I wanted to introduce myself as a new member. My husband and I have a 12 year old female red and white Basenji. Her name is Sienna. Her health is excellent, but we wanted some information from other parents of "senior" dogs. I've read that the average life expectancy is 10-12yrs, but Sienna is so vibrant!! With the exception of a little bit of arthritis and a kidney stone removed two years ago, she is just great. If anyone has an older Basenji, Sienna and I would love to hear from you.
