11 Best Companion Dogs Who'll Always Be by Your Side

Are you looking for a dog who can be considered your new best friend or your shadow? You’re looking for a companion dog or a dog who is friendly, affectionate, and so devoted that they might come off as clingy. Companion dogs are usually lapdogs, but that doesn’t mean they have to be small — big dogs can be companion dogs, too. These breeds (and their mixes) are also usually medium- to low-energy and good with young children, seniors, or other pets.

We’ve compiled a list of the best companion dog breeds out there. These dogs vary in size, fur maintenance, mental stimulation requirements, and exercise needs. And many of these breeds and their mixes can be found at shelters and rescues near you. These 10 breeds have something important in common, though: They all love unconditionally and are incredibly loyal companions to their pet parents.

Why are dogs such good companions?

Dogs make great companions because they can literally smell when you’re stressed or sad (we swear!), while providing emotional support and unconditional love. They can also make you more social because they may lead you to socialize with other pet parents at the local dog park. And you’ll become more active because, depending on their breed mix, your pup can go on adventures with you, like hiking, long walks, and even runs. And of course, dogs are great companions because you’re never alone when they’re by your side. Here is our comprehensive list of the best dog breeds (and their mixes) that make excellent companions.

Top companion dog breeds and mixes

1. Shih Tzu

The Shih Tzu, nicknamed the “Lion Dog,” makes a perfect small companion dog. Coming in at up to 16 pounds and 10.5 inches at shoulder height, the Shih Tzu has been a lapdog for centuries and is happy to continue that tradition. Highly affectionate and great around other pets and young children, Shih Tzus aim to please and enjoy charming their humans with tricks and snuggling.

Because they’re bred as lapdogs, Shih Tzus only need short walks and a little indoor playtime to keep them happy. Their elaborate mane is a little more high-maintenance, though: They require daily brushing and monthly baths to keep looking and feeling nice.

2. Papillon

The Papillon, which means “butterfly” in French, tops out at 10 pounds and only reaches 11 inches at shoulder height. This small breed is known for their unique wing-like ears and loving, devoted nature. Papillons are good with young children, but kids should be taught how to interact gently with this small pup (or the dog could get injured). This regal pup is surprisingly smart and active despite their small stature, and they will want to play fetch inside more than you might anticipate. The Papillon’s silky-soft fur only needs to be groomed every month or so, but occasionally running a brush through it will help it stay tangle-free.

3. Golden Retriever

It’s probably not surprising to see the Golden Retriever on this list, because they are one of the most famous companion dogs. Golden Retrievers are highly intelligent, obedient, cheerful, and eager to please. They enjoy having some sort of job or task for mental stimulation — like working as service dogs — and sometimes make it their life’s mission to support their pet parents in whatever way they need. They’re also good around young children and other pets.

This pup is a bit larger than the other companion dogs on this list so far — they can weigh as much as 75 pounds and reach 24 inches tall at shoulder height — and require a lot of exercise, including long walks or play. Deprive them of this, and they might grow destructive. Their beautiful, golden double-coat of fur also sheds heavily twice a year (and moderately the rest of the year), so they should be brushed frequently.

4. Maltese

The Maltese is one of the most famous lapdogs in the canine world. This petite, white pup only weighs up to seven pounds and reaches 9 inches in height, so they also make the perfect purse dog — but aren’t recommended for families with young children or other (larger) pets. This breed can be doting, but they can have a sassy streak, which is undoubtedly from years of sitting on the laps of rulers.

Like the other toy dogs on this list, the Maltese doesn’t need a ton of exercise, though they have a high enough energy level to play multiple times a day. That silky white coat won’t keep itself clean — the Maltese requires a light, daily brushing to prevent tangles, as well as frequent baths with shampoo and conditioner to keep their coat healthy.

5. American Staffordshire Terrier

The American Staffordshire Terrier, nicknamed “AmStaffs,” are big cuddle bugs — and their size will not stop them from trying to be lapdogs. This breed can reach up to 70 pounds and 19 inches at shoulder height, but they’re still a bit clingy, which is ideal if a pet parent is looking for a companion dog (they even make great service dogs). This breed wants to be around their humans all the time and can grow destructive if they’re left alone for too long. AmStaffs are a little more high-energy than the other dogs on this list, so older people would be better matched with senior dogs. Their short, glossy coats are easy to care for, only requiring a weekly once-over with a brush.

6. Maltipoo

The Maltipoo is a mix of a Poodle and a Maltese, and is generally as charming as their Maltese parent and as smart as their poodle parent. Good with kids and other pets, Maltipoos are friendly, affectionate, and usually pretty vocal. These pups can weigh up to 20 pounds, reach 14 inches in height, and typically have curly white fur — which should be brushed daily and bathed monthly to stay healthy. This breed is considered mostly hypoallergenic because of their low-shedding coat. Maltipoos do get the zoomies and require daily walks and playtime.

7. Cavalier King Charles Spaniel

The name of the Cavalier King Charles Spaniel is a mouthful, but this breed, also known as a “Cavalier,” has a devoted following. If you look into a Cavalier’s big, puppy dog eyes, you can see why kings and queens liked to keep this regal dog around. Highly affectionate to the point of clinginess, the Cavalier is very loyal and would spend absolutely every minute with their humans if they could.

These small companion dogs are a very vocal breed, so pet parents should be prepared for arguments with them over dinner and at treat time. Cavaliers are happy to chill on couches and take long naps, though they enjoy indoor and outdoor playtime as well as long walks. Cavalier King Charles Spaniels have longer fur, but it only needs to be brushed weekly to avoid matting.

8. Chiweenie

The Chiweenie, also called the “Choxie,” is a mix between a Chihuahua and a Dachshund. This cute pup, who weighs around 12 pounds and reaches 10 inches at shoulder height, is great for city dwellers who don’t have a lot of space. Due to their stature, they are ideal for families with older children, cats, or similarly sized dogs. Chiweenies are surprisingly energetic pups for their size and require more than 30 minutes of exercise per day.

Chiweenies are loyal and typically develop a strong bond with one person, though they can still be affectionate with other family members. This breed can be considered “yappy” because they bark frequently, especially at unexpected noises, which makes them good guard dogs. Because Chiweenies don’t have breed standards, they can have either long or short hair (depending on their mom and dad) and vary in coat color.

Weight: 5 to 20 pounds

9. Boxer

The Boxer is a muscular, athletic pup with a heart of gold. This large breed might look like a bruiser at around 80 pounds and 25 inches at shoulder height, but they’re happy-go-lucky, goofy dogs who love spending time with their companions. Due to their patient nature, they make good pets for families with children. Because they are so devoted, though, they can grow overprotective if not socialized and trained from a young age.

Boxers are high-energy and thrive best in a fenced yard to play and run around in. Because of their required exercise level, they don’t make the best companions for seniors. They have glossy, short coats that need to be run over by a hound glove or gentle brush once a week.

Weight: 55 to 70 pounds

10. Miniature Schnauzer

The smallest member of the Schnauzer family also makes a great family companion. With their sweet old-man-like faces and beards, the Miniature Schnauzer is a friendly, devoted breed. They can reach up to 20 pounds and 14 inches at shoulder height, so young children should still be supervised with a dog this size. Still, Mini Schnauzers used to be farm dogs and are stronger than they look. This pup has a medium activity level and will need more than one walk a day to stay happy and healthy. Their curly fur coat is double-layered (the top is wiry and the undercoat is soft) and needs constant brushing, though they shed a little.

11. Mixed breed dog

You don’t need to go to a breeder to find a great companion. Mutts make great lifelong friends. Some pet parents say that their shelter dog saved them as much as they saved their dog. Just ask rescue staff about the dog’s temperament, exercise levels, and whether they’re good for families with young children, the elderly, or other pets — to see if that dog is the right fit for you. Even if you are attached to the idea of a specific breed, many purebreds end up in shelters, and there are purebred rescues out there to help you find the dog you want.
