Is pet food actually POISONING our dogs?

It was early spring this year and my other half, Tim, and I were down in one of the lower meadows on our Devon farm, coppicing willow while keeping half an eye on our ten-month-old border collie, Dave, as he indulged in his favourite pastime: moth hunting. Not that we knew it then, but that was the last time in months we would all be worry-free. Half an hour later, as we sat down for tea back at the house, we heard a horrible thumping sound from outside.

The following seconds are still a blur. I don’t remember getting to the kennel, I just recall pulling Dave into the recovery position and putting a blanket under his head. He was convulsing violently,legs wildly paddling, frothing at the mouth. Dave, we would later discover, was having a grand mal seizure and that thumping sound was his head uncontrollably banging on the kennel floor. It was a sound we would come to dread and one we would sadly hear all too often.
