The vast majority of judges are very adept & are able to judge a dog shown in either direction. There are very few in the time I have been showing(nearly 30 years) whom have requested dogs shown the other way round to face in the 'normal' direction & those have been foreigners.
Show the dog in which ever direction is his best side....markings can give an optical illusion which sometimes make it look like there is a fault.
I have 2 bitches whom I show opposite way round on the floor but not on the table. This being as sometimes the mat is stuck to the one end of the table.
