I’ve owned 2, knew quite a few more. The female was a sweet thing but ancient and sick when we got her..I still miss her. The male decided he was my mom’s dog and growled at me every time he saw me. Never mind that even as a 5’2” female I was many times his size, he was ready to take me on...poor silly beast.
I still never had to lift a hand to him, and it kinda baffles me that anyone would. She’d just tell him to “Go lay down!” in that tone of voice and he’d slink off.
Yes our dog is not mean as we would not allow it. We have worked with her to curb that natural tendency to chase bikes and joggers etc. They are just prone to do it. They are just feisty little dogs. But such great companions.
