Todays medieval saint is patron of mad dogs!
Saint Sithney – http://hagiomajor.blogspot.co.uk/2011/08/august-4-feast-of-saint-sithney.html or https://en.wikipedia.org/wiki/Saint_Sithney
“A Breton legend says that God chose Sithney to be the patron of girls seeking husbands; the saint begged off, saying he would never get to rest, that he would rather take care of mad dogs than women. Sounded like a good idea to the Almighty, and ever since, sick or mad dogs have been given water from Sithney’s well as a tonic.”
