Expert Support for Dogs With Aggression & High-Risk Behavior

You’re here because your dog’s aggression isn’t “just manners.”
It’s changed your routine, your confidence, and maybe even your peace of mind. You don’t need someone to hope things get better — you need someone with real experience handling serious behavior concerns.

At Rosie’s Tail Training, we help dogs and their families navigate the hard, high-stakes work of aggression reduction, emotional regulation, and safer behavior around triggers.


Meet Max Seifert, CDBC — Behavior Specialist Focused on Aggression

For as long as I can remember, I’ve wanted to understand animals- not just teach them tricks, but help them behave predictably and safely in the world. My early experience in horse training and dog-assisted therapy gave me a foundation in reading subtle behavioral signals and managing stress responses before they escalate. 


But it was behavior rehabilitation that became my focus, especially for dogs whose reactions had real consequences:

  • Dogs who have bitten other dogs
  • Dogs owners feared might escalate into a bite
  • Dogs whose reactivity has limited their family’s life- and hurt the 
  • Dogs who are suffering from how severe their anxiety is
     

I developed our Connection Over Control method to meet these complex cases with structure, clarity, and evidence-based behavior modification. 


What Makes Our Approach Different

Safety first. Always.
Aggressive behavior isn’t a nuisance or a funny quirk. It is a risk. That means our work starts with assessment.  Every plan is designed around real-world context, thresholds, and proactive management so you can prevent escalation before it happens.

We don’t promise magic or guarantees- we promise:

  • Clear understanding of why aggression occurs
  • Tools to manage and reduce risk 
  • Practical ways to improve predictability and control 
  • Realistic expectations set with you, not for you
     

You deserve training that respects how serious this is — and how human it feels. 


Credentials That Matter

Max is a:

  • Certified Dog Behavior Consultant (IAABC) — behavior specialization recognized internationally
     
  • Certified Professional Dog Trainer — proven training fundamentals
     
  • Certified Behavior Adjustment Training (BAT) Instructor — science-backed work with fearful and reactive dogs
     
  • AKC Canine Good Citizen Evaluator — reinforcement of reliable behaviors in structured settings
     

But credentials aren’t the whole story. Handling aggression cases requires experience, judgment, and commitment to safety. That’s what every client interaction centers on.


We Work With Real, High-Impact Challenges

This isn’t “puppy class.” We work with owners whose dogs:


✔ Escalate on leash, behind fences, or at the door
✔ Show fear-based or defensive aggression toward people or other dogs
✔ Have a bite history or concern of one
✔ Trigger stress responses that make daily life unpredictable


We tailor every lesson to your dog’s thresholds and your household’s real needs. 


More Than Training — Support You Can Trust

If you’re feeling:

😟 Afraid another incident might happen
😔 Embarrassed by what others see
😓 Unsure how to prevent escalation on walks or in your yard

You are not alone- and there is a path forward grounded in safety and real behavioral change. 


I answer most inquiries within 72 business hours, and every conversation starts with your concerns first.

Frequently Asked Questions

Please reach us at info@rosiestailtraining.com if you cannot find an answer to your question.

We use primarily positive reinforcement-based methods, in alignment with the American Veterinary Science of Animal Behavior's position statement, which can be found here: https://avsab.org/wp-content/uploads/2021/08/AVSAB-Humane-Dog-Training-Position-Statement-2021.pdf


Yes, in fact, that's our specialty. We have helped dogs who have bitten other dogs, dogs who have been declared dangerous, and more. Realistic expectations will be discussed on a case-by-case basis. 


We offer private, in-home training. This means that we come to you, at your convenience. Every lesson is tailored to you and your dog, and we strive to meet you where you are. 


When you call, I'll ask you some questions about your dog's behavior history, and answer any you have about training. If it feels like a good fit, and you're in my service area, we'll set up a free evaluation. 


During the evaluation, I'll assess the behaviors I see, discuss how the Connection over Control framework will apply to your dog, and make a recommendation on the program you should be in. 


From there, we would move forward with training on a schedule that works best for both of us.
