Perguntamos aos especialistas: seu cão pode realmente evitar arrombamentos em casa? –

Do you really need a security system if you have a dog at home — or is your pup more likely to give burglars a friendly lick? We find many homeowners like the idea of home security, but see no problem with trusting their dog to fend off threats. The experts say dogs can help, but only so much. “Some breeds and sizes of dogs are able to provide better security than others,” says Julie Burgess, a certified dog trainer (CPDT-KA). “For instance, smaller breeds like Chihuahuas, miniature pinschers and miniature schnauzers will most likely be unable to provide serious protection.” Even small dogs may make enough noise to scare away would-be burglars and intruders, though. “Research shows that ‘occupancy cues’ like dogs are major deterrents in attempts to burglarize homes,” says K. Campbell, a certified protection professional. “In fact, the research reveals that dogs of any size are effective. Large dogs pose a physical threat, and small dogs tend to be noisy.”

Let’s take a look at when your dog could effectively deter home break-ins, and when that can cause serious liability issues.

If the only requirement of your dog is that they bark to alert you when a stranger approaches the house, then most dogs will fit the bill, as they will generally make noise when anyone rings the doorbell or wanders around the outside of your house. Burglars do often avoid homes with large dogs, but that’s only one consideration. “I have heard multiple accounts from burglars who say that all things being equal they will always opt for a house without a dog,” says Louis Wood, the owner of a private security firm in San Antonio.

A barking dog, says Wood, regardless of size, may be enough to make the burglar decide to take his business elsewhere — to a home with no potential pitfalls. “A good mindset for a homeowner to be in is how can I make my house as unappealing to rob as possible,” he says. But the data isn’t quite so decisive. In a study published in the journal Society and Animals, researchers at the University of Louisville found that “households with licensed dogs … enjoyed property crime rates 1.71 percentage points lower than households without licensed dogs” — a significant difference, though not a dramatic one. The idea of dogs barking as a deterrent is popular, though, and has even led to Amazon offering recordings of dogs barking on its Echo smart speakers as a security measure. Your family pet may think of you and your family as its “pack,” and may jump in if you are attacked. But that doesn’t mean it will make an effective security animal.

Small breeds like chihuahuas, schnauzers and miniature pinschers aren’t big enough to do damage to a thief, although they can bark to alert you (and for many other reasons). Happy-go-lucky breeds like labs and golden retrievers typically won’t help much, either. Dog breeds more suited to a security job include larger breeds that have a reputation for being aggressive. But there’s a built-in disadvantage to that solution, says Mark Friedlander, director of corporate communications at the Insurance Information Institute. Dogs bred or trained for aggression can be dangerous. That brings us to some large caveats of using a doggo for your home security needs. Dogs can be reliable friends, but less reliable security solutions. Before you start searching for a tactical dog vest for Mr. Scruffles, there are a few difficulties with relying solely on a dog for home security — and why we still recommend smart home security over your furry friends. Let’s break them down.

Guard dogs also come with liability issues, something every homeowner should know about. Brandi Hunter Munden, vice president for PR and communications at the American Kennel Club, suggested breeds best suited for security work. “Some breeds have a natural instinct to protect their family as well as their homes,” she says. “These breeds tend to be loyal to their owners, brave when faced with danger, intelligent and alert.” Munden’s suggestions included the following: Important note: As we mentioned above, contact your home insurance company directly before purchasing a dog with home security in mind, to see if they have any rules about specific breeds. All our canine experts confirmed that it’s not a great idea to use a dog as your only security method. Sure, they can alert you and, if well-trained, protect you. But they can’t call 911, and they can’t be left unattended in a home while you’re on vacation for two weeks. They can also cause serious liability issues even if they follow their training accurately. A robust home security system is more effective in many ways than a dog.
