['My mom had to put our family dog to sleep last week.', 'Oh, that is so tough. I am sorry. Are you all right?', "It's so hard because we have had her since I was in 1st grade. She was so old and sick."]
That's where you really do have to make the decision for the animal, not us -- that doesn't make it easier when it happens. Do you have other pets?
My mom had to put our family dog to sleep the other day. He was very old and sick. We got her when I was in 1st grade.
