Yes, I linked the wrong manga. I did a quick Google search this morning while I was only half-awake. It's the right artist, and the right title, but the English version I linked is an older version of the story. It does have some girls who are forced to wear dog costumes, but it's more clean and has no TF in it. The comic you're looking for is the newer adult "Remake" version.
I pulled the link because I didn't have time to do a second search for it.
The older version is here:

Note to myself: Don't post when you're mostly asleep. Either that, or I'm getting old.
