Helping Dogs Feel Calm & Confident

Aggressive Dog Training in Naperville, IL

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 Naperville, IL.

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.

    We reluctantly decided to try e-collar training after not having the success we desired with only positive reinforcement methods and we are SO glad we did. Our very yappy and reactive miniature dachshund is well on her way to being the pet we always knew she could be. After a very pleasant and informative initial interview with Pauline we decided to proceed with DTE. Grace and Pauline helped us understand and debunk our misconceptions regarding using e-collars. Our in home sessions were with Grace who's patience and incredible knowledge about dogs and training has been amazing. We, Lexi's humans, have been the main training challenge but Grace never made us feel like we were failing. With encouragement and humor she patiently helped train us as much as she did Lexi. We are looking forward to joining the group classes and will update our review as we progress. Thanks DTE for giving us an option that actually worked for our issues! Lexi is quieter and calmer in what used to be embarrassingly chaotic situations. We can't wait to continue this journey with you all!

    DTE transformed Glory, my exuberant 5 mos old Irish Wolf Hound puppy! The staff at DTE took in my enormous, clumsy and eager pup with open arms. Among many improvements, she walks nicely (never thought that would happen), she is crate trained (never thought that would happen), and she is a more confident dog (significantly reduced whining). I always wanted a dog who was a pleasure, and because of the whole staff at DTE, I have one! And our family time with Glory is just beginning!

    We love Dog Training Elite! Our puppy lights up every time he sees Grace, Pauline, and Jamie. They are so patient, knowledgeable, and caring, and they’ve made training such a positive experience for both our pup and us. We’ve already seen amazing progress, and it’s clear how much they truly love what they do. We couldn’t be happier with the training and support we’ve received—highly recommend!

    We love Grace! She’s been such a great trainer for our pup, Pipoca. Super patient, caring, and really knows her stuff. Pipoca is happier and better behaved thanks to her. Highly recommend! From the first picture this is her first time in years that she could be that close to other dogs. I’m so proud🥹

    My dog, Scout, completed the two-week day camp at Dog Training Elite Naperville, and I couldn’t be happier with the experience! Each morning I dropped her off around 8am and picked her up after work around 5:45pm. From day one, she was so excited to go to “school” with her tail wagging, vocal (woo-woo barks), and eager to see her favorite teachers, Pauline, Grace, and Jamie. Scout is a very friendly, eager-to-please “velcro” dog who had a hard time watching me leave at first, but over the two weeks, she gained confidence and independence. The trainers not only reinforced the basics but also introduced new skills. Before camp, Scout was a great dog but tended to be selective about which commands she listened to. Now, I notice the difference instantly. Even on the walk to the car after pick-up, I could start practicing her new skills right away. Walks are smoother, she understands “place,” and she responds so much more consistently. One of the things I really appreciated was how much they involved me in the process. Every day I received report cards, photos, and even personalized videos showing me how to practice commands at home. They also made themselves available by phone whenever I had questions. I felt supported not just during the camp, but in continuing the training afterward. The transformation has been worth every penny. It’s an investment, but for the instant results and the foundation they’ve built for Scout and me, I found it more than fair. Honestly, I almost wish the camp could run in phases (two weeks for basics, a week off, then another two weeks for more advanced skills) because Scout and I are ready for more! If you’re looking for a program where your dog learns, has fun, and comes home happy, balanced, and tired, I can’t recommend Dog Training Elite Naperville enough. And a huge thank you again to Scout’s amazing teachers (Pauline, Grace, and Jamie) for helping us start this journey.

    We loved our experience with DTE! Grace was so great to work with! She was great at not only teaching our dog, Ziggy his basic commands, but also at teaching us how to set him up for success during his training.

    We have just finished our at home classes are excited for group class which will start tomorrow. Grace came out to our home and every class was a success and Sam, my rambunctious 11 month old Labrador was always so excited to see Grace. She was very professional and very friendly. Grace always took the time to answer all my questions and helped out with a couple concerns I had with Sam. He learned quickly and is always excited to work. Dog Training Elite has very knowledgeable owners and trainers and I’m so very happy to have them to work with me and my dog. I’m looking forward to a long relationship with them and they are worth every penny. Also of note, they always respond in a very timely manner whenever you need to text with questions, concerns or scheduling times.

    Pauline and Grace have done an amazing job with our 7 month old puppy after one week. We are impressed with all the communication and videos to help us continue with the training. Holly is always excited and ready to be dropped off, we know she is well cared for. We would recommend with 5 stars!

    I am so so glad I found dog training elite! I rescued my dog Finn and he was having a lot of separation anxiety, having some accidents, and needed some formal training. He has been enrolled with dog training elite for the last week and there’s already been such an improvement! Pauline and Grace have been so kind, compassionate, and informative about his progress! You can tell how much all the staff loves working with these pups! Finn is excelling and the separation anxiety is much improved! I get daily updates, pictures, and instructions on what to work on at home. It is truly a team effort and they are always willing to answer any questions. 5 stars is not enough for this exceptional group! Thank you dog training elite!

    DTE is an amazing, knowledgeable, helpful, and welcoming staff and facility! I started Muffin’s training with them by having her participate in the service dog puppy class and the platinum obedience. She learned so much and I was given updates every day. Now that she completed the camps, we get to participate in weekly group classes to keep up with her training! The entire staff has built a relationship with my dog! I cannot say enough amazing things about them. Highly recommend!

    The staff at Dog Training Elite Western Chicago Facility demonstrated exceptional patience, reliability, firmness, and encouragement during our puppy training sessions, providing a solid foundation for future dog training and behavior. With their vast knowledge and expertise in dog obedience school, they helped us overcome potential issues early on, giving us peace of mind with a well-behaved and well-adjusted furry companion. As we continue towards Service Dog Certification, we have attended the group classes and gotten a lot of good experiences working with other dogs, people and random distractions.

    Please PLEASE do yourself a favor and give Dog Training Elite a call for all your dog training needs. They were highly flexible with my work schedule and always answered my questions. Pauline, Jamie, and Grace are all AMAZING to work with. Informative, professional, and very kind. You can tell these trainers love what they do, and do it well! They all handled my 2 year old female Mal-Shep mix with ease. I swear I picked up a different, more well trained dog each day of her training! Extremely clean facility and seamless communication between all the trainers. When it came to our homework, I was provided a personalized video of the trainer and my dog working on the current assignment AND a fully written assessment on what my dog excelled at and what she still needed to work on. Lady and I thank you for all your hard work and dedication. I will always recommend Dog Training Elite. Your furry friend will thank you :)

    The team at Dog Training Elite Western Chicago Facility demonstrated exceptional patience, reliability, and firmness throughout our dog training journey, providing us with the encouragement and knowledge needed to achieve successful in-home dog. I recently enrolled my puppy, Cooper, in a two-week training program that focuses on basic obedience using an e-collar, and I couldn't be happier with the results! Empathetic and Professional Trainers: The trainers were incredibly empathetic and professional. They took the time to understand Cooper's unique personality and tailored the training to suit his needs. Their approach was gentle yet firm, ensuring Cooper felt comfortable and secure throughout the day. Comprehensive Training: The program was comprehensive, covering all the essential commands like sit, down, come, place and heel. The use of the e-collar was explained thoroughly, and I was reassured that it would be used responsibly and humanely. The trainers provided detailed instructions on how to continue the training at home, which was incredibly helpful. Remarkable Progress: Cooper showed remarkable progress after just a few days. His responsiveness to commands improved significantly, and he seemed more confident and well-behaved. The e-collar was a great tool in reinforcing positive behavior without causing any distress. Convenient and Flexible: The all-day format was perfect for my busy schedule. I could drop Cooper off in the morning and pick him up in the evening, knowing he was in good hands and receiving top-notch training. The facility was clean, safe, and well-equipped, providing a great environment for learning. Video: the trainers post daily videos showing what they are working on that you can view to make it easier to continue the training at home, during and after the program is finished. Overall, I highly recommend this puppy training program to anyone looking to improve their puppy's obedience and behavior. The combination of expert trainers, effective use of the e-collar, and the all-day format made it a fantastic experience.

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.
