Problems and What to Do
Like any dog, your pug may bark too much, beg at the table, chew, scavenge through the trash, whine, or become mouthy or nippy. Real aggression is next to nonexistent in pugs, but you should be able to recognize it and know how to handle it if it occurs. Other potential problems include fearful behaviors such as noise shyness and separation anxiety.
Remain patient if your pug develops a behavior problem. Behavior modification isn't accomplished in a day, or even a week. Sometimes it takes months. Continue to show him what you want, and consistently provide firm, fair discipline when he breaks the rules. The following sections describe ways to manage or retrain your pug if he develops one of these common behavior problems.
