After only a few weeks as a house pet, Togo jumped through the glass of a closed window and ran several miles back to his original master's kennel. This devotion to the team impressed Seppala, so he did not try to give him away again. However, Togo continued to cause trouble by breaking out of the kennel when Seppala took the team out on runs. He would attack the lead dogs of oncoming teams, "as if ... to clear the way for his master". However, one day, he attacked a much stockier malamute leader and was mauled and severely injured. When he recovered, Togo stopped attacking other teams' lead dogs. This would eventually prove a valuable early experience, as it was difficult to teach a lead dog to keep a wide berth of oncoming teams.
