Yes, most of the breeds are cute....if you are a really an animal lover, you can observe the innocence on their faces..
You can compare it with humans. Like say for an examples, few people appear to be cruel, few wicked, few devilish. Looking at their appearance itself we can guess.
Similarly it goes same for the dogs, while few breeds like the pitbull terrier, rotweiler and some look dangerous, most of the dogs are cute and adorable.
Am a dog lover and the above is my opinion
