That's terrible Chaz.... I'm appalled at their behavior towards Mensa in particular. What is their dangerous breed list, out of curiousity? The usual I presume, rotts, dobes, pitts, chows, and GSD?
Please keep us updated as to any answer you receive back....
So.... dobermans are anti-family.... hmmmm, maybe they forgot to let the breed as a whole know that and the families that keep them...
Edited to add... I did search the traveling with pets area of their website
Tips for Traveling with your Pets Courtesy of KOA Campgrounds , and no where does it say that certain breeds could be resticted. But then when I went into reserving a KOA place then I found a link in regards to certain campgrounds may not allow certain breeds... They sure don't make it very easy to notice.... it is so hidden that I could see how people would view them as (all) pet friendly by surfing their site bc/ that's how they come across at first glance.
