From what I have seen southerner, is it's all in the nose, no matter what type of breed. Some dogs come on fast, others it takes 2 or 3 years for the light to really come on. Black and Tans seem to take the longest. Walkers the quickest.It also depends on how much time you are willing to spend working with your dog's. If you see a breed you really like the look of, gas it, is my opinion. All dogs seem to learn better from older dogs. Just put in allot of time with them and have lots of patients. And from what I have seen out of Curs they lean toward a HOT nose. You can make a dog out of any breed if you work with them.
