I had a wheaten X Russel,years back,great bitch to work but very intense,I was about to put her to a good Russel dog in the end of her third season but she died in ground before she broke down,had her sister too but at 15 months old ,pulled a cat off her kennel wall and ate most of it,dead 2 days later ,....had their dam here,she was a savage,parted with here as all she wanted was to kill my other dogs,good in the country though...
