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 2x4 stud with the same loading as above but spaced only at 16 inches does not calc. Shorten that stud to 8 feet long and it makes it, but barely. To get a 2x4 to calc at 24-inch spacing, it can be no longer than 9 feet and support only roof load.
