thats the way to be Im affraid, A bad or retierd dog takes as much room and food as a good one, if you look on them as a pet thats diffrent all together.
I understand what your saying But if this animal in question has put its back out, gave all it had Everytime you were out then it deserves to be with you until its not anymore in my opinion
if ya have had a dog for that long its past its sell by date its obviously still there for a reason so it deserves to be there till it dies true dog men would know this shite dont get kept
