How Much Should a Saint Bernard Weigh?


The following is extracted from information contained in THE SAINT BERNARD CLASSIC by Albert De la Rie and is shown here as a guide only in a effort to help owners understand the approximate weight they can expect their Saint Bernard to be. Weight can vary depending on bone mass, body mass etc and therefore this is a guide only.

The weight for average saints in the 1950's is compiled by Dr. Henry E. Wedig.
