14. St. Bernard
The Saint Bernards are bulky creatures, large and of important musculature. They have a classic and specific sad expression, although they are incredibly cheerful, gentle and quiet. The typical price is $1600, with toilet costs of about $65. Like any other large dog, size is not necessarily beneficial in terms of health status. The San Bernardos are no exception to the rule: they require medical costs of up to $8600 to treat potential musculoskeletal problems and for regular checkups.
