8 uploads tagged with plain xavier tag including:
1) Xave Oto, a brown wolf. Shown post #1532964 (version at FA has Xave in color)(another image of Xave at https://www.furaffinity.net/view/26888884/ )
2) Xavier a black wolf (version 2 partially blue) character of FA username XavierWolf. Changed tag of post #1270211 to xavier_(XavierWolf)
3) one of the characters at post #692723 . No source URL and didn't see at artist's FA. Guessing the xavier is the male dog character.
4) the orange feline at post #581726 . Guessing character of e621 user #104967 (current username Axelboost ) (Axelboost uploaded it to e621 and later added the description)
5) post #501828 tagged with xavier (and "unknown artist"). Both 501828 and post #501667 have similar descriptions at e612
"Quick sketch xavier did. http://shrimpcakestudios.tumblr.com/ "
AND
"http://shrimpcakestudios.tumblr.com/ Xaviers' tumblr"

Since 501667 has artist tag of xavier_(artist) .. changing 501828 to xavier_(artist) also.

That Tumblr is defunct.

so appears they deleted their Tumblr.

https://dukemaximum.deviantart.com/ deviantID section includes
"One of these god awful things... shrimpcakestudios.tumblr.com/"

and their artist style is similar,
so assuming artist tagged as xavier_(artist) still has DA of dukemaximum.

there are two other uploads, but my brain need a rest.

EDIT: The tag alias xavier -> xavier_(disambiguation) (forum #257534) has been approved by @bitWolfy.
