She's 18, and over the last 6 months, she's been steadily going downhill. Went to the vet this morning to see if there is anything that can be done now to increase her quality of life, but there isn't (apart from high-dose painkillers, which would only be a temporary solution really).
So I now need to make 'that' appointment... I know it's the right thing to do, it's heartbreaking to see her - losing weight, almost completely blind, arthritic, losing weight and with a substantial mass around her liver (the vet felt today), so her quality of life really isn't what it should be.
But I've had her since she was 5 weeks old, she was my first 'baby', and she's been part of my life for so long now.
And how do I explain this to my kids?! DS is 8, DD is 3, and they both totally love her. This is so hard.
