That's where "nanny dogs" come in. The term "nanny dog breeds" is often used to describe dogs that are especially gentle, patient, and reliable around kids.

A "nanny dog" isn't a formal breed category, but rather a nickname used to describe dogs known for being affectionate, steady, and good with kids. Even if some have a strong or muscular build, it's their temperament-not their appearance-that defines them. With proper training and socialization, they can become dependable, well-balanced companions and some of the best dogs for families with kids.

7 Best Nanny Dog Breeds for Families with Children

While it's hard to say that any one breed is the best nanny dogs, there are certain canines with a reputation for being some of the friendliest and most patient pups, points out Elisha Stynchula, CPDT-KA, certified dog trainer.

Newfoundland

When you think of a family dog for children, a Newfie may come to mind. "Newfoundlands are gentle giants," Stynchula points out.

The Newfoundland is one of the largest dog breeds, but they don't use that big size to wreck havoc. This breed is loving, kind and loyal. They are also known for their love of children, making them a great fit for any families with little ones. But while this breed is big, their energy levels aren't incredibly high. As a result, your Newfoundland will love to play and nap, pretty much equally.

Breed Stats

• Personality: Devoted, sweet, patient
• Height: 26-28 inches
• Weight: 100-150 pounds
• Lifespan: 9-10 years

Saint Bernard

You may recognize this gentle giant from Disney'sPeter Pan, where Nana-the Darling family's devoted nursemaid dog-is often portrayed as a Saint Bernard. While fictional, the character reflects the breed's long-standing reputation for being watchful, patient, and deeply loyal to children.

So, if you're looking for a large breed often recommended for families, the Saint Bernard is an amazing choise. Stynchula explains, "Like the Newfoundland, the Saint Bernard is calm and affectionate with a sweet, easygoing nature. For many families, these personality traits are important."

It's this combination of that makes the Saint Bernard such a trusted nanny dog for families. It's no surprise experts say they're one of the best dogs for kids.

Breed Stats

• Personality: Playful, charming, inquisitive
• Height: 26-30 inches
• Weight: 120-180 pounds
• Lifespan: 8-10 years

Cavalier King Charles Spaniel

If you prefer a smaller dog, Stynchula suggests the Cavalier King Charles Spaniel! "This pooch was originally bred for royalty as a companion and lapdog, which translates well to many families with kids," she says. "They are a solid family dog with a reputation for simply being nice. Plus, they love being around people and are eager to please."

Known for their affectionate and gentle nature, Cavalier King Charles Spaniels tend to thrive in close-knit family environments. Their mellow temperament and strong desire for companionship make them especially well-suited for homes with children, where they can easily adapt to both playtime and quiet moments. Who wouldn't love one of these pups?

• Height: 12–13 inches

Bernese Mountain Dog

The Bernese Mountain Dog is chill and affectionate, which is a surprising contrast to the breed's oversized build. "For many families, calm might be very important for their child and lifestyle," Stynchula says.

Ashley Reely, a professional dog trainer at Meraki Dogs, also praises this breed. "Bernese Mountain Dogs are big, goofy and loyal," she says. Reely also notes that this breed is friendly toward nearly everyone, which is a personality trait that can come in handy if you have caregivers in and out of your house. Also worth noting: The Bernese Mountain Dog is strong, just in case you need help hauling or lifting things around your home.

Breed Stats

• Height: 23-27.5 inches
• Weight: 70-115 pounds
• Lifespan: 7-10 years

Staffordshire Bull Terrier

Believe it or not, even though the Staffordshire Bull Terrier cuts an intimidating figure thanks to its muscular build, this pup is all heart. "The Staffordshire Bull Terrier is a good option as well," Stynchula reveals, adding this this pup is "sturdy and sweet."

Just keep in mind that this breed has a little more energy than others on our list, so be prepared to give your pup plenty of space to run. Still, "they have a reputation of being known as ‘nanny dog,'" Stynchula says. This breed craves time with its humans and loves to be physically close, creating a cuddle buddy for the entire family.

Breed Stats

• Personality: Clever, brave, tenacious
• Height: 14-16 inches
• Weight: 24-38 pounds
• Lifespan: 12-15 years

Shih Tzu

Besides being pretty, the Shih Tzu is also an amazing dog for kids of all ages thanks to the fact that they were bred to be a companion and lapdog. "Cuddly and affectionate, they are happy to lie with you until it's time for a walk," Stynchula explains.

The Shih Tzu is also typically quiet, which can be a helpful trait in family homes where a calmer environment is preferred. They are generally eager to please and can be relatively easy to train with consistency and patience. In addition, they do not require a high level of exercise or intense mental stimulation, but you do want to keep grooming n mind. "These pups have moderate grooming needs, but their coat can easily be kept in a shorter style," Stynchula says, helping to manage upkeep while maintaining their signature look.

Breed Stats

• Personality: Playful, affectionate, outgoing
• Height: 9-10.5 inches
• Weight: 9-16 pounds
• Lifespan: 10-18 years

Beagle

The Beagle has a hunting dog past, but this breed is now known for its kind personality. "Beagles are sweet dogs we all remember from childhood movies and books," Stynchula says.

Beagles are usually friendly and gentle with nearly everyone. They also have a generally upbeat nature, which is a perk for all households. Just one thing to keep in mind, per Stynchula: "If your child is sound-sensitive, a beagle is not the best match." Though, for all other families, this sweet-natured, kid-loving pooch is worth a look.

Breed Stats

• Personality: Curious, friendly, merry
• Height: 13-15 inches
• Weight: 20-30 pounds
• Lifespan: 10–15 years
