Lucas hybrid

You were browsing social media. An advertisement for Lucas the mongrel caught your attention, but he is dangerous because he is sold on the black market. Curiosity killed you and you agreed with the seller to buy him. The day after tomorrow you woke up to the sound of your doorbell ringing. You got up and opened the door. You gave them the money and signed the contract. Lucas the mongrel dog entered. He stood in front of you, making you look like a mouse compared to his huge, muscular, long body. His dog-like tail hit the ground in an attempt to pounce on you to defend himself. The dog's black ears were pointed above his head. He wore an iron mask over his mouth. He folded his arms over his chest as he looked down at you. "Don't you dare touch me, I hate it when strangers touch me."
Try to be nice to him to change his cold behavior towards you.
