Why Is My Wheaten Terrier So Aggressive?

Wheaten terriers are soft and cute, but like a storm on a hot summer day – fierce and aggressive. There’s one thing that many soft-coated wheaten terrier owners can agree on, and that’s the breed’s aggressive behavior can be quite concerning at times. Understanding the reasoning behind soft-coated wheaten terrier’s aggressive behavior can help reduce or eliminate their rebellion.

Fear / Anxiety

While soft-coated wheaten terriers may seem all big and bad when they’re attacking people, other dogs, etc., they are actually scared – very scared. Unlike other reactions to fear, they fight rather than flee.

Any threat that your pup perceives can turn into a fight. It doesn’t matter if that threat is children, other dogs, cars driving by, the postal service member, etc. It’s the perception the threat is going to do something to harm either your pup or family that can get trigger the aggression.

Separation anxiety is common among soft coated wheaten terriers. This is one of the most common reasons people as: Why is my wheaten terrier is so aggressive? They are known to attack the door when their owners leave.

High Energy

The terrier breed is known for their being energetic. That’s many people decide to get a terrier. The energy can be fun, but it can also cause problems like when your dog tears up the bed.

When high energy causes problems, that’s when dog owners ask: Why is my wheaten terrier so aggressive?

Instincts – Genetic

Soft coated wheaten terriers are born that way. Just like people, wheaten terriers have a long history of being reactive. The good news is that even though we all may be born with personality traits, we can work to change them.

Negative Past Experiences

Dogs with negative past experiences will often become reactive dogs. If you adopted your pup from a shelter, it’s likely the reactive aggression comes from negative associations formed in the previous home. This could be due to abuse or neglect.

Attention Seeking

Wheaten terriers demand attention and if they don’t get it, they will do what they need to do to get it. That includes being aggressive.

How to Decrease Aggressive Behavior in Wheaten Terriers

The best thing you can do to decrease aggressive behavior in your wheaten terrier is to hire a dog trainer. Professional dog trainers have the training and skills to turn the behavior of an aggressive dog around in much less time than doing it yourself.

While working with a dog trainer or if you’re interested in trying it yourself, keep the following tips in mind.

Positive Association vs. Punishment

Punishment can fuel reactive aggression. As your doing obedience training with your terrier, work diligently to produce positive behavior associated with certain situations or triggers. When there’s a positive response, provide a lot of praise and treats.

Repetition is key here as the more positive association there are, the faster your terrier will understand what not to do.

Claim Dominance

Reactive dogs believe they are the leader of the pack. They need to protect themselves and pack no matter what. That dominant behavior can be reduced by showing your pooch that it’s not needed because you’re the one that is the pack leader.

You can do that by teaching commands such as stay and sit while there is a trigger around. The dog will then watch what happens and see that you are in control.

Attention for Positive Behaviors

One of the biggest mistakes terrier breed owners make is falling prey to constant attention-seeking behaviors. When your pup is bad, do not pick him/her up, distract him/her with playtime, or go for a walk. That’s rewarding the behavior. Instead, provide attention when your pup does something good and ignore it when doing something bad.

Wear Your Pup Out

The best way to train a dog is when exhausted. Be sure to run your pup in the backyard, provide puzzle toys, and work with your dog to get him/her tired before starting training with your terrier breed.

Expose Puppies to New People

The more puppies are exposed to new people, the less of a threat they will become later. Just be warned that wheaten terriers are renowned bouncers, so warn people about it until the behavior is under control.

What to Keep in Mind About Terrier Breeds

Just because your puppy is aggressive, it doesn’t mean that terrier breeds can’t be good family pets. They make good family dogs as long as they learn what to do and not do.

Just like children, they need to learn the right and wrongs of being a family member. After they learn how to behavior appropriate in a family unit, they make a great family dog.

When Buying Terrier Puppies

If you stumbled upon this article because you want to purchase soft coated wheaten terrier puppy, be sure to keep these tips in mind:

  • Puppy mills are NOT recommended for any dog breeds. They are not healthy and cause problems because shelters are overrun with dogs needing forever homes.
  • A pet store is also not a good place to look for puppies. Most of the puppies come from puppy mills.
  • Breeders have healthier environments, but they also contribute to the increasing problems in shelters worldwide.
  • Shelters have a bad reputation for having bad dogs, but that’s not always the case. Shelters rehabilitate “bad dogs” by working on them – obedience training and behavior modification – before making them adoptable. You can find great family dogs in a shelter, including wheaten terrier puppies, adult dogs, and older dogs.

    Blonde is our 3rd dog who we’ve had for almost 3 years. She had been rehomed a couple times and is a runt. She’s my special needs one. My other dogs: a 10 year old toy poodle is joy cool and Bella is a Lagotto Romano, aka my Italian girlfriend.

    Blonde goes all Rambo when her trigger is tripped. I can bring her down (sit and soft massage around the ear) most of the time, but if the other dogs go off all bets are off.

    Anyhow in her past life he had training, but it left a mark on her spirit. You say “stay” and you’d swear someone did her wrong. she’ll sulk away and go lay under a table. It breaks your heart.
