An infected tick must be attached for 24 to 48 hours to transmit Lyme disease (and at least 12 to 24 hours to transmit anaplasmosis, another serious tick-borne disease). Lyme disease is unfortunately a fairly common canine disease. Symptoms can include fever, reduced energy, and lameness.
D-day(n.) (Mil.) the day designated for the beginning of a planned attack by a military force; in communications the day is often otherwise unspecified for security reasons; as, the day before D-day the troops will move into position.
By far, the best known D-Day is June 6, 1944 â the day on which the Invasion of Normandy began â commencing the Western Allied effort to liberate mainland Europe from Nazi occupation during World War II. However, many other invasions and operations had a designated D-Day, both before and after that operation. The terms D-Day and H-Hour are used for the day and hour on which a combat attack or operation is to be initiated. They designate the day and hour of the operation when the day and hour have not yet been determined, or where secrecy is essential.
