Teller is a new arrival that we took in with a slightly younger male, Penn, who is likely his son. We have video of them playing and hanging out together, so they're compatible but don't necessarily have to be placed together. Given how much they each enjoy the company of another dog though, we think they would be happier in a home with another compatible dog. Teller would be a better candidate to accompany a female dog, since he appears to be the dominant dog of this pair. We think Teller is about 2 years old, and he weighs 75 pounds. He was tested for Von Willebrand's Disease (bleeding disorder that occurs in some Dobermans) at the time of neuter and is not at risk.
