Every purebred I ever had suffered from significant health issues. I think I was just unlucky. The last one, a beautiful black and white Border Collie got pancreatic cancer that quickly spread through her entire system until I could see she was suffering to the point I had to do the humane thing and put her down. She was only 7 and I got her from a Border Collie rescue place when she was 3 so we only had 4 years together.
