The Poison of Crufts

So it appears a dog at Crufts has died of some mystery ailment which his owners are describing as a poisoning. 

The reporting right now is as follows:
~The dog died in Belgium 26 hrs after Crufts
~Cubes of beef were found in the dog's stomach
~ We are being told up to three poisons are involved that were enough to "kill a horse."
~ We are being told that this is by some AR nutjob.
~ We are being told two or three other dogs may have also been poisoned but no one is coming forward yet.

I seem to be in a  minority that is raising my hand and questioning the validity of this story.

It seems unlikely to me that a dog would die of a poisoning 26 hrs after a show. It seems odder yet to me that the dog's other stomach contents could be identified. It also seems odd to me that they said they could identify three poisons that were enough to "kill a horse" without the dog dropping prior to that point.

To me it seems far more likely the dog got into something on the way home or upon arriving home. Either way if a dog is dead this is a sad event - but we need to wait for more information and not leap to hysterical conclusions or point fingers.
