 So to go back to the actual problem this dog had, I wonder how many people need to know about this. In Jake's case, saliva built up because this tumor obstructed his ducts, D-U-C-T-S. And I wonder if that happens to other dogs that have the same kind of a problem. Is it likely that you're going to have a problem with certain breeds that don't have the ability to clean themselves out as much as you'd like to?
