I had a lovely reading with a client recently where his dog came through and thanked him for his assistance in helping him pass on. The dog even mentioned the date of his passing.
Another time, a dog came through to thank my client for rescuing him and encouraged her to rescue another dog when she was ready.
So do all dogs go to heaven? Yes. And cats and fish and horses too. All of us are created in our creator's image and share in that light source.
