If the dog is wet and shivering, then it's shaking because it's cold and needs to be dried off and warmed up. If it hasn't been running or playing or been wet or cold, then you need to take it to a vet, immediately. It could be any number of diseases or toxins, and you can't help it if you don't know what it is.
The Supreme Court of the United States. The Supreme Court of the United States is the highest court in the land and the only part of the federal judiciary specifically required by the Constitution. The Constitution does not stipulate the number of Supreme Court Justices; the number is set instead by Congress.
The Judicial Branch. Article III of the Constitution of the United States guarantees that every person accused of wrongdoing has the right to a fair trial before a competent judge and a jury of one's peers. Where the Executive and Legislative branches are elected by the people, members of the Judicial Branch are appointed by the President and confirmed by the Senate. Article III of the Constitution, which establishes the Judicial Branch, leaves Congress significant discretion to determine the shape and structure of the federal judiciary.
