Recent weeks have seen gruesome and tragic incidents in both Toronto and Edmonton involving  dogs attacking children, leaving one child dead and another with life-changing injuries. Those stories are backed by numbers from many Canadian cities—including Toronto and Edmonton—showing a surge in attacks or dangerous incidents over the past couple of years.

What's behind the spike in attacks? Is it pandemic puppies, as some suggest? Lax enforcement? Incompetent owners? All of those and more? And more importantly, what are we doing about it? What works and what doesn't when it comes to keeping dogs under control in our cities?

GUEST: Dr. Tim Arthur, Ottawa veterinarian and Canadian Veterinary Medical Association President-elect
