Here's how to go about Learning the St. Bernard Dog:
1- Study The Breed Standard
2- Learn and study Dog terms
3- Look at many photo's of particular champions, to see what makes them better than some of the photo's you can find here on the Internet, what makes those dog's that have gotten their championships, different than so many of the dog's or puppies you may see advertised.
4-While you study the Breed Standard, remember that the words in that Breed Standard are describing what a good St. Bernard should have, and it will also list some things that a good Saint are not supposed to have too.
5-Learn how to study a Pedigree.
6- Learn about particular Bloodlines, what things they have that are common short-coming through out the dog's in their pedigree and learn what things those Bloodlines are known for that are qualities.
7- There are only two things that will determine the true Quality of any Dog Number one is the Pedigree it comes from and how well did those dog's in that pedigree match up to the St. Bernard Breed Standard, and Number two the Individual Dog and how good does he/she match up to it's Breed Standard.
8- Don't listen to any individual people who seem to be able to talk more about other people or kennels than they talk about St. Bernards. These are people who really don't know this breed, they only know how to Gossip about other people, and for the most part if you are wanting to truly learn this Breed you couldn't care less about Gossip about other people you don't even know.
9- Don't be taken in by Propaganda, promotions of kennel names or Particular Politians, just because they are an Officer (or as the saying goes HIGH OFFICIAL) in some Club, or Clubs.
10- The Breed Standard has everything you need to know or learn about true Quality, and if it's not listed in that Breed Standard then of course it's not supposed to be, so do not add to or substract from the words in the Breed Standard, anyone can understand those words, and learn Dog Terms, to enable them to get a good Mental picture of what a good quality St. Bernard should look like.
11- Do not listen to other people try to tell you their dog's are the only ones correct, there is only One Correct Head and Over All Type and that is the one the Standard describes.
12- Don't even try to listen to people tell you "Well everyone is allowed to interpret the St. Bernard Breed Standard their own personal way", that just simply not true. That may apply to those who would like to think that way but that still has nothing what so ever to do with true quality. True Quality will look like what is described in the Breed Standard, and not just someone's, individual mis-interpretations.
13- Have Fun Learning all about The Great St. Bernard Dog!
14- The Best Book on St. Bernards in my opinion is of course The St. Bernard Classic, by Albert del la Rie, the Swiss Judge Specialist.
