B,
I have 2 female JRT's and I have to say, I think they were very easy and quick to train and are very intelligent. They are also so loving and want to be with you at all times.... Mine even sleep with me !!
Personally I think most people believe the bad stereo-typing that they get, for example;
#1- They're hyper - False
#2- They're hard to train - False
#3- They're not good with kids - False
#4- They're snappy and aggressive - False
#5- They're cat killers - False
#6- They don't get along with the same sex - False
And I could probably name off a lot more horse crap I've heard about them. None of it being true.
I'm sure that within every breed there is a few bad ones in the bunch, but it certainly isn't fair to say that it's true for the whole group.
Sassy and I went to both Beginners Obedience and Advanced Obedience and she was the STAR of both classes !! (I just had to brag)
