Please change the rank to loners, they are all stray dogs. So you either need to put one of the pack ranks (pup sitter, mother (which is inly temporary until pups are a certain age), pup, hunter, warrior/guard, omega which is not a bad thing here) or loner.
Also please put sexualities for them since it is an essential part of any form so people know what your dog (or human but there's no humans here) is into.
