Mastiffs are such neat dogs! We had a longhaired one come into the vet I used to work for. I forget the dog's name...but I remember the owners were obnoxious! They had this HUGE dog and lived in the nicer part of town...only had leather interiors in thier expensive cars, and wanted us to pick up the dog for exams! The doctor did so...I'd imagine he liked the $$.

Amazing dogs though!
