I would say no
i think dogs are afraid of spirits/demons or like, the devil, if you do the 'devil sign' with your baby finger and your index finger and your thumb sticking out. (looks like a devil) and point your hand towards a dog, they get scared and back away. well, all the dogs ive done that too have did it..
Im not sure about people, but people have claimed they can se ghosts an other apperations.
In reality, ghosts and after the grave contacting does not exist. "Ghosts" are really demons that dress up like once living things. So your answer would be our dogs will never contact us after they pass away, unless if you consult demons which I hope you won't do.
Dogs, doublets, doubloons, dolphins, diamonds, devils, demons, ducks, dodos, dodecahedrons...
Lesser Demons, Greater Demons and Quest Demons.
