Round 3: Survivability
Unlike the other companions in MGSV, D-Dog really sticks to you the entire time you’re out in the field. As such, this makes it extremely easy for you to give DD orders anytime you need it. You can get D-Dog to perform lethal sneak attacks on unsuspecting enemies, or you can get him to distract enemies while you sneak around them.
D-Dog can hold his own in a fight. It’s entirely possible for D-Dog to actually die from taking too much damage, but at least you’ll know he died valiantly. For you. For the mission. For glory and honor.
Dogmeat can also fight enemies. The only problem is, Dogmeat only knows how to charge straight up at enemies and attempt to chomp them. Dogmeat is extremely flimsy, and it won’t be long before he collapses on the ground, whimpering, and begging you to save his worthless life with a stimpak.
No, Dogmeat. I’m not using a stimpak on you. You barely did any damage to that feral ghoul and you want a stimpak? No.
Well, to be fair, I guess Dogmeat does do a good job of distracting enemies while you take potshots at them. Of course, you also have to be careful not to shoot your own dog because, well, he keeps getting in your damn way. So even when Dogmeat’s keeping your enemies busy, it’s hard to even get shots in without hitting him at some point. Goddammit Dogmeat.
