Have you done anything to memorialize your pet?
My father keeps small urns of his now-passed dogs' ashes in his VW van, spreading a little bit of them everywhere he travels. He likes to say that he "just wants them to see the view" wherever he goes.
I'm also picking up my Balou bears Urn today I had so far 145 trees donated to have his legacy move on as well as give life <3
That's terrific. Every good dog loves the shade of a tree! I hope that passing on good will to the world helps in your pain during this time.
