So it looks like Dogmeat has been replaced by our robotic canine: Cyber-Hound Mk. III, LEO Support Model, Serial Number B955883, or as he is better referred to as Rex. Clocking in at 209 years old, he's developed a distaste for hats... and the people that wear them. Also note that Companions now have accompanying perks as well!

The Mojave Wasteland is a dangerous and desolate place… so you feel the need for some companionship during your adventure. Like Fallout 3, New Vegas allows you to have one humanoid and one non-humanoid companion at any time.
