Sorry to hear it. We had Hobbes, our 14 year old Mastiff mix put down in September. Not a good feeling. I felt like we sold him down the river because he could still wag his tail, but in the end I know he couldn't walk anymore (he was 105lbs.), and it was for the best. He is on our mantle with a photo I took the day we had to have him put down, handsome as ever. It is like losing a member of the family, I'm sure like Hobbes, Popeye was loved and well taken care of and thats what matters. I will now go upstairs and look at my old boys photo, thinking of the good times.
