I got Smoke from the same pound as Twiggy. He was 9 weeks old. The pound in that little city is very poor, only has outside runs. I couldn't walk away and leave him. At four months, we think he was poisened. With what, we are not sure. It could be snail poisen that was still around the garden from when my mom tried to get rid of the snails, but that was put down two years before we moved over here. So, we just don't know. He had horrible focal seizures which after 5 months stopped. And other neurological symptoms, most of which has disappeared. But it left him slightly brain damaged. But sweet and lovable. My vet has nothing but praise at how calm and gentle he is when getting his shots. At times, it looks like he has headaches, he will squint at me and come on my lap and hide his eyes, but even that is slowly going away. And when he eats, he lifts his left back leg. He does rarely attack other dogs unpredictably, but just a lot of bluster, then he stops like, what was I doing? and wanders off.
