I am so sorry. Just thinking about it makes me want to cry. Our pets are so loving and trusting, it is truly a huge loss when something like this happens. Wish I could give you a hug in person.
If it's any consolation, my parent's Lhasa Apsa had to be put down a few weeks ago for old age. They had her ever since I was 10. My father Cried for a day or so (I've only seen him cry twice before, once at his mom's [my grandma's] funeral & once at my grandfather's funeral). Just found out today they might lose their collie / golden retriever mix b/c of heart worms... It's a bad day for pets
My thoughts are with you. I lost my beloved Mick about a year and a half ago. It is hard to go through, just remember the love and affection you shared.
With sympathy,
Diane
