Puppy vaccines are typically first administered at about six to eight weeks of age, then repeated every three to four weeks until about four months of age. Some of these vaccines might be given together in one injection that is called a combination vaccine.
Pre-Cut Stud: 92 5/8â. This is probably the most common 2Ã4 youâll see at places like Home Depot. Sometimes called a âpre-cut stud,â itâs a little shorter than a full 8â² board, which makes it perfect for building an 8â² wall (hmm?).
The most common spacing is 16 inches on center (OC). This means the distance from the center of one stud to the center of the next is 16 inches. The space between studs that are 16 inches OC is 14-1/2 inches. The first and last studs in a wall are exceptions to the rule. The first stud is shifted over 3/4 inch as its centerline corresponds with the end of the wall, so its side is flush with the ends of the plates.
