Certified Behavior Consultant For Aggression, Reactivity, Fear & Anxiety


Does Your Dog Have A Behavior Issue?

If so, you are not alone! It is very common these days for dog owners to have a family pet that has behavior issues. It is the main focus of my business. Many of the issues I work with on a daily basis include, but are not limited to:

  • Aggression towards humans and/or other animals
  • Aggression directed towards the owner(s)
  • Reactive behavior
  • Resource Guarding (Protective/possessive behavior)
  • Impulse Control Related Issues
  • Biting
  • Dog to Dog Aggression
  • Fearful behavior towards noises or changes in the environment
  • Fear towards people
  • Anxiety
  • Reactive, fearful or anxious behavior towards a baby or child
  • Hyper-vigilant behavior
  • Compulsive behavior
  • Excessive attention-seeking
  • I am also hired by many clients to help them determine if their dog is safe for them, their household and the public and what the prognosis or future might look like long-term.

You might find that your dog or dogs might be dealing with one or more of these behavior issues.


Certified Dog Trainer, Behavior Consultant or Behaviorist

You might be looking for help, but you’re not sure who to contact for to your situation, right? Are you looking for a dog trainer, behavior consultant, behaviorist or a vet? Do you just need a behavior modification or rehabilitation plan or does your dog need medication to help address these concerns? All valid questions!


In the United States there are actually no regulations on the dog training and behavior industry. This means anyone can call themselves a certified dog trainer, behaviorist, behavior consultant, behavior specialist or aggression specialist. Luckily, there are professional organizations that provide certifications for both dog trainers and behavior professionals. It is important that you find a professional with credentials. The two larger and more popular organizations in the United States are:

International Association of Animal Behavior Consultants (IAABC)

Certification Counsel of Professional Dog Trainers (CPDT)

These organizations provide certifications for both behavior professionals and dog trainers. You can visit their websites to find professional help in your area.


So who do you call?

Professionals labeled as Behavior Consultants (the most popular and widely accepted title), behavior specialists, or behaviorists with credentials are typically who you want to call when you need help with a behavior issue. Some professionals only focus on one area like aggression or separation anxiety, while other professionals work with a variety of issues.

Dog Trainers are considered to be different. Basically all behavior consultants are dog trainers but not all dog trainers are behavior professionals. This is because to work with behavior issues one must have knowledge about how a dog learns, why they might display the behavior(s) they display and how to properly address those concerns, whether it be with a behavior modification plan or medication provided by a qualified veterinarian or board certified veterinary behaviorist. Whereas Dog Trainers focus on providing dog’s with basic skills, foundation skills and life skills such as obedience and manners as well as tricks, sports or high level work.

Meet Anthony De Marinis

I am a Certified Dog Behavior Consultant (CDBC) by the International Association of Animal Behavior Consultants (IAABC), a high-level industry-leading behavior certification. I am also an Accredited Dog Trainer (ADT) by the International Association of Animal Behavior Consultants (IAABC). I enjoy continuing my education in training and behavior modification. Currently, I have obtained seven professional certifications as a result of my dedication to helping dogs and their people.

There is nothing I enjoy more than helping dogs and their people build strong relationships. I find it to be an incredible experience to be a part of a dog’s life. My practice covers a wide range of training and behavioral needs, regardless of the dog’s age and breed. Whether you need help with a new puppy or are looking for assistance with a behavioral issue, I can provide you with practical guidance and solutions that best fit you and your dog’s needs. I like the challenge of creating a plan that provides each dog and their people with helpful solutions to assist them in reaching their goals.


My Approach

My approach is simple: I train dogs the way I train my own dog. In particular, I believe in taking a kind and compassionate approach when training and modifying behavior, using positive reinforcement methods.

Positive reinforcement means rewarding your dog for doing the right thing, rather than inflicting physical force, intimidation, or fear tactics that weaken the relationship between the dog and owner.

I embrace this method of dog training because, more than anything else, we need to be our dog’s teacher and guide in life to help them become successful. Whether training or modifying behavior, our goal should be to teach, manage, and guide our dogs so that we can prevent and/or resolve issues. Teachers and guides do this by teaching skills and boundaries using clear and consistent training.

Training and living with your dog should be a fun and enjoyable experience that forges a strong relationship between the both of you. My methods are always compassionate and fair to both the dog and their people.

What About Behavior Medication?

If you feel your dog needs internal help with behavior or anxiety medications you should seek out help from a qualified veterinarian. Specifically you could seek the help of a board certified veterinary behaviorist which is a veterinarian who specializes in working with animal behavior issues that typically require medical interventions. To seek out a board certified veterinary behaviorist take a look at these two organizations to find a qualified professional in your area:

The American Veterinary Society of Animal Behavior (AVSAB)

American College of Veterinary Behaviorists (DACVB)
