<quoted text>What happened scarecrow? I dont feed my dog that junk from china,but i have never heard that a microchip which is the size of a grain of rice can cause cancerous tumors.Many dogs have been returned to their owners because of those chips.
My big male dog was fine the Saturday before Thanksgiving. Sunday he stopped eating. Monday he couldn't get up. We took him to two vets and and spent a bunch of money trying to save him.
He had cancerous tumors on his liver and spleen. The one on his spleen ruptured and caused internal bleeding.
Google microchips and tumors and Chinese dog food and tumors.
