4 Signs of an Aggressive Puppy
An aggressive puppy may show several different types of behavior. A few of the warning signs of aggression are:
- 1. Biting: Nipping and mouthing are normal elements of puppy play behavior. Puppies often bite their littermates on the scruff or back of the neck; biting is also a sign of puppy teething. However, play biting turns into aggressive dog behavior when a puppy refuses to stop biting after the other dog signals for an end to rough play by yelping or running away.
- 2. Body language: A puppy reacts to normal play by wagging its tail, bowing (lowering its head and raising its rump), running, and barking. Body language that signals puppy aggression includes deep growling, staring, stiff posture, and ears pinned to the puppy’s head.
- 3. Guarding: Possessive aggression or resource guarding is dog behavior that involves snarling, biting, or lunging over chew toys or dog food bowls. It’s often in response to a perceived threat, which means that puppies might lash out at other dogs or family members who simply pass by their belongings.
- 4. Lunging: Your puppy pulling on its leash when it sees people or other dogs can be normal—or a sign of a potential problem. Lunging might indicate overexcitement or instinctive behavior from certain dog breeds like terriers, retrievers, or Dobermans. However, lunging is a problem when it’s motivated by fear aggression—behavior designed to frighten away a potential threat—or territorial aggression, which is a defensive measure against a perceived invasion of the dog’s new home.
How to Address Aggressive Puppy Behavior
Fortunately, there are many ways to address aggressive behavior from a puppy. Some approaches include:
- 1. Behavior modification: Dog training is one of the best ways to address and resolve aggressive behavior. Obedience training classes with a professional dog trainer can give aggressive young puppies the tools to break bad behavior habits. Professional help from a veterinary behaviorist can also help you reduce puppy biting and food aggression.
- 2. Exercise and mental stimulation: Puppies, like young children, need plenty of physical and mental exercise to prevent the risk of boredom, which often leads to behavior problems. Regular walks, playtime, and puppy training all help to keep a new puppy active, engaged, and out of trouble.
- 3. Interruption: A loud voice or noise is often the fastest way to stop puppy aggression. Use the “no” command in a firm but positive voice to encourage bite inhibition and make noise (such as hand clapping) to distract from their aggressive behavior. Immediately follow up the interruption with a distraction, such as a chew toy.
- 4. Positive reinforcement: Dog owners should always reward a puppy with treats and praise when it exhibits good behavior. Regular positive reinforcement and affection cement the behavior puppies need to exhibit as adult dogs.
- 5. Socialization: Interacting with older dogs is a great way for your pet to learn normal puppy behavior and safe puppy play. Begin socializing your puppy at dog parks, puppy training classes, or in your neighborhood when it’s between eight and twelve weeks of age (and has all its vaccinations).
- 6. Time out. When rough play turns to aggression, remove the puppy and put it in a separate room or in its crate with toys until it calms down. Be firm but calm with your puppy and reward it with praise and treats when it shows signs of normal puppy behavior.
