There is nothing wrong with the Eberspacher It has, however, been possessed by an evil spirit. You will therefore need to perform an exorcism although I must warn that this can be traumatic for the poor Eber.
You will need to find a reputable exorcist. These are regulated under the new "Exorcim Act 2007". The exorcist invokes God and/or several different angels and archangels. The Priest also uses Crosses and Holy Water often when performing one.
If it still does not work you can report the Exorcist to the Exorcism Ombudsman who in our new multi-polar society lives in the 6th Dimension.
