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.
What does the D in D-Day stand for? The D does not stand for Deliverance, Doom, Debarkation or similar words. In fact, it does not stand for anything. The D is derived from the word Day. D-Day means the day on which a military operation begins. The term D-Day has been used for many different operations, but it is now generally only used to refer to the Allied landings in Normandy on 6 June 1944.
