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?).
A similar grade to stud is standard and better. The difference between the two is not so much in the size of the knots or the amount of splits or wane allowed, but in the fact that standard and better grade is used for lumber that is 12 feet and longer while the stud grade is used for 10 feet and 8 feet pieces in grading. The next grade up in quality from stud and standard and better is 2 and better.
