A Board and Train Program Built for Serious Aggression Cases
Not every dog trainer is equipped to work with an aggressive dog, and not every board-and-train facility should be.
K9 Mania Dog Training’s Aggressive Dog Board and Train program is a dedicated track within our Long Island facility, reserved for dogs showing human aggression, dog-to-dog aggression, resource guarding, fear-based biting, or reactivity that private lessons and other training programs haven’t resolved. Your dog boards on-site in Deer Park under the direct supervision of our team of certified professionals for the full length of the program, so behavior is addressed consistently, safely, and without the distractions of home.
If your dog has bitten, lunged at, or shown aggression toward people, other dogs, or family members, this is the program designed for that level of risk, with the safety protocols and expertise to match.

How Our Aggressive Dog Board and Train Program Works
Because aggression cases carry higher risk, this program starts with a formal evaluation and follows a more controlled structure than our standard board and train.
Free In-Depth Evaluation
We assess your dog's triggers, bite history, and behavior in person before we enroll them into our program.
Custom Behavior Plan
We build a training plan around your dog's issues, not a one-size-fits-all obedience program.
3–6 Weeks of Training
Your dog trains daily at our Deer Park facility under constant, controlled supervision with our team of certified professionals.
Go-Home & Owner Coaching
We train you alongside your dog with hands-on handoff sessions so the results hold at home and in public, not just at our facility.

AGGRESSIVE DOG TRAINING FREQUENTLY ASKED QUESTIONS
Common questions from Long Island owners
Pricing depends on the recommended program length, the severity and type of aggression, handling requirements, and your dog's individual plan. You receive an exact quote after the free in-person evaluation and before enrollment.
Yes. Our team is trained to handle severe aggression and has worked with hundreds of bite-history cases. We start with an in-person evaluation to understand your dog’s behavior and create the safest training plan.
Aggression cases typically run 3–6 weeks. The recommended length depends on the dog's behavior, history, training goals, and progress rather than a one-size-fits-all schedule.
Board and train is often the best option for aggression because it provides daily training, consistent structure, controlled exposure to triggers, and 24/7 supervision. We begin with an evaluation so the program can be tailored to your dog’s specific behavior and needs.
K9 Mania has helped dogs make significant progress in even severe aggression cases, but lasting results depend on owner consistency after graduation. That’s why we train you, too, and provide continued support through phone and email, refresher sessions, and advanced group classes to help you maintain your dog’s progress for life.
Every K9 Mania Board and Train program is customized to the dog. For aggression cases, training focuses more closely on the dog’s triggers, behavior patterns, safety, and responses around people or other dogs. Owners also receive hands-on education and continued support to help maintain progress after the dog returns home.
The program may use structured management tools, including a slip lead, prong collar, or e-collar, when the training team considers them appropriate. Ask during the evaluation which tools are recommended for your dog, why they are being considered, and how you will be taught to use them.
The program includes owner coaching and go-home guidance so you understand the handling, routines, warning signs, and management plan. Continued practice at home is essential because residential training does not replace the owner's role.
