Toy Poodles may growl and bite due to fear, aggression, or anxiety. It's important to address this behavior early on to prevent it from becoming a habit. One effective way to deal with growling and biting is to redirect your Poodle's attention to a toy or treat. You can also teach your Poodle basic obedience commands such as "sit," "stay," and "come" to help them feel more secure and confident.
