenance. Regular grooming is a must unless you want them to look like a mop with an attitude. But if you want a devoted, regal companion that thrives on love, the Shih Tzu is lap dog royalty.

4. Cavalier King Charles Spaniel
Cavaliers are the ultimate Velcro dogs. These 12–18 lb, 12–13 inch charmers live for one thing: being as close to you as possible. Forget personal space—this dog is going wherever you go.
They’re great family dogs, incredibly affectionate, and fantastic with young children and other dogs. They’re playful but not overly hyper, making them ideal for various living environments—apartments, houses, even palaces (which they’d prefer).
Daily walks? Yes. Intense workouts? No. They’re gentle-natured, easily trained, and just want to be loved. But leave them alone too long, and you’ll break their heart.
Grooming is moderate—expect regular brushing to keep their fluffy coat looking fabulous. If you want unwavering loyalty wrapped in a wagging tail, Cavaliers are excellent companions with endless affection.

Maltese dogs look like floating clouds of fur, but don’t be fooled—they’ve got big dog energy in a small package. At 7–9 inches and under 7 lbs, they have a deep loyalty to their humans and zero patience for being ignored.
They’re great companions, thriving in human families where they get plenty of attention. These dogs don’t like being left alone—they want to be your shadow, your best friend, and possibly your boss.
Despite their cute appearance, they’re fearless. They’ll alert you to anything unusual and expect you to take them seriously—no laughing at their tiny but tough attitude.
Britannica notes that their fluffy coat needs serious grooming, but their devotion makes it worth it. If you want a dog that’s fiercely loyal, incredibly affectionate, and a little demanding, the Maltese is lap dog perfection.

Havanese don’t just walk—they strut. They need daily walks and a bit of playtime, but they aren’t hyper. Their highly trainable nature makes them great at tricks, therapy work, and stealing your heart.
That fluffy coat needs regular grooming, but their big personality makes up for it. If you want a dog that loves you unconditionally, makes you laugh, and always looks stylish, the Havanese is a top-tier choice.
