The number of dogs or tamed monsters that may accompany any player will be based on the following equation: (Number of dogs * 3) + number of tamed monsters <= Charisma/2.
Thus, a character with 12 Charisma may travel with two dogs (2*3+0=6, which is = 12/2), or one dog and three monsters (1*3+3=6, which is = 12/2). A character with 18 Charisma may travel with three dogs.
The following changes have been made to dog collars:
Dog collars disappear when dogs die and are not resurrected.
Double-clicking on your dog collar after a server reset will allow you to immediately retrieve dogs.
Dogs (dog collars) may only be transferred between players when the dogs are in a storage facility.
