Just back from the Vet's office.
Bosco laid down in the kitchen after dinner last night and didn't move from the spot till this morning when we carried him to the back of the family car.
He was just plain done. Low back/hips completely shutdown and incontinence had become the norm rather than the exception. Like a typical Lab he made nary a whimper or complaint, although I'm sure he was really uncomfortable for some time now.
Goodbye Bosco. You're one for the record books.
