They rescued her 12 years ago, and her health has been rapidly declining in the last few months. DH is so sad. I can't imagine how my mil and FIL are feeling. This makes me terrified of the time in the distant, distant, distant future when we might have to make this choice.
I'm very sorry. I was just talking to a coworker about family pets. Our beagle died 6 years ago at the age of 15 and I started crying when I talked about him.
