I still remember when I first heard that cancer affects one in three dogs. I was at an agility trial fundraiser for canine cancer research and the organizers asked anyone touched by the disease to raise their hand. Almost everyone had their hand up.
It's a scary statistic that hit home recently. Three of my friends have lost dogs to cancer in the last month. The disease has become so commonplace that last week there was an Internet hoax last week about a canine hero who was diagnosed with Hemangiosarcoma .
So I thought it was a good time to review the National Canine Cancer Foundation's 10 early warning signs of canine cancer :
