Allie Gohery

Allie is a self-proclaimed crazy dog lady. She lives in Newton with her wife, Fiona, and four dogs: Lena, Flip, Alfie, and Belle.  A lifelong animal lover, Allie began professional dog walking in 2012 when she started working for Durty Harry's Brookline. After deciding to sell the store in 2015, Allie continued on with Durty Harry's Dog Walking. Allie and Jenny spent months talking about how they could make a difference in the walking business, and enrich the lives of the dogs they worked with each day. Thus, their idea for The Happy Dog was born. Allie holds a bachelor's degree in Political Science from Boston University. In addition to managing The Happy Dog, she works at Boston Veterinary Clinic as a veterinary technician. Allie is Fear Free Certified and incredibly passionate about the Fear Free movement in veterinary medicine!

Jenny Efimova

Jenny is a Karen Pryor Academy Certified Training Partner (KPA CTP) and a Fear Free Certified Training Professional. She came to dog training after more than a decade working with human survivors of trauma. She owes this life-changing adventure to her rescue dog, Larkin, who taught her that animals, much like people, require compassion, dignity, and agency in order to live healthy and enriching lives.

Jenny understands firsthand that the type of training we choose will not only inform our relationship with our dogs, but will impact their emotional and physical wellbeing for years to come. For this reason she is committed to using only the most modern and ethical positive reinforcement techniques that go beyond “basic obedience” to build life-long skills for dogs and their humans. 

Jenny holds a Bachelor’s Degree in Psychology, and a Master’s of Public Administration from Northeastern University. She earned a certificate of excellence for completing Living and Learning with Animals, a comprehensive course focusing on the technology of applied behavior analysis.

Jenny is the founder and owner of Dogminded, and serves as a volunteer trainer with PittieLove Rescue Inc. Jenny is a training member of The Pet Professional Guild, the Association for Force-Free Professionals.
