This weekend i plan to put my 15 1/2 yr.old Shitzu to sleep....I know it's time, but it is killing my husband, Steve, and me.....Mazie, that's her name, has not been a very happy dog throughout her life - I got her when she was 4 and had been bred 3-4 times already, and treated w/ neglect-given food and shelter, but not much love, and some teasing by stupid people. She has always had an anxiety issue-she shakes and trembles most of the time unless medicated, and has been on XanaX for many years. She rarely wags her tail, hates people, never comes to us, runs off when we attempt to love her up. This is the way it is now (never been so bad, but always had a problem with the above issues. Now, she's blind, hard of hearing, has congestive heart failure so she chokes all the time, and has been incontinent of urine 3 times this week. She goes outside to fenced yard, and stands in one spot with tail tucked between her legs for the longest time. I guess it's time-don't you????? I need some reassurance....
