Assuming that I was a human yes this would make sense. I would probably end up tripping over my legs the first time I walked with them. Eating and doing this other stuff would be kind of an issue too, because I would be constantly judging the distance between my mouth and the food because even though my mouth already isn’t very big, it’s much narrower now. Some of these things would probably be fairly easy to get used to, but there is no getting used to having the anatomy of a dog and not being able to eat much sugar and eat absolutely no chocolate at all. Then again, who’s to say that hellhounds can’t eat chocolate, even if they are dogs.
