28 So-Called ‘Dangerous’ Dogs Behind ‘Beware Of The Dog’ Signs

Dogs are more than just adorable furry companions. In fact, they can be aggressive house guards too. So, it’s not surprising to see a lot of homes with a “Beware of the Dog” sign on their front gates. After all, it’s often an effective way to deter burglars from breaking into people’s homes. Plus, it conveys a fair warning to any ill-intentioned person out there of the impending danger ahead.

However, there are times when dogs themselves seem to have not gotten the memo at all. Instead of projecting themselves as ferocious creatures, they end up doing otherwise. Indeed, nothing beats the purpose of this menacing message more than a friendly, welcoming dog posing next to it. And apparently, this kind of irony has invited more dog-loving strangers to people’s homes. Luckily, they’re all kind enough to share the cuteness with us!


“Beware of Dog! (Because she is soooo vicious!)”


“Not entirely sure what I need to beware of exactly?”


“He was a feisty one! Undid my shoelaces a few times”


“This gorgeous girl lives in my neighbor’s front yard with a huge ‘beware of dog’ sign. The only thing I have to beware of is spending hours petting her!”


“Now see, that’s the puppy. Who you gotta watch out for is his daddy.”


“No.. Open the gate..”


“Of course I will be aware of the dog. I love dogs. I am aware of all dogs.”


“I think I’ll take my chances”


It turns out that the use of dogs as a form of protection dates back to ancient civilizations


“Beware of the dog”


“Oh well, at least you tried.”


“So if I see a sign in the future, expect the opposite?”


“aware of dog, pls pet dog”


“You shall not pass… until I get a treat.”

Similarly, dogs often served as house guards back then. Meanwhile, there were some that served as livestock guardian dogs, protecting livestock against potential predators. From then on, people started developing specific breeds as guard dogs. German Shepherd was among the first breeds of guard dogs, with its origin dating back to 1899. And up to this day, they still hold this title as they take on police work and military duties.

“Seriously. She’s super scary.”


“Dear Mailperson, I think there’s a mean dog somewhere in this yard because the sign says BEWARE but I haven’t seen them yet. So feel free to leave the pet treats Dad ordered with me.”


So, are dogs effective for home security?


“Very risky…”


False Advertising



“No squirrel is safe.”


Well, in a way, they’re an effective deterrent. Research suggests that 65% of convicted criminals find dogs, especially of large breeds and with loud barking skills, intimidating. However, the presence of CCTV cameras still proves to be the most effective deterrent. Even so, having a well-trained dog lurking behind your fences can certainly provide your home with an extra layer of security.
