So very sad,you can never replace them.
We lost our 16 year old Lab last June and I still have a gaping hole in my chest sometimes when I think of him.
Crackle looks like a great dog who will always be remembered and missed by you.
Oh Dear, It's such a difficult decision to make, but at least for our pets we can do that for them, we can make that decision. Crackle was with you for a long time - a blessing (and a burden right now). you clearly did all the right things for Crackle. Much Love.xx
