The Geeky Gecko presents: aggressive small dog breeds you don’t want to mess with!

Dogs are cute, wonderful, playful, and fluffy, and they can make our lives better. However, even if they love their owners a lot, there are times when a dog can attack their human parents.

Most people imagine large breeds like Pit Bulls, German Shepherds, Rottweilers, etc. when they think about dog bite injuries. Due to their large size and power, when these strong dogs feel threatened, they might attack people and cause severe injuries or even fatalities.

However, don’t be surprised if you see these aggressive small dog breeds get angry and try to bite you. They can threaten people on the streets who seem suspicious, attack strangers when they approach their owners or visit them at home, or even try to bite their owners in case they don’t like something.

While cases of pups attacking their humans are rare, it doesn’t mean that they don’t or didn’t happen. If you want to know which are the most aggressive small dog breeds you don’t want to mess with, keep reading!

  1. I do not agree with you that the Pekingese is a hunting dog. Where did you get your information. They were bred to not be able to run or to venture far from their owners
    They are not a mix of other dogs. They have been a separate breed for many hundreds of years . Have had them for over 40 years and have never had any trouble with them being aggressive to people or other pets. You should definitely do more research on the breed.

  2. My dog, a Bichon Frese doddle acts very aggressive. She barks at anyone or any dog that is on “her street” incessantly. Because of this my husband gets up at 3 to 4 am to walk the dogs (I have 2 of the same breed) so as not to encounter any other dogs.

  3. Dachshunds can be a pretty aggressive breed, I’ve noticed over the past 68 years! (I sustained a mean bite from one, and was only visiting the owner in her living room and discussing recipes.)
    They were bred for hunting badgers, so they are pretty bad-ass.

  4. Many dogs (of any size) can be aggressive if poorly bred or mistreated. I have had experience with most of the dogs on this list and the only ones I agree with are the Chihuahua, the bull terrier and possibly the cocker spaniel (but individually, not as a breed). Just my opinion but . . .

  5. As the owner of a chihuahua, I agree. They are very quick and without proper socialization, they can be dangerous. My baby has been handled by many friends and family. He is sweet and loving. However the only dog bites I have had is from ilmannsred chihuahuas. It is all in the raising. If they are socialized from puppy age, they are sweet and loving, unless they have been breeed by owners that breed family members ,which can cause mental issues.
