On our way to Lake Louise, we passed two pickups and lots of dogs in a roadside turnoff. Tourists can pay $300/person for a 2-hour ride in a dog sled. Each sled is pulled by 10 dogs. The sleds held two adults seated inside plus the driver standing behind. This is the last of four sleds that took off. And at a very good clip too.
There were extra dogs that didn't go on the trip and they stayed behind in the trucks' cages. The sound of 50+ dogs barking was tremendous. But as soon as the dogs started off with the sleds, they grew silent. However, this is the mournful sound of those who stayed behind. Weeping and gnashing of teeth.
