The new dog model is EXCELLENT. It even has a properly modelled mouth and teeth this time. Kudos to whoever made the model. It's lovely.
However, the animation is horrendous. The person who animated the dogs clearly has no idea how a dog moves and holds its tail. The tail especially looks broken in the middle. I've seen it holding the tail up and down and in both instances, it has a distinct break in it. A dog's tail bends in a smooth curve. Unless someone's run over it. A happy or relaxed dog holds its tail up or down close to the body with a smooth curve. This poor beastie desperately needs a vet!
It runs like a rabbit. Please find someone who knows how dogs move and make some new animations for it. Like whoever did them for Dogmeat in Fallout 4. He moves like a proper dog.
I love dogs as much as cats (which ESO have done right), but so far have not bought one in the game because some are missing teeth and tongues and the animations are simply horrible.
RIP Atherton, my beautiful little gentle friend. I will miss you forever. Without you I am a hollow shell.
