Dusty

Dusty was one of the tertiary characters on People I Know. He had one major appearance in Season 1 and started being more important in Season 3.

Dusty was a conscious, rebellious dog, who over time gained a worthy relationship with Vašek.

Biography
Dusty had been previously owned by Mrs Kopečková. In "Dusty's Moving On", he moved into a flat on the opposite of Vašek's house and presumably resumed living there from that point on.

At the end of "The Legacy of Dusty", he is transfered to a pound after commiting harsh crimes. In the very next episode, "School Underground" Dusty saves Vašek's life in the end by sacrificing himself. It's revealed that Vašek put his body on a cementery and regularly visits him there with a flower.

Personality
In the early episodes, Dusty was portrayed as a carefree dog, who although shared similarities and intelligence with a human person, enjoyed lowbrow activities and never really cared about anything. Even when he was in the background, he was always portrayed as careless and only appeared at parties.

Dusty goes through a major personality change after Season 3. In "Dusty's Moving On", he moves out of his ex-owner Mrs Kopečková's house. While he's still enjoying party life, it is noticeable that he reached his point of maturity and is capable of stronger thoughts and emotions.
