Mine were all mixed but for two Siamese. The only one who really freaked was a long haired, dark calico, Miss Pitty-Pat, but she was kind of freaked out a lot anyway and it was just that she didn't like it when I tied their leashes to a line between two trees, so they could all walk at the same time. At the time it was not funny, but looking back we had a laugh. She got loose with her leash on which caught on one of the carriers, so it was bumping behind her, as she ran through a forest of closely spaced trees, which scared her even more. Fortunately, the carrier got caught between two trees and I was able to catch her. All the while the others calmly watched from their tethered lines, with the dog!:-)I never tried that, again!
