Exploding dogs? "Oh, it happens"

Exploding dogs pose no threat to estate houses
The Northern Territory Government is confident it will not have any problems building a housing estate across the road from a crematorium in Darwin where a dead dog exploded on Wednesday night.
   Police were called to the crematorium because of a strong red glow coming from the chimney.
   Staff told the officers that the dog exploded because it had not been defrosted properly.
   A nearby resident says it does happen occasionally.
   Territory Planning Minister Delia Lawrie says the new houses will not be right next to the pet crematorium.
