Dog
A towering guardian of scrap and steel, built to protect the one person who means the most to Eli Vance.
Dog is a massive, fully mechanical robotic construct created by Dr. Eli Vance as a companion and protector for his daughter, Alyx Vance. Unlike typical pets or standard military assets, Dog is a towering construct of scrap metal, designed with immense strength and unwavering loyalty to aid the Resistance in their fight against alien invaders and oppressive human forces.

Lore & Background
Dog's relationship with Alyx Vance transcends simple command and obedience; it is a bond forged in shared survival and mutual care. He acts as Alyx's steadfast guardian, capable of dismantling Combine armor with his bare hands or shielding her from overwhelming odds. Despite his monstrous appearance, Dog displays profound intelligence and emotional depth, often pausing to ensure his friend's safety before engaging enemies, serving as the heart of the Resistance's most dangerous operations based out of White Forest.
In Their Own Story
The air in City 17 tasted of ash and ozone as the Combine dropships screamed overhead. Gordon Freeman paused behind a crumbling concrete barrier, reloading his crowbar with practiced ease. Suddenly, a shadow fell over him—not from the sky, but from the ground. Dog rose up, his metallic plating grinding against rusted gears, eyes glowing with a fierce, protective light. Without a command, the giant beast lunged forward, tearing through an approaching Strider's leg with a sickening crunch of metal and bone, shielding Freeman as the alien fire rained down.
Reader's Guide
Dog is not merely a pet but a living weapon of mass protection designed by Dr. Eli Vance. His role is singular: ensure Gordon Freeman survives to continue the fight against the Combine. He possesses superhuman strength, capable of ripping apart heavy armor and lifting vehicles with ease, alongside enhanced durability that allows him to withstand significant damage. His arc begins in Episode One as a newly activated asset, proving his worth immediately by saving Freeman from a Strider ambush. Over time, he evolves into a trusted partner, displaying tactical awareness and deep loyalty. His defining moments include single-handedly turning the tide of battles that would have overwhelmed human forces alone. Dog's power lies in his physical dominance and unyielding spirit. He serves as both a tank and a shield, allowing Freeman to focus on precision strikes while he handles brute force threats.
