Nancy helped me go from thinking I had to put my Pete boy down to being able to walk him just one block with out lunging and snarling at people as well as stop scaling a 9ft privacy fence to attack people walking by. Pete is the white dog in the photo. My shepherd has always been perfect.

We adopted a 7-month cocker spaniel from a Rescue group. Little did we know we were getting a dog with severe anxiety who had not been socialized with humans. After having Rosie for a few weeks, I contacted the Rescue with my concerns and was told that rescues need 3 months to adjust to their new surroundings. Three months passed and Rosie would still spend all day hiding in the corner of a room and only come out at night to pee/poop and trash the house. I contacted a recommended dog trainer and was told that it took 6 months for a rescue to come around. I was told I should just let her alone to decompress. Six months came with no improvement. We then made an appointment with a different veterinarian who told us about Nancy. Rosie's and our lives immediately improved when we started working with Nancy. Initially, Rosie was terrified of everything, but following Nancy's instructions, Rosie started to calm down. It has taken a lot of walking, playing ball, and patience, but Rosie is a completely different dog. A year ago, I was in complete despair because I had a dog who wanted nothing to do with me. Now, I have I dog who wants to sit on the couch with me and loves belly rubs. We were even able to take Rosie to have her picture taken with Santa. I would recommend Nancy to anyone who has a dog with behavior issues.

Nancy has been fantastic in working with us with our Staffy/Boxer mix! He has a history of e-collar training as recommended by other trainers, and Nancy helped us to understand the science behind why the collar was actually making him MORE reactive. She did a very thorough assessment including a written interview form, videos of us interacting with him, and a two hour phone/video meeting. We then met with her in person and she worked with us to teach us how to best address his reactivity, which is based in fear. Her strategies in the house and on the leash have had a major impact in just a few weeks! We can’t wait to continue to see his progress and can’t thank Nancy enough for her calm, kind, and sensible approach!

I reached out to Nancy for help with my rescue dog’s severe anxiety and fear aggression. I’d worked with trainers for years, but he still struggled, especially at the vet. I chose Nancy because of her experience with pit bulls, and we’ve made incredible progress in a short time. One of our biggest goals was helping him tolerate a muzzle for vet visits. Before, I couldn’t even take the muzzle out of the bag without him barking and snapping. After just a month of following Nancy’s plan, I can put the muzzle on him consistently and safely. It has been such a relief. I highly recommend Nancy to anyone needing behavior modification support. She does amazing work!

We were recommended by our vet to Nancy. We reached out regarding our dogs getting into a fight and injuring each other. We had no idea how much more Nancy was going to help us with than we expected. Nancy sat with us and gathered all information to understand our dogs. After speaking with Nancy we found out that our oldest dog is having cognitive decline so she recommended to get an appointment with our vet for a full work up seeing as she looked in pain. We actually found out she is suffering from Cushings Disease. We would have never known one that our dog was suffering worse than it looked and two that the fights could most likely be derived from her pain. I can’t thank Nancy enough for her humility and wealth of knowledge given to my wife and I to help us be educated moving forward.
