I have come to the conclusion that Bethseda didn't watch too many dogs when they designed Dogmeat. There are a few inaccuracies that been bothering me in a minor way. Not like, it's game breaking. But come from my experiences with both dogs and the few years I worked at a Wolf Sanctuary.
One Dogmeat runs really weird, ever watched a dog in real life or a wolf in real life. To sprint fast, they kick from their back legs. Half the time dog meats limbs are so gangly, and his hind legs so darn scrawny I'm like how does this dog actually run accurately?
Two Dogmeat's nails would not clack on hard surfaces. Wolves claws rarely clack on hard surfaces, I'm using wolves as my example for a reason, point is climbing rocks and hard surfaces keep their nails filed. The only reason our house dogs nail clack on hard surfaces and we need to cut them down or file them down is because they aren't out in the wild, climbing on rocks or hard surfaces all the time. I am sure Dogmeat's nails are filed down considering the whole of Fallout surface is hard, dog meat is climbing on rough, hard surfaces like cement.
Three; Can Dogmeat learn some more tricks besides lifting up his back legs? Come on if we can ask other companions for thoughts, and they have a bunch of different dialogue and comment on the places we are. Can we get Dogmeat some more tricks? Play Fetch with him, I mean actual Fetch kind of like the dog in Fable. Can he play dead when I point my gun's barrel at him? What about actually giving him a treat or something?
