What did I miss about Edan? Can some one point out the post for me?
I believe the post Cheryl is referring to regarding Edan is this one:

Quick summary is that nearly two years ago (it'll be 2 years in February specifically) we had to PTS our 17 year old Finnish Spitz, Melody. Mel was 15 when we brought a 7 month old Edan home so they didn't really play or interact very much so we were caught off guard by how much he missed his big sister.
He essentially shut down - didn't get the zoomies through the house, wouldn't play with his toys (his favorite was the Kong Wubba), would just on the floor or on his pillow and look mopey. The only time I saw a glimmer of the 'happy Edan' was at Agility practice. While this improved a little after about 6 months, during visits with the breeder and his original pack, he still really didn't want to run and play.
Fast forward to this year. We brought CJ home in April as a companion for Edan in the hopes that our 4 year old would start to act like a 4 year old and have some fun. In November, during our Thanksgiving visit to NJ, Edan started to chase CJ around the yard - it was a MAJOR breakthrough since this was the first time they engaged in any sort of play. In the weeks leading up to Christmas, Edan's play drive has increased and want to play fetch and tug and wrestle. He and CJ still need to work out the "play" signals indoors but its getting there.
So, now that I've derailed this thread explaining the origin of Cheryl's question

, I'm going to add my one two cents to the discussion. (I've only tried to write this three different times already.)
Dogs definitely feel grief, depression, and loneliness; I've lived it with Edan for the past two years. Some come back from it faster than others and some need a little help; either medical or companionship.
Does having the vet come to the home to PTS your dog's companion make it easier on them? Honestly, I don't have an answer for that. In some ways it makes sense but, in others, I have to wonder if we are imposing human emotion and logic on the animals.
I'm NOT trying to discount the experiences some of you have had with your animals regarding the passing of their companions. Its very touching to see them react in this way and does reinforce the fact that we don't really fully understand the psychosis of our animal companions.
Personally, I'd have to say it really depends on the animal. We all know that every one of them has a different personality; more withdrawn, outgoing, playful, diva, etc. Those individual personalities probably play a factor in how they handle a companion's passing; which is really the same for us - we all handle grief differently because of our personalities.
