I just checked functionality everything is working fine. Simply type in Maggie in add dam. If your typing in CH Garner's Maggie it probably won't work since its too specific of a name. No need to search titles, breeder or kennel names. Just type Maggie or Mayday, or Jeep and the list gives you plenty of options to choose from.
Also watch this video I give a pretty detailed tutorial on how to get best results when adding dogs
