Sam is home. They took three of the four lumps/tumors they had identified, and even though it means he will need to go back in the future, I'm glad they made that decision, Sam is hurting badly. They took one from under his left front leg, one from his left side near his flank/abdomen and one from his left shoulder.
We've pulled a mattress onto the living room floor, and I'll be spending tonight with him. We think he needs the extra comfort.
