7 Best Small Dog Breeds Choices for a Loyal Watchdog

7 Best Small Dog Breed Choices for a Loyal Watchdog

Most people probably think of larger dogs like German Shepherds when it comes to guard dog breeds. However, you don’t need a big dog to keep a watchful eye on the house.

The smallest dogs can be very devoted to their role as house security units. They might not necessarily be able to physically block the intruder, but they can definitely alert you to their presence when unfamiliar sounds are coming from outside, or if there’s unusual activity taking place.

Small-sized watchdog breeds are additionally more conveniently accommodated than larger breeds that are intended to protect. Many of them can be easily housed in an apartment or a smaller house, if they are given enough movement, training, and stimulation.

Obviously, a good watchdog isn’t an aggressive watchdog. A well-socialised dog should be able to tell the difference between an unknown person and a real threat.

These are some of the breeds you want to be familiar with if you’re interested in finding small guard dogs that are good companions while also being natural watchdogs.

Best Small Dog Breeds Choices for a Loyal Watchdog

1. Miniature Schnauzer

Miniature Schnauzer

Named an easygoing breed by Orvis, the Miniature Schnauzer is a charming dog, but under this pretty look is a watchdog that is very serious about its job.

When this breed was created to be an all-round farm dog and ratter, watchdog capabilities were bred into its temperament.

One of the best things about the Miniature Schnauzer is that it doesn’t need to be gigantic to show its authority. This fearless breed may be an affectionate dog for its own family, but it is always wary of strangers.

Miniature Schnauzer Profile

Miniature Schnauzers are also smart and trainable, which can be great when you want to teach them when to bark and when to go to sleep.

This breed enjoys being a part of the family. When provided with regular walks, playtime, training, and lots of interaction, you’ll have a friend who is content to keep an eye on the backyard one minute and to sit down with you the next minute.

2. Toy Fox Terrier

Toy Fox Terrier

The Toy Fox Terrier has an interesting blend of two personalities. One side has an affectionate nature, and the other side is definitely a Terrier by heart.

Toy Fox Terriers were originally bred in the U.S. to be barnyard ratters, but later became popular as companion dogs. They had a lot of courage, alertness, and confidence because of their Terrier blood.

This breed will not simply ignore something unusual taking place. It is alert and intelligent, and will be quick to alert its owner due to its watchdog nature.

Toy Fox Terrier Profile

They’re also fun. It’s not unusual for Toy Fox Terriers to turn their attention to an unusual sound and, in the next minute, turn their attention to their toy.

Their small size makes them a little vulnerable, particularly with larger dogs and animals. These little dogs have big personalities and will be perfect additions to families that want great watchdogs.

3. Miniature Pinscher

Miniature Pinscher

Called the “King of Toys” by the AKC, this tiny dog isn’t particularly interested in acting like one despite what its physical size might be.

Mini Pinschers are often described as confident and courageous. They make for excellent watchdogs as they alert their owners instantly if they see something out of the ordinary.

They can also be quite energetic. These dogs aren’t satisfied with being carried from one room to another, and are very happy to be active and given opportunities to use their minds regularly.

Miniature Pinscher Profile

This is a very confident little dog and, hence, proper training is important. The Miniature Pinscher should understand that its family values include being alerted to unfamiliar activity.

Their keenness will be one of their best traits when proper limits and boundaries are set.

4. Chihuahua

Chihuahua

Called charming by Purina, the Chihuahua is a fearless breed that is not afraid to bark at bigger animals.

These small pooches may be very sensitive to their environment, and they can get very attached to their owners. Chihuahuas are small, but when they’re in the mood to pay attention, they’ll do so. These dogs are alert and have a watchful nature.

Perhaps one of the most important attributes of a Chihuahua as a watchdog is its awareness. From external noises to people coming near the door, or someone entering the door’s proximity, it can quickly become alert.

Chihuahua Profile

This same temperament must be considered when it comes to socialization. A dog that is constantly on alert will not make a good watchdog. A confident companion must be able to recognize the threat and evaluate proper responses instead of reacting to every unfamiliar sound.

Chihuahuas are generally convenient to travel with, and do well in small homes. When provided with proper exercise and grooming, they can easily adapt to any environment and stay satisfied as well.

5. Lhasa Apso

Lhasa Apso

The Lhasa Apso adds a unique element to the small watchdog discussion. This ancient breed is not just made to be gorgeous and sit next to its owner. It has a long history in Tibet, where it was kept as a sentinel dog inside the house, which explains why the breed is naturally alert.

This character gives this breed an unusual personality. It may be affectionate with familiar individuals, but is reserved with strangers. This breed is independent and intelligent, but it isn’t necessarily interested in doing something simply because you’ve asked it to.

Lhasa Apso Profile

Patience, consistency, positive training, and reinforcement can do a lot of good.

The Lhasa Apso also has a long coat which gives it a unique look, but it does require regular grooming to be maintained. As long as you’re comfortable with the maintenance, this furry friend will keep watch of its territory and warn you of any potential threats.

6. Yorkshire Terrier

Yorkshire Terrier

The Yorkshire Terrier may be known for its fancy coat and small stature, but there’s a lot more Terrier under that furry skin.

Originally bred to be working dogs, Yorkies are confident and alert. They can be very vocal when something distracts them, and they also rank high on lists for dogs with protective qualities, which is another trait Yorkies are known for.

They can be devoted to their families and become very aware of what is going on around them. The visitor at the door might get a far louder reception from this small dog than what they imagined.

Yorkshire Terrier Profile

Yorkies are also clever and versatile, making them a good fit for various homes. They do not need to be housed in a large environment, but do need activity and mental stimulation on a daily basis.

Then of course, there’s the coat. More grooming is required for a Yorkshire in a long show coat than if it is shorter.

7. Pomeranian

Pomeranian

The Pomeranian seems merry, furry, and cute, but it should not be underestimated.

Pomeranians are very aware, intelligent, and have a good reputation as watchdogs. They are active, trainable, and good family dogs for adults with children who know that these little dogs are not toys.

One of their most useful attributes is their size. They enjoy a lot of exercise indoors and are adaptable to short walks, so they are an ideal choice for someone living in the city.

Pomeranian Profile

Due to their small stature, they are sensitive dogs and can get hurt from rough handling. Children need to learn to play with them and not treat them like toys.

Pomeranians can also be very talkative, making it easier to hear when they detect something strange. That alertness should be honed so they aren’t barking at anything that moves. They’re the kind of dogs to be drawn to whatever is interesting, so they’re pretty fun to have around.

Conclusion

You don’t need to look for a large dog to get a faithful companion to watch over your home. Many small breeds are confident, aware, and have a strong prey drive which will help them to protect you from any danger.

The important thing to remember is that a watchdog and a guard dog aren’t the same thing. These breeds are good for home security, but they do not have the physical capacity or the urge to be a physical threat to intruders.

However, if you are looking for a pet that can be a family member and also watch out for you and your family, then do come back to our guide to select the right pup for your home.
