New owners took after last May, the month after this massacre:

Outdoor Adventures Whistler, which assumed full operational control of Howling Dog Tours in May 2010, says that it has made "significant" changes to the business to ensure the humane treatment of its animals.

Those changes include giving away 75 dogs, neutering males and creating an open-pen kennel rather than tethering the dogs. Guns are no longer allowed on site and the company's new policy is that euthanasia must be performed at a veterinary office.

But it could be too late for the tour company.

As news of the gruesome cull spread across Canada and into the U.S., animal lovers took to the internet to ask for a boycott of Outdoor Adventures Whistler. In just one day, a Facebook page called "Boycotting Outdoor Adventures in BC, Whistler" gathered more than 10,000 fans.

I hope the previous owner is dealt with FULLY - BCSPCA, every authority is all over this.
