It sounds like all of your choices were made out of love, so I'm sure your dog felt loved and cared for.

Losing old pets is so hard, and you have my sympathy. Our dog had a handful of strokes in her last years, and it's always a tense time waiting to see how things will pan out, how much they will bounce back. You were able to make the choice eventually and spare him/her pain.

Hugs, anon. It sucks and it's gonna hurt for a while, but you'll get through it.
