Anyone who knows greyhounds, galgos, or indeed most any dog, knows this natural behavior as "sleep startle" or, as the less dog savvy person might call it, "sleep aggression." It is not fair to call it aggression, however, since a dog who reacts this way is not being aggressive; she is simply responding to being startled from a deep sleep. This might even be where the saying "Let sleeping dogs lie" comes from. (Many people would do the very same thing, though they would yell, hit, or kick rather than nip.) But just in case this isn't obvious to everyone, we put it in our adoption contracts – DO NOT DISTURB YOUR DOG WHILE S/HE IS SLEEPING OR EATING – as I'm sure other rescues do, too.
Children are often biters. What do you do when a child bites someone? Just wondering.
We also have no-euthanasia clauses in our adoption contracts, and liquidated damages clauses for breaches of contract, as at least some other rescues do. But whether the adopter in this case suffers any legal consequences is really secondary here. And while the person who killed Jade will, I hope, not be given another galga, that doesn't help Jade, does it? Nor does it unbreak the hearts of those who rescued her.
