Five Massive Canine Guardians Suited to a Life of Isolation

Powerful Breeds That Require Room and Expertise

This could easily have been a list of dogs I'd never want to own. That said, there's nothing inherently wrong with them—provided you're comfortable with a certain level of risk and the possibility of legal trouble down the line. I live a solitary existence, yet even in my remote location, visitors occasionally appear.

A neighbor might send a child over to use the internet; the meter reader shows up monthly to check electricity and water usage; and sometimes I even get a social visit. My dog will bark to alert me, but that's the extent of it. A watchdog suffices for my needs.

None of these breeds are guaranteed to bite, but all possess significant strength, and if a bite does occur, the consequences can be serious. They are absolutely not suited for apartment living. In San Francisco, a pair of Presa Canarios kept in an apartment—where the owners had to take them out via elevator daily—ended up killing a neighbor. Those dogs lacked proper socialization and would have been better off with a hermit at the end of a long, isolated road.

I've observed that Cesar Millan never features these large breeds at his rehabilitation center. Does that suggest none of them require rehab, or that they're too large and difficult for him to handle? Nearly every description of these breeds includes warnings about dominance challenges. Could that be the core issue?

Want to be left alone? Large guard dogs, like this Cane Corso, may make unwanted visitors think twice.

Five Large Guard Dogs for Solitary Individuals

1. Ovcharka (Caucasian Shepherd)
2. Neapolitan Mastiff
3. Cane Corso
4. Presa Canario
5. Fila Brasileiro

Caucasian Shepherd

1. Ovcharka (Caucasian Shepherd)

These heavy-boned mountain dogs have thick coats and a bear-like ruggedness. Size varies, but they are always large—males can weigh 110 pounds or more.

They belong to the category of guard dogs that perform their duties but don't always obey. That might be acceptable in a small Maltese, but in a dog over 100 pounds? The Caucasian Shepherd is known for being both territorial and aggressive toward other dogs.

If you need a tough livestock guardian because wolves and bears still roam your property, and you're not concerned about what else your dog might kill, this breed is a strong candidate. (Also, if interested, see the comment below from dogsrule3.)

Neapolitan Mastiff

2. Neapolitan Mastiff

The dog from Harry Potter is large and has an impressive growl. Traditionally used as guard dogs due to their size (males often reach 150 pounds) and intimidating appearance, some enthusiasts complain that overbreeding has impaired their normal movement.

This is a guard dog, not merely a watchdog. They rank among the best guard dogs for families, and as part of their protective role, they are more inclined to sneak up on an intruder than to bark a warning. They are wary of strangers, so even a well-socialized Neapolitan Mastiff may bite to defend its territory.

If you want a drooling guardian to keep your peace, this is the breed for you.

Cane Corso

3. Cane Corso

This Italian breed is slightly smaller than its cousin the Neapolitan Mastiff, but it is more agile and equally powerful. They were used to watch cattle and hunt wild boar, and surviving dogs have a mouth as wide as it is long.

Like all solitary breeds, this dog requires early socialization, solid training, and an owner willing to spend most of his time with it. The Cane Corso thrives when given a job and kept occupied.

This breed hasn't been outlawed yet, but it hasn't been in the US for long—it was only introduced in 1987. If you want one for protection, act now, as Breed Specific Legislation (BSL) will likely target this dog in the future.

Presa Canario

4. Presa Canario

The Presa Canario is somewhat smaller than some other "solitude" breeds, but it has been described as a pit bull on steroids; it is athletic and moves like a large cat. Males can reach 160 pounds, though most are not that large; they were bred as shepherds and cannot herd effectively if too big.

They need early socialization, good obedience training, and a household where they can be in charge of other dogs. If you can meet all these requirements and need a dog that looks capable of handling anything, a Presa Canario might be right for you.

Fila Brasileiro

5. Fila Brasileiro

This is another breed that discourages door-to-door salesmen. They are large, with a big head and stocky build. One breed characteristic that has been selected for, alongside guarding ability, is the Fila's preference for solitude. They do not do well in households with many visitors. Like all guard breeds, they need proper socialization, but even that is no guarantee. A Fila dislikes change.

In the UK and several other countries, this dog is already subject to Breed Specific Legislation. It is illegal to guard your property with one in those areas. If you don't live there, and you need a dog strong enough to herd cattle and powerful enough to run down a jaguar, this is the breed for you!

My Experience With These Breeds

I expect plenty of negative comments. The only dog on this list I have never worked with is the Caucasian Shepherd, though I have several neighbors who own the others. The Filas on one side of my house are territorial but meek when they escape; the older Fila female on the other side is like any dominant female and always in control, regardless of location.

None of these dogs should be handled by a novice, and if you want a good watchdog for your family, the Rottweiler is much easier to work with and an excellent choice.

But are you ready for some solitude? If you like being alone, just get one of these dogs, and I can assure you that few visitors will come knocking.
