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.

Fin was able to learn basic commands in a timely manner and Pauline was always very patient and kind with Fin. Can’t recommend her enough!!

    Paulina, Jaime, and Grace are amazing ladies! They were so patient with Benny as he was very anxious attending facility classes. Hes been so much better with his obedience, behavior, and commands. He loves classes as much do I. The classes are so much fun, Benny is tired after class. I love how the girls change it up every weekend with different challenges. They put in a lot of hard work, love, and effort in Benny. Appreciate you all!

    My 7yo dog and I have worked worked with several trainers through out the years, and the group at DTE in Naperville has been my favorite. They really listened to what it is my dog and I were looking to get out of the training and work so that their program fit our situation! Grace does a phenomenal job listening f to the owners and reading the dog during the one on one session!! Cannot wait to go join the group classes.

    The team at DTE have been fantastic helping us work with our anxious Rottie. I am very grateful I found them because he is doing better already. It takes time and patience but it is worth it.

    Excellent facility. As with any training, it’s really what you do at home that makes the most difference. DTE gives you the tools to make that difference!

    We found DTE after looking for additional training support when one of our dogs attacked our other dog. It was a beyond stressful experience for us, but when I first reached out to DTE, the owner (Katie) was so kind and patient and empathic as I shared our concerns and she shared the training options. We just completed the in-home training program with Grace, and are looking forward to starting the group component. Grace has also been extremely kind and understanding. She is extremely knowledgeable and always ready to answer our questions and provide any additional direction. We are so grateful for Grace's help and guidance, and our dog has shown incredible growth in terms of his response to our commands. Our deepest thanks to Grace and DTE

    We love going to the group classes they offer. We had a great time Saturday in downtown Naperville walking the river walk. It was a great teaching lesson for Holly with all the people and distractions that were around. Holly is doing so well with the training she gets from Pauline, Grace and Jamie. At almost one year old we are so pleased at all she has learned. 5 Stars all around!

    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.

Our Personalized Aggressive Dog Behavior Training

Read More
Read Less

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.
