A sister for ALVIN

HELLO my name is ALVIN, I'm LOOKING for a little sister, I was a gift to a lady whom suffers off depression, she Fell in love With me and I'm the centre off her life. But one THING makes her sad and even me...! When she has to go to work, I have to stay By myself. She went to THE kennels to see if she COULD get me a little sister, but unfortunatly They Are all Very Very big dogs, I AM tiny! 1.9 KG. Mummy has a little flat, no garden, so she cant have big dogs...and I AM to small. So PLEASE HELP HER BUY A LITTLE SISTER TO PLAY WITH ME.
