Let's look at the following example from a shelter I'm working with:
Page one shows the required housing for adult small dogs. Page two, large dogs. As you can see, a cage is defined differently for a small dog and large dog. Large dogs (not Chihuahuas in this case) are given an entire double-sided guillotine run. Small dogs are paired together (if they came that way) and are given one side of a run. Based on the numbers, by dividing out small dogs and large dogs in statistical analysis, we can better estimate the number of cages necessary for handling the required stray holding capacity for this shelter. Then, based on the number of cages, we can better determine the number of staff hours needed to clean these kennels. Note, I break out adult dogs because puppies are a whole other story that I'll talk about some other time.
