Hey,
I think that most keepers that own or have owned irascible or surly tempered Bloods of either Malaysian or more commonly Northern Sumatran origin, might be prone to give the kind of anecdotal tale of an animal that was and still is irascible or of one that is now calm and demure and easy to deal with.
In my experience with bloods and short-tails, their personalities can vary, with bloods showing or exhibiting aggression more readily as babies or juveniles, but eventually out growing that kind of disposition with some time patients and lots of conscious handling.
Borneo's on the other hand, can be quite placid and easy tempered allowing for an easy introduction to the Blood and short-tail experience. Their short and stocky builds make them rather ideal if you are looking to get an animal that is both brawny and muscular with a manageable and impressive edge to it, but one that can make for a wonderful experience for the keeper. They are one of my all time favorites and I can't recommend them enough. Their requirements are not that difficult to understand if you have some knowledge of their needs.
Experience as with any thing you aspire to do is key, but that comes with some time and patience. Read as much as possible about what it is you will need to make for a good experience and keeping your charge healthy and you can't go wrong. Do some reading and ask as much about what it is specifically you wish to know and accomplish and you will do fine. Talk to experienced breeders and keepers and read the archives and past and present post on the subject.
However, skimp on the requisite acroutrements such as proper housing and heating and you will in no time short, pay the ultimate price with a sick animal.
