I don't know who else here on CS followed the adventures of this all-loving dog and his owner on Youtube. Sadly, Sherpa was found with numerous tumors all inside his body, and only one thing could be done. I am literally crying over this like he was my own dog.
I'll miss seeing you bringing delight to your owner and any other strangers you wanted to make friends with. May your wait for your owner in heaven seem like a short one.
