General terms and specific terms are not opposites, as abstract and concrete terms are; instead, they are the different ends of a range of terms. General terms refer to groups; specific terms refer to individualsâbut there's room in between. Let's look at an example.
For medium-size dog breeds, considered a whelping box that is about 28 to 34 inches long by 28 to 34 inches deep. Large dog breeds need whelping boxes that measure about 42 to 45 inches long by 34 to 40 inches deep.
Making the world better, one answer at a time. It all depends on what the post will be used for. In general 30 to 36 inches should be adequate to support a 4x4 post for a clothesline, a fence or a mailbox. Anything less than that and you most likely will have a problem with frost moving or lifting the post to the point where it will not be straight in the spring.
