Brownie, a 12-year-old mixed-breed dog owned by the Wilcox family of Klamath Falls, reached its 11th year of being ignored Monday. 'The first year or so we had Brownie, we paid a lot of attention to him and played with him constantly,' father Mitchell Wilcox said. 'But after that, the novelty of having a dog wore off, and we all started to ignore him, even the kids. Now, I suppose, we're just waiting for him to die.' Experts predict that Brownie will tolerate two to three more years of disregard before attacking a family member, at which time he will be declared senile and euthanized.
