This is the email I sent them. This is RIDICULOUS. I think I am losing my patience for people who do these things.
I thought you should know that this poor innocent defenseless pup will very likely end up being used as dog fight bait or worse, he could be sold to a class be dealer where he will be tortured and then sold to a medical or cosmetic research facility where he will be tortured until he dies. Sleep well tonight with the knowledge that you have contributed to the lifelong suffering of a living soul.
Oh, and if you think you can tell the difference between a 'good home' and people who will do horrendous things to this defenseless puppy, you are wrong. They will seem really nice. They might even bring their child with them.
Sleep well tonight.
