I realized this morning before dawn when I had to get up to help Zeke off of the floor (he was doing his unhappy bark) to go outside that he wasn't his old happy self, and hasn't been for a while, so I made the call and took him to the vet this morning to euthanize. I let the next door neighbors know and they came over to say goodbye.
The universe spoke, in a way: as we drove off Beethoven's Ninth was just starting and was our accompaniment for the drive. I stayed with him till the end but wasn't there long, and when I left the Ode to Joy was just starting. Joy defined his life for almost the entirety of it.
Now to wash beds and rugs and floors and put the den into order. I can put furniture back where it used to go before I had a dark dog struggling through narrow passages (or sleeping in them - a tripping hazard of the first order). That harness I put on him yesterday was a huge help, we were able to move him through the clinic with some dignity and more comfortable for him. The rest of the recent purchases can be donated, and his senior dog food as well (the other dogs don't like it as well as their own.)
