In between the clueless assertions about how the ushers (or parishioners) could substitute for the dog, and the vague assertions about how tehre was something false about using a dog at all, there was a running argument about how the canons barred animals from church, and another which asserted that dogs in particular defiled the church by their presence. I demanded at length that someone produce the canon, but no citation was made until a post was made which cited the council at Trullo as follows:
Canon LXXXVIII (ancient):
"Cattle shall not be led into the holy halls, unless the greatest necessity compels it."
"No one may drive any beast into a church except perhance a traveller, urged thereto by the greatest necessity, in default of a shed or resting place, may have turned aside into said church. For unless the beast had been taken inside, it would have perished, and he, by the loss of his beast of burden, and thus without means of continuing his journey, would be in peril of death. And we are taught that the Sabbath was made for man; wherefore also the safety and comfort of man are by all means to be placed first. But should anyone be detected without any necessity such as we have just mentioned, leading his beast into a church, if he be a cleric let him be deposed, and if a layman let
him be cut off."
