No. They don't. Not even similar enough to be in the same genus. You mentioned those "minor anatomy changes". They shouldn't all occur within the same genus.
If you shaved both wolves and Bichons, they'd look a lot alike. Bichons are just morbidly inbred dwarf wolves with genes that encourage wooly white hair and floppy ears. Floppy ears are often found in domesticated animals.
I nevertheless feel confident in saying that if one shaved off the outer later of latex appliqués one would see compelling anatomical similarities between a Xindi-Reptilian and a Xindi-Primate.
