It's no secret that Pugs are one of the most coveted dog breeds around. But is the Pug-breeding business more sinister than you think? According to this Tumblr thread, absolutely. Purebred pugs, which can cost anywhere from $1,900 to $6,000 have a host of health issues that can be attributed to their breeding. This thread, while hard to read, is a huge eye-opener for anyone with a soul, dog-lovers or otherwise. We hate to say it to the Pug-lovers, but this is more evidence that we should adopt and not shop!
