8. Chihuahua

There are differing viewpoints regarding the small and cute Chihuahua dog. Some people say that they’re very challenging to handle, while others claim that they’re very affectionate pets. The truth is that they are both.

They are well known for their excessive barking, which demonstrates their possessive personality. Speaking of that, they don’t have any sense of personal space, so if you want a pup like this, get ready to be followed everywhere you go.

They might be small and fragile, but Chihuahuas have a very strong will and are incredibly stubborn. If there’s something they don’t like, these pups won’t follow your instructions. AT ALL.

However, some Chihuahua owners say that they are driven by different factors, so, therefore, if you’re experiencing issues with them, it’s because your strategy is not the best one.
