Well, there have been very valid points made here about the detrimental effects to the health of some pure-bred dogs, but to get back to the initial story and the further digging I did about it, the health issues are literally never even mentioned by PETA. Their entire campaign is centered around the slogan/idea that
“all dogs are created equal” - that buying a pure-bred dog means a dog in the pound is going homeless, and that this is somehow equal to the goals of white supremacists. So I stand by my assertion that the PETA people are idiots....
