I don't think its sick. I don't think its right to say designer dog lol. Their just cross breeds (mutts) I think its a little ridiculous to purposely try to breed these cross breeds together, though some of them are cute saying their any better than a purebred is silly. I have a yorkie/poodle cross. Though she wasn't bred on purpose it happened and I adopted her, yorkie dad and poodle mom. I've seen tons of those dogs from that post a lot lately though on craigslist and ebay and even breeder selling these designer dogs
all dogs need love no matter purebred or not.
