We made the appointment this morning. I started bawling as soon as we drove into the car park so DH went in and spoke to them. He didn't make it out without crying.
Booked in tomorrow at 4pm so I am going to be a complete mess all day. Yesterday she was walking around the back yard a lot (we have nearly an acre) and that took a lot out of her. By the time we fed her last night she could barely stand, and she just looks so sad and tired.

I know we have made the right decision, but it doesn't make it any easier.
