Poodles are highly social dogs who bond strongly with their owners and who, when properly socialized, get along well with children and other animals. However, without proper socialization, poodles may become fearful and anxious. This fear can lead to aggression and fear biting, and poses a danger to owners and other animals. Toy and miniature poodles are especially susceptible to fear-based aggression. Their small size makes them particularly sensitive to rough handling and teasing by children. To prevent anxiety and aggression, poodles should be heavily socialized to novel stimuli, new people and a variety of environments beginning as puppies. Adult poodles with fear problems are more difficult to socialize, but a competent dog trainer can help you properly socialize your dog.
