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.
Western and Mountain Bluebird boxes should at least be 5 x 5 inches to 5 x 5 inches to accommodate their larger clutch sizes. Mountain Bluebirds need an entrance hole of 1 9/16 while Western Bluebirds use a 1 hole. In case the ranges overlap, it is best to use a 1 9/16 hole. Oval holes should only be used in Eastern Bluebird boxes with moderate to small dimensions to reduce the possibility of Starling use.
