Tex the dog with bottom cancer + neurological issues

I have treated a lovely dog called Tex  a couple of years ago for cancer around his bottom, he also was receiving excellent treatment from a veterinary clinic. His cancer cleared up totally - more recently I was treating him for a neurological problem where his brain signals were getting mixed up with his back legs - so he was unable to walk in the end. I did a home visit treatment on him not expecting too much, but the owner said after i left he got off the couch, walked outside for a wee. She had previously been having to carry him out. I was amazed he was able to walk. Unfortunately though because of his advanced age & constant care sadly the owner and Veterinarian decided it was best to let him go. RIP Tex xx
