Fear Aggression Usually Kicks In During Canine Adolescence
Your sweet, docile puppy may not exhibit aggression until he’s close to a year old.
Vicki Hale of Georgetown, California, is concerned. Her seven-month-old Cavalier King Charles spaniel, Kingsley, has been “a very happy dog up to now” but has “started to be a little shy and has also started growling at people he does not know,” she explains.
“I am not sure how to handle this,” Ms. Hale says. “Is he starting to be a little protector?” She adds that he has not been neutered yet and that she would like to breed him two or three times before he is, implying that maybe his being intact is what’s making him aggressive. “What can I do about the growling?” she asks.
