I have a 1 1/2 year old male dachsund Kipper who has bitten twice. I have had Kipper since he was 8 weeks old, he was spayed at 4 months. The first time he bit was at a dog sitter's home at the age of 9 months. Her son (12 year old) opened the kennel and he jumped out, growling and bit him. The second time was this weekend. My nephew (5 year old) went to the back yard, bent over to pet Kipper, and he bit him.
I have two childen ages 5 and 6 and Kipper has never shown any aggression towards them. My husband suggests that we find another home for Kipper as we do have children visit. I want to address this behavior but don't know how.
