URBAN WILDLIFE -- For years, Cranbrook, British Columbia, has had a problem with an urban deer population that's burgeoned to nearly 200 animals.

But it wasn't until a video of a deer attacking a dog went viral that the town was galvanized into action.  The town is adopting the Helena, Mont., model of trapping deer, euthanizing them and distributing the meat to the needy. Cranbrook already has an ordinance that prohibits feeding deer.

The deer are pleasing to see, but they can be dangerous to pets and people and destructive to landscaping when they take up residence in a town and lose all fear of humans.

The video above might be disturbing to some people.  You can't blame the doe mule deer for defending her fawn. But it's simply best not to let deer to move into town.
