I posted a few weeks ago when I found an aggressive mast cell tumor on my chocolate lab Lena's back leg. I had the tumor removed, and by the time we went to have her stitches removed, three more tumors had erupted, including a baseball-sized one in her abdomen. Last week I made the appointment and got pain killers to keep her comfortable until this morning. She was happy and frisky all week, not having any idea how sick she was. She passed away peacefully this morning at 11:20 as I rubbed her sweet ears and kissed her muzzle. Heaven got a great dog today. I miss her already.
