gpm,
I have a barn full of 'oldies but goodies' myself, as well as several older dogs I feel obligated too because they were part of my breeding program when I raised dogs and were too old for others to want when I got out of it....there has been continuous loss here for about a year now, most of it in the last couple months...I understand the spot you are in and am not sure what I would/will do when there is only one left...maybe you could find a boarder...this way when yours finally decides to move on you won't be back in the same delima? You know, that looking off into the distance for what has been lost has a kind of Nat Mur sound to it..you may still need to think about grief with her. When we lost our oldest mare to a surgical colic not long ago, all her siblings called all day
I'm sure they knew she was dying...I think it took a couple days for everyone to settle back to normal... I have also witnessed long term grief in horses, for example when my oldest son left home and his endurance horse. She was depressed for months...this was before homeopathy for me, and my solution was to start competing her myself...it worked...do I understand correctly that these symptoms did not manifest till after the loss of your mares companion? That at least would give you a never well since rubric... I think Anna might have brought this up before..... Denise
