i like this idea and also for it to go hand in hand with the wolf for sale button being added to individual wolves on people's dens would be amazing. I am sure someone has said that before, but it would be better for them to both be implemented to prevent too many unwanted/unsolicited emails about getting access to wolves. Even showing the locks on wolves on dens after the search has been implemented would be nice so that if we go to a den after a search we can visually see that the person has locked the wolf to their account already.
