This "poor doggie" faggotry is making me smash my bloody face on the table. I hate to defend Cuckmann or his abortion child of a game, but let's make this clear.
You're not dealing with innocent people, we are talking about scavengers and mother-mary-knows-who in the post-apocalyptic world who have dogs that can bite into you/get you killed any given chance. Why would anyone give a shite if the dogs have owners or not when it comes to "you or them" situation? Let's fucking bitch about all the german shepherds who got massacred by Blazkowicz and had their necks snapped in Cock Of Doodie while we are at it, because they are "oh so inherently innocent!"
All I can agree with is that this attempt at guilt-tripping you seems presented poorly with a bad taste, but nobody is telling you to "torture" them dogs, it's not like you're dissecting poor bloke's pet alive and forcing him to watch, for chrissakes.
And all of this is coming from someone who loves animals himself.
