EXCLUSIVE

If you love dogs and you love "American Idol" ... then you just missed the opportunity of a lifetime,  because David Cook unloaded his Hollywood mansion -- and it came with it's own customized DOG YARD!!!!

The Season 7 "Idol" champ recently sold off his Beachwood Canyon pad -- which has a killer view of the Hollywood sign -- for a cool $1,365,0000.

The 3,000-sqaure-foot house is pretty amazing too ... it's rockin' 3 bedrooms, 2.5 baths, wrap-around decks, and a FULL recording studio.

But best of all, it features a specially-designed dog yard -- which non-dog owners would call ... a yard.

UPDATE: We realized you might need a refresher on who David Cook is ...

You're welcome.
