There are exceptions to every rule but it is my opinion that pups being hot or not doesn't determine wether or not they will be a Bulldog. I've owned hot pups that acted as good a man could ask for and even though they were sat on ended up nothing more than rank curs. With that being said I've also owned dogs that as pups were hot and ended up being solid adults. In my honest opinion wether a pup is hot or not, all it means is you have a good acting pup or a laid back pup, nothing more. When the time comes the real truth will come out. Cream always rises to the top.
