When you put two or more words together and they name a particular person, place, or thing, then you have created a proper, compound noun that ACTS as ONE single word.
One Proper noun: Scotland + common noun: police + common noun: dog, ETC.
Scotland Police Dog Training Center = a proper compound noun, and is one...word.
Welcome to the Five O'clock News here on Channel 285.
The Scotland Police Dog Training Center announced today that it will be giving away free puppies to the first twenty people who come to the centre on Wednesday morning, when it opens its doors at eight o'clock.
None of the words in the proper, compound noun modify any other word in the name. They are used as one word. How can one word modify itself?
"...the parts of a compound noun may be written as one word, as two or more words, or as a hyphenated word."--Warriner's.
prizefighter, newsstand, news room, sister-in-law, Belmont Square Memorial Hospital, The Prudential Building, etc.
All treated as one word.
It doesn't mean a proper noun, one word or compound, cannot act like an adjective to modify a noun:
The Yellow Cab Taxi Company car was totally demolished in the accident. Fortunately, the Yellow Cab taxi driver survived with minor injuries. A Yellow Cab spokesperson held a news conference about the accident at the company's headquarters.

Note: the topic of "hyphens" is another thing altogether with its own rules for all kinds of compound words--nouns, verbs, etc. These rules often apply to compounds not found in a dictionary.
