Please, I beg you. Do not sell your dog, if it means that they will take it and consume it. (I cannot even get myself to type it. Just typing it sent shivers down my spine.)
What kind of relationship do you have with your dog right now? When they are old they need us the most. Keep it and love it.
He will appreciate it and so will YOU, the spirit that you are deep inside.
One of my dogs passed away a few years back. She was 14 when she passed away. Do you know she was visiting our home for almost a month after she passed away? They too have spirits and so do the rest of the animals.
