Continuing saga of Sock's tail and Reiki

So...I was treating Sock's tail with Reiki and it seemed to be going really well - he did not seem to experience any pain when he hit it against something. Yipee! The reiki worked! However... being a dog, he chewed his plaster contraption off his tail and then on Saturday night when our visitors came around, got very excited and wagged and wagged his tail still it hit something and started to bleed again! Argghh. So I have not yet re-plastered it but have been administering more Reiki - fingers crossed, so far it seems to be ok. I don't know whether the power of the Reiki will protect it completely so am in two minds what to do. I'll give it a day or two and decide....
