people like you piss me off.
It's okay to hate a dog because the breed has some actually irritating issues (dachshunds barking loudly, chihuahua being yappy, ect) but it's idiotic to hate a dog because 'ewwww it looks yucky!'
Although I agree that pugs are pretty unattractive dogs and because of it are prone to some serious issues, they're generally very nice dogs to down (albeit a bit dumb). They're dogs very well-suited to apartment life, as well as being very affectionate and gregarious, so a lot of people own them. A lot of the pugs I've known would run up to anybody and anything with an excitable demeanor and wiggle around to be pet.
Shut the fuck up. It's like when people say poodles are faggot dogs, when they're the second smartest breed and incredibly good, loyal, affectionate companions.
If you're going to go through all the trouble to hate a breed, go beyond looking at a picture of it.
