Did you get past the soil part that looks like something had recently been buried?
I moved all the objects to the hall. if one needs to use the dog to dig then it doesn't seem to be possible to get it there. if we need a branch or something then nothing either. if the hall door needs to be unlocked then there's no object or object description that can help do that.
if you use a different browser can you finish the game as is? because I'm thinking we may have different versions and we're playing an old one.
