Bark Busters Home Dog Training Loudoun and Fairfax Counties

Best Dog Training Leesburg VA, Fairfax, Winchester and surrounding areas in Northern Virginia.

Hello and welcome to Bark Busters Northern Virginia, serving all of Loudoun County and most of Fairfax County.

I am Mark Renshaw, a certified Master Trainer/Canine Behavioral Therapist who has owned and operated Bark Busters Northern Virginia for approximately 15 years. Having been one of the very first offices to open in the United States, I have proudly trained over 5,000 dogs in this region. I empower owners to be the “leaders of the pack” and communicate in a non-physical approach, simply using body language, tone and timing that dogs instinctively understand. I train in and around the home where behaviors manifest and ultimately need to be addressed and resolved to have a much happier well behaved dog. ANY DOG, ANY AGE ANY PROBLEM!

I have significant experience working with dogs of all ages who have serious behavioral problems. My Northern Virginia dog training is simple and amazingly effective! I can provide training for

Aggressive dog behavior

Basic dog obedience

Destructive chewing


Pulling on the leash

Puppy training

Separation anxiety

Toileting in the house


And much more!!!

Bark Busters Home Dog Training Services

The Bark Busters Home Dog Training Methods helps solve dog behavior issues such as aggression towards people or other animals

  • Cure embarrassing habits like barking, jumping up on people, scratching & whining at doors or inappropriate toileting.
  • Create an obedient dog or puppy that will happily walk on the lead without tugging, sit or stay on command, and come immediately when called.
  • Set off-limit areas for your dog.
  • Reduce the stress of separation anxiety without the need for sedatives or drugs.

We teach you to communicate with your pet.

Blah, blah, blah, bad dog! blah blah. Do you think your dog isn't listening to you? Maybe you're simply not speaking his language. You may have heard of dog whisperer or dog listener techniques. The Bark Busters dog training method is based on the way dogs communicate with each other and how they learn from older, more important dogs in the pack. This is what makes our dog training unique and effective.

Why do we train in your home?

Your dog lives with a family, in a home. This is where he misbehaves most often so this is where training is most effective. Dogs learn by association. Bark Busters teaches your dog to listen in the home environment. If he does not listen at home, he will not listen outside your territory.

Training in your home is a one-on-one system without the distraction of other dogs or the stress of being sent away for training.

Of course, where you are experiencing problems outside the home such as pulling on the lead or dog aggression, we will set up controlled training situations in the park or wherever is most practical.
