A dog chases a bike, keeps up for a while then drops down dead?
That was not an old dog with a heart that had come to the end of its natural life.
That dog had been OVERFED by its IRRESPONSIBLE and ultimately CRUEL owner.
The owner bears all the blame for this. They probably gave it little "treats" – a bit of chocolate here, a saucer of beer there, a few chips mixed in with the Pedigree Chum. And ultimately, when that poor innocent animal was doing what comes naturally (chasing cyclists, biting them and getting caught in their wheels) it paid the ultimate price.
We should all mourn that animal, for it was a victim, killed by the person it trusted the most.
Two minutes silence. Again.
