Pitchick did bring up some good points. Dumping euthanised pets into landfills opens up a whole different can of worms, as preditors (could be anything from birds to big cats, and bears etc) will scavenge for the bodies, and the result is more dead animals from the euthansia drugs in the dead pets body. I'd rather know the animal was being used scientifically while dead, than sold off alive and experimented on which happens too.
