I personally would never pay a fee to complete an application! Someone posted not so long ago that SAY does that. I also know a group here for Bostons that does it. I believe it is done so that they can eliminate the ridiculous applications that do come in; but I also believe it pushes some people away. I don't think you will find it with many other rescues, so if you see a pup that tugs at your heartstrings, I would say go for it. I think they just want serious applicants!
That rescue has been around for some time. I don't personally know them, so I cannot really comment on them one way or the other. I do think they are fine..as I said, I just don't know them.
Keep us posted on your search for a new family member!
