Denizens of Heaven are the deceased of all mortal species, residing in the celestial plane. They are first tagged in Open Up The Pearly Gates, although they appeared earlier as "innocent bystanders" in the Not All Dogs arc.
Their appearance is highly variable due to the psychological nature of their home. They are also capable of instantly locating individuals through thought. Most of the denizens seen in the comic are non-human mammals, although this may be partly by choice.
She appears only briefly in One Person You Meet In Heaven, recognizing Fox instantly. She very closely resembles Bailey.
This is King's mother (also appearing in One Person You Meet In Heaven), although only her silhouette is visible. She is not surprised to find that her son is in the form of a corgi, although it does appear to have caused her to lose some sort of bet.
Two husky girls that Fox met after his first week in heaven, who accompanied him for the remainder of his visit. They seem to have become infatuated with him and tried to contact him several times after he returned to Earth, but due to his being in Australia at the time and wanting to avoid roaming charges, he hung up without answering. They also appear to have added green and pink buttons to his bandana. In The 4 Animals You Meet In Heaven, Summer gives Keene a letter to give to Fox. Fox finally reads it in Real Stories of the K9PD which tells him they will be visiting soon...
Breel is a pine marten that runs a massage parlor staffed by various heavenly mustelids. When Keene Milton had a near-death experience in Heaven in The 4 Animals You Meet In Heaven, Breel guided him for much of the arc. He is shown to have developed a fascination with Keene. Later, in Temple Crashers 2: Temple Crashers, Part 1, Breel comes to Earth to make sure Keene doesn't do anything stupid at Pete's temple.
Rufus is Peanut and Grape's pet-cousin, an elderly dog that died at some point, and went to Heaven. He was among the denizens who came down to Earth in Temple Crashers 2, largely helping Peanut and Grape's party.
