It may be a combination of infection, if the pruners were not sterile, and damage from an animal. The infection can be made much worse, much faster, with excessive rain.
You will want to treat with fungicides anytime that you see that the tree is declining. Keep all dead leaves and debris away from the area.

As for the bark- This looks like deer damage. Protection will be the only solution.
