Welcome to Mason Dixon K9, we’re excited you’re here! We understand finding the right trainer for your dog can feel overwhelming.  There are a multitude of factors to consider including certification, location, training techniques, comforts (will my dog be taken care of as if they were at home), and so much more.  

Is Mason Dixon K9 Experienced? When training and handling dogs, experience matters. Since 2003, Founders Ryan and Sandy Bulson, have been helping families and various organizations to rescue, re-home, track, and train more than 300+ dogs, including litters of puppies, seniors, medically challenged dogs, and dogs with severe behavioral issues. Coupled with a full staff with equally impressive backgrounds in training and caring for various dog breeds, the techniques and knowledge they have cultivated during the 20+ years of experience is unparallelled.  The Mason Dixon K9 team's hands-on experience makes them unequivocally the best at what they do.

Mason Dixon K9 Expands, Full-Service Resort of Hanover, PA
Opening Soon!

Friday, February 16, 2024

As we make progress on the renovation of the resort to Pennsylvania and Maryland inspection certification code and licensing requirement standards, unforeseen circumstances have forced us to open the doors slightly later than originally projected.  

Just like you, we are beyond eager to open this new, fully renovated, full-service facility, and are now aiming to open around May 1.  As with any renovation to this magnitude, certain issues presented themselves that provided no other option than to address the issues properly. Mason Dixon K9 (MDK9) has high expectations and standards that are not only in-line with, but also exceed Pennsylvania and Maryland inspection certification code and licensing requirements, therefore in order to meet and or exceed those standards, we are not taking any short-cuts, or speeding through a renovation of this magnitude which could jeopardize the health and safety of any staff or animal at the facility. Unfortunately, taking the right approach comes with the cost of delays. 

We are doing everything we humanly can to get there, but doing it right is most important and we greatly appreciate your patience and understanding.  We will be opening a separate Facebook Page with updates and information and look forward to sharing photos of the progress soon!

There is much work to be done, and we know the transition period might present some challenges to current Paws Pet Resort customers, however, Mason Dixon K9 Crew and Family will work with you to ensure as little disruption as possible during this transition.

Effective immediately, Mason Dixon K9 Management will be assuming full responsibility of the resort and assessing what needs to be done in order to re-open with Mason Dixon K9 facility management, standards, protocols and more.  Mason Dixon K9 prides itself on the level of care and high standards that we have established, and we need to ensure that the new facility adheres to those expectations.

We are asking for current Paws Pet Resort clients to kindly work with us during this transition.  Once the facility is up and running, the services will remain the same, thus expanding Mason Dixon K9 current services to include those previously offered by Paws Pet Resort.

Once again, the Mason Dixon K9 Family is wagging their tails in anticipation of what’s to come…and there’s a lot more to come!
