Right after the dog attacks the bear, it looks like the bear is actually a man dressed up in a bear suit. It is a brown coloured bear, but as they get into the trees, you can see what looks like a man dressed up in a black bear costume and fighting with the dog.
The dog gets attacked by a bear and Pa says that the dog was bleeding pretty good. Then, off camera, they take the dog to the vet. As James runs off to speak to Gideon, there are no bandages or battle wounds on the dog at all.
When Caroline finds Gideon, who has been missing for days, his hair is combed neatly, and his clothes are in perfect condition.
Someone tells Charles that as long as he doesn't mind a little noise, the rooms over the saloon are the best place to stay the night, and Charles agrees.

He wouldn't be so eager to agree to spend the night over the saloon.
When James is calling out for Gideon, modern tire tracks are visible behind and to the left of James.
Laura should have told James how she helped her friend Anna who stuttered.
