Oh ChelseaBaby, I am so very sorry for what you are going through. I too had to make that choice for our 14 yr old mix breed last November and it was VERY difficult. I read these types of posts and offer my condolences in knowing that we will all have to face that point in our babies' lives some day. I have 3 yorkies & another coming home on Monday, and the thought of losing them is unbearable.
Hugs
to you at this difficult time.....and RIP
Rocky.
