This jolts my memory of situations by friends, who adopted dogs from the HSUS and were lied to about temperment, health....

I personally find the local SPCA's much better.

Oh please see your own vet soon. If the poor dear is bleeding, crying, snappy and plain miserable, get another opinion (in writing), take it to the HSUS so you have a leg to stand on. I'm sure their egos will never admit to wrongdoing so you want to cover all your bases. You can't accuse them of anything in the media without backup.

I say take it to the media when you have proper documentation. I'll tell you what. My biggest mistake (due to being zoned out) was NOT taking my dog attack to the media. Not to harm the dogs, but to teach their owners a lesson in responsibility. If I don't adequately win my lawsuit, you may read about me because it's all public record.
Not to mention I never got an apology and I'm madder than he$$.
