Sorry for your loss. It can be so very wrenching to lose a loved pet.
In my opinion, no truly and freely given love is ever lost. In what form that takes concerning pets on the other side, I dont know, but I know that God is merciful.
From what I understand Boxers go straight to heaven because it wouldn’t be heaven without them, Rottweilers go to Purgatory for being so mean, and schnauzers get the hot place for eternity.
