been a while back but we had a rescue Scottie, my best buddy. Everything was great, he starts having these bowl movements, went to the vet. Rectal cancer....tried everything we could including some holistic stuff....took her in, put her down, cried for what seemed like a moth (or more). This was a little over 2 years ago. She was with us for 8 years...should have had another 8....Not even considering a replacement, because there ain't one (for me anyway)....
I've seen a holes have dogs running loose, tied to trees and their dogs live a full life......a bad one but non the less....
