hmmm (treading carefully) The Farmer was within his right unfortunately and he could have tried to see if they were friendly and looked at their tags "first" and called animal control" - probably didn't notice they were wearing tags from afar and only noticed the minor commotion with his animals, should he have "noticed" that they were friendly critters and not as yet done any harm to his stock
Incorrect.

The dogs were in his livestock's feeding area, putting the animals in a "panic state," said Insp. Bruce Townley of Durham Region police.
Inducing panic in the cattle indicates to me that the dogs were either chasing the cattle or scaring the cattle by their mere presence. That's harm enough. Having 1,000Kg critters running around in a panic is never a good thing.
The farmer was under no obligation to wait for any further harm to occur before putting an end to the threat to his herd.
