Helping Dogs Feel Calm & Confident

Aggressive Dog Training in Fitchburg / Leominster, MA

One of the most difficult, necessary, and rewarding behaviors to correct in a dog is anxiety and aggression. These behaviors can be learned, genetic, or innate. When a dog feels threatened, their natural response is either fight or flight.

Most dogs will try to distance themselves from the perceived threat; if that's not possible, they may resort to aggression or submission. Some dogs, particularly those who see themselves as confident pack leaders, may turn to aggression as their first response.

Both of these reactions are rooted in anxiety and can be effectively addressed with Dog Training Elite's balanced aggressive dog training in Fitchburg / Leominster, MA.

Understanding Aggressive Behaviors in Dogs


Read More
Read Less

Aggression is one of the most concerning behaviors your dog can exhibit. If left unchecked, an aggressive dog can pose a serious threat to family members, strangers, other dogs, or even themselves.

Many dog owners struggle with how to recognize early warning signs of aggression or how to effectively address these tendencies. Identifying and managing aggressive behavior early on is crucial in preventing it from escalating into more dangerous situations.

Common signs of aggression in dogs include:

  • Growling or bearing teeth
  • Threatening barks
  • Standing rigid and/or taller
  • Raised fur
  • Nipping and biting

Aggression often stems from underlying issues like fear, anxiety, improper training, or negative environments. Dogs that have been rescued from poor situations or found on the street are particularly susceptible to developing aggressive behaviors.

At Dog Training Elite, we specialize in professional dog training for aggression, helping your dog transform from fearful or aggressive to a happy, friendly, and loyal companion.

    Marcus and the DTE team (shoutouts to Matt F, Alaina, Josy and Laydon!) have transformed our rescue girl, Siri. We started this spring and have just seen her confidence blossom. Anytime we grab her e-collar, she gets super excited. Walks are much more enjoyable for us. She loves her trips to Home Depot. We look forward to continuing on in group classes as we further work on her socialization and desensitization skills in various environments. We also are considering certification in AKC’s Good Canine Citizen program as another goal because we also love doing this work with her to strengthen our bond as owners and handlers. We have worked with a handful of DTE’s trainers because we needed flexibility for crazy schedules, sometimes we would have hoped for more continuity between the trainers as we did get some weird conflicting info a few times. We also were grateful for them letting us expose her to their dogs and work through areas. Would love if there were even more group classes options in both days/times and locations. The outdoor classes could also benefit from having a mic with Bluetooth speaker as you can be pretty spread out and sometimes difficult to catch instructions.

    5+ Stars to the entire team at Dog Training Elite! From the very beginning, the staff has been professional, responsive, and reliable. Scheduling is always prompt and the guidance and support have been consistent every step of the way. After working with several trainers in the past and hitting a plateau with our fear-reactive shepherd/husky mix, we reached out to Dog Training Elite feeling borderline desperate. It has turned out to be one of the best decisions we’ve made for our dog. The expertise, especially with working breeds, has been incredible. The trainers not only helped us address reactivity toward people and other dogs, but also focused on building our dog’s confidence with new skills like placing in tricky spots and doing “doggy push-ups.” Training finally feels fun again (for all of us)! We were unsure at first about working with multiple trainers instead of just one, but quickly realized how consistent and supportive the whole team is. Special thanks to Marcus for helping us choose the right program and always being there with support, and to both Matts, who gave us a new level of confidence in how we handle challenging situations. Between one-on-one sessions and group classes, we now feel prepared to safely and positively bring new people and dogs into our lives (see picture with his new friend

    I highly recommend DTE Central MA! My fiancé and I started lessons with them when my German Shepherd puppy, Rio, was around 3 months old. He’s now 8 months old, and working with DTE has helped shape him into the best young dog. We’ve done private sessions with Marcus, Matt F, and Matt K, and each trainer has provided a ton of knowledge and help. They come right to your home, or meet in public for real-life scenarios. Scheduling has been easy. They’ve covered obedience, shaping polite behavior, and even scentwork. We’ve also attended several group classes in several fun locations, and they structure the exercises really well.

    Patrick was very knowledgeable with a nice approach when evaluating our 14 week old pup Duke. He provided several tips on training with focus on positive reinforcement while creating a healthy bond. He also gave nice compliments about our boy and any parent just eats that up with pride. Thank you!

    Our puppy is one of the best trained dogs because of Patrick at Dog Training Elite. I love that the trainers come to our home and work 1:1 with the dog in our/his space. Less distractions and very practical applications. 10/10 would highly recommend.

    Great information in regards to our puppy training. In addition to the leave game, Patrick suggested to use a treat tray or lick it mat to help with engagement games as well.

Our Personalized Aggressive Dog Behavior Training

At Dog Training Elite, we understand that every dog is unique, and we have developed a comprehensive training program specifically to eliminate aggressive behaviors across various breeds.

  1. Initial In-Home Assessment: We begin with a free in-home assessment where we meet your dog to understand the underlying causes of their aggression, anxiety, or fears. During this session, we identify triggers and gather the necessary information to develop a personalized training plan.
  2. Personalized Training Plan Development: Based on the assessment, we create a customized training program tailored to your dog’s specific needs. This plan targets the unique behaviors and triggers that contribute to their aggression.
  3. Building Confidence and Establishing Leadership: Our trainers work closely with you to establish your role as the pack leader in your home. For fearful and anxious dogs, we focus on building confidence and reducing the fears that trigger aggressive behavior.
  4. Desensitization and Obedience Training: For overly aggressive dogs, we use desensitization techniques to reduce reactivity to triggers and anxieties. Obedience training are key components of this stage.
  5. Group Class Integration: Once your dog reaches a safe baseline of obedience, we gradually introduce them to group class settings. These classes are designed to help your dog reintegrate into social environments successfully. For safety, a muzzle is required during these sessions to protect all dogs involved.
  6. Ongoing Support and Reinforcement: We continue to support you and your dog throughout the training process, offering guidance and reinforcement to ensure lasting success. Our goal is to help your dog become a loving, loyal, and well-behaved member of your family.
