We had two dogs, one old that passed from old age and one young that died suddenly to tetanus of all things. Both bonded with my wife, they adored her. They were GSDs who didn’t like too much touch but would lay on her.
We got a couple dogs afterward and neither of them have bonded with her. They like her and love her as part of the pack but it’s not the same. They’ll never go back as they’re “my” dogs now but it hurts to see
