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 purpose of the Judicial branch is to fulfill the mandate of the Constitution to the effect that every person has a right to a trial by jury in front of a competent judge. The Judicial Branch is comprised of the Supreme Court, United States district courts, and United States courts of appeals. All of these are Federal courts, and can make decisions concerning interpretation of the law that are binding on lower courts.
