Top 10 Most Over-Bred Dogs

Published by PETA.

One of the many tragic things about breeders (I’m talking about the bad kind here, not the awesome, rockin’ kind) is that their obsession with generating a manufactured, unnatural series of traits in the animals they manipulate inevitably results (as you might expect) in a whole slew of health problems for the victims (not to mention an untimely death for the homeless animals who won’t be adopted as a result). I’m about to drop some science on you here, so bear with me, but this list, of the top 10 over-bred dog breeds in the U.S., is a stark reminder of the sacrifices that these people think it’s acceptable for animals in their care to make so that they can tell their friends that their dog is the fluffiest, or the shiniest, or whatever the hell it is they talk about when they’re not leaving hateful comments on this blog or writing big checks to help the AKC stifle laws designed to protect animals from abuse. Phew! Sorry for the run-on sentence (and the possibly unforgivable use of the phrase “drop some science”)—I tend to get a bit ranty when I talk about breeders. Here’s the list:
