Ok... so here are the pups that have been claimed and still need to grow...
Shy

Metallic Dragon

These are the pups that heavily lean on who they belong to, yet owners have not spoken up. 2 are clear indicators that they belong to the artist.
Vampiric

("lotl" hint in her only hint given. She also has a pattern and style *as seen in many of her past pets*, but do not go off of style and pattern alone. She is one of very few that changes only a little.)
Yağmur

(In one of her few hints, she mentions that the pup has an aura of some kind. Since growing to 2nd stage, this pup has shown the aura. How much it will retain is unknown to us, but to the artist.)
xem

(Given that his only monthly pets all have the stripes *pup has rings like a tree that's been cut* and floral items on them, and the fact that this is his first staff pup, all similarities point to this staff/artist)
Final 2 pups are not decided upon, but out of the ones left, one can only guess that they belong to the last 2 remaining staff... Sixbane and Kazin.
Sixbane

Kazin

Kazin's and Raire's we got so mixed up on until Raire's sweet and toothy pup finally grew.
These are what I feel are correct and as I have watched staff and GH come and go, I feel confident on about half of what is left... especially Vampiric's pup.
