we were given one previous (4 years old) owner said he was going to shoot it took it in fine with dogs of its own size our jack went up to it then it grabbed our jack by the throat then pushed it around like a dyson it took three of us to get it off (squeeze of the crackers).in my mind unpredictable with true bull bred into it you have your opinion i have mine.having five dogs from a rotti,lab,lurcher and two jack russells all get on.this dog may be from bad breeding or training i would not have another as a gift.
