When I had to put my Sug to sleep, I was totally devastated. She was tied to my apron strings. When I got up in the middle of the night, she came to the bathroom with me (she slept at my right shoulder every night) and she did that all her life. When she was gone, the first 2-3 night, Bubba stepped up to accompany me to the bathroom like Sug did. It was so sweet and so tender on his part. But, he only gave me a few nights and then I was on my own. (typical male) He also moved into her sleep position at my right shoulder which he still does. Animals have empathy just like we do.
