Koala and Deni left Montana a few weeks ago, and recently a friend asked me whether Cali misses Koala. He then jumped to the next level and asked whether dogs understand that someone has left temporarily versus having “crossed the rainbow bridge.”
Those are pretty big existential questions for dogs to consider, but I think they are up to the challenge.
First, does Cali miss Koala? I think that she misses Deni more and that there are lots of aspects of being an only dog that Cali thoroughly enjoys. Cali has regular play dates with her pal Maisy — and the two of them play better together than the pack of three did. Cali always gets to choose where we walk, as well as where we stop so she can sniff. She gets all of the dog eggs at breakfast and can have her snuffle mat whenever she wants (within reason).
But yes, I think she does miss Koala. Life is quieter and more boring when Koala is not here, and Cali rarely has a playmate. Not that Koala is always the nicest playmate, but the girls do often have a lot of fun together. When Koala is not pulling on Cali’s tail, that is, or scheming to steal her treat ball.
I also think that Cali understands that Koala and Deni have gone somewhere else — and will come back. Cali goes to the airport to see them off; they are healthy; and, I am guessing, Koala lords it over Cali for days before a trip: I get to go on an airplane and I get eggs in the Delta lounge and I get to meet the security team … that kind of thing. Cali knows that Koala isn’t simply ghosting her.
When Jana died after a period with many health problems, Cali’s reaction was completely different. She knew that Jana was gone. She cried and moped and grieved for days.
So, yes, I think dogs do understand different types of separations and have appropriate reactions to temporary versus permanent ones. Though if she did think that Koala was ghosting her, I do not know what an appropriate reaction would look like …
