Thanks for posting and informing everyone of this; I know there are several people out there that wasn't aware that dogs could mourn a loss and I am one of them. I can't imagine how your friend's dog and bird must be going through after losing their companion of 14 years. That is a very long time and I know they must be wondering where they are. I wonder if dogs know that if their their loved ones are deceased or just currently away. Or does that even matter? I have had a dog pass away but I have never had more than one dog at a time, so I wouldn't know what it is like to be around a dog that is in morning. My boyfriend and I were thinking of adding another dog to the family and now I know all the signs to look for in case something happens to my animals.
