The link is the website of Steve Cook, who co-created the song with morning DJ Jack O'Malley at WTCM and the dogman story out of whole cloth in 1987. It explains when, how and why he wrote the song, played it on the station, and how it took off.
A quote from the front page:
"...Choosing characteristics of Bigfoot, the Boggy Creek monster from Arkansas, the Jersey Devil, and several other 'cryptids,' Cook created a mythical half-man, half-dog, and wrote several verses about appearances of the creature. He placed the events in Northern Michigan towns, and gave the dogman a mysterious chronological nature. Each sighting occurs in the seventh year of the decade.
“Everything in nature is cyclical,” states Cook, “bird migrations, the seasons, locusts; I picked the seventh year simply because it happened to be 1987.”
It then of course goes on to tell us that while they 'made it up', it then 'became real'(?!?)... but then, the front page is dominated by an ad for the 20th Anniversary Legend of the Dogman CD/DVD set for only $20.
Hhmm, couldn't really get $20 for that if they didn't let the story 'become real' I guess.
