Sven is affectionate, loyal, and playful. He loves going for walks and rides, he loves playing with bubbles and chasing water from the hose. Sven is absolutely hopeless at playing catch but will play tug-of-war for hours. Sven is anxious and unpredictable around other dogs, hates cats with a vengeance, and hasn't had much exposure to other animals (although he's had no interest in my daughter's pet crabs or mice). He is unpredictable, anxious, and even aggressive towards unfamiliar children (although he's been wonderful with our three kids). Sven is house trained, knows how to sit, come, lie down, and stay on command. He doesn't sleep in a crate and has free range of the house when we're gone. He doesn't get on beds or furniture.
