My heart goes out to you! This past summer we had to put down our 12yr old Malamute\Shepard because he developed a basketball size tumor on his side. It started to affect his eating so we knew it was time. We had 2 days to say our goodbyes. I had to take him myself because my husband couldn't stand to be there. I didn't want him put down without one of us there with him, holding him and petting him. I knew it was for the best but it was still very hard on the heart
