Ironically looking at Steele Personality being this: 
Steele is: The most famous dog in Nome, Steele takes pride in his popularity amongst both the village humans and the dogs, often showing off in front of his admirers. He is incredibly arrogant, often swaggering up to females in the hopes of impressing them with nothing but his looks and reputation. His occupation is highly motivated by fame among both human and animals around Nome. He also likes Jenna, but she sees through his lies and loves Balto the pure-hearted instead, which further strengthens Steele's hatred and jealousy of Balto. He is also dishonest, claiming that Balto and the rest of the team had died, but at the end of the film, when everyone finds out, all of his lies cause him to be shunned and disliked by those who used to respect him. He is mean and sarcastic when he gets on Balto's nerves. He is sneaky, treacherous, envious, extroverted, loathsome, eccentric, temperamental, empathetic, egotistical, very talkative, somewhat of a pervert and energetic as well. He is also heartless, as he prevents Balto and the sled team from returning with the medicine, not caring that the children will die if the medicine isn't delivered.
