The Plucky Puppy Team

Marley Muffin-Face is the original plucky puppy. Katrin adopted him from the San Diego Animal Shelter when he was a puppy. Without many new or positive experiences during his critical socialization period, he was terrified of everything, especially people. As he was getting used to his new family and environment, Marley showed remarkable strength and courage. With lots of remedial socialization, training, and behavior modification, he eventually adapted to his new home and feline and avian companions. These days he is a composed and confident senior dog who assists Katrin during training sessions.

Plucky Puppy was founded for dogs like Marley, whose spirit could not be vanquished by a bad start in life, and for all the lucky puppies that got everything they needed right from the beginning. We believe that a committed owner—along with ample socialization and effective training—can bring out the plucky puppy in any dog.

A lifelong dog-lover, she volunteered walking shelter dogs as a kid, in college, and most recently as an adult at the San Francisco SPCA.

She and her husband are the proud parents of Cocoa, a ball-crazy, brindle Dachshund-Boston terrier mix.  


Joanna Meleiro unexpectedly found her calling while photographing adoptable dogs for local rescues several years ago. She became fascinated by the process of making the dogs feel comfortable and happy in front of the camera so their personalities could shine for potential future families. After adopting one of her models, complete with a long list of behavior challenges, she dove into the science of animal learning and quickly changed her career plans. She's currently a second year student at The Academy For Dog Trainers and plans to focus on working with the fearful and worried dogs after graduating in 2016.


Sarah Schellhorn, MA, CTC is certified by the Academy for Dog Trainers, which offers a comprehensive two-year course in dog behavior and training.  Dedicated to force-free training methods and continuing education, she keeps current with industry best practices through regular seminar attendance and her professional memberships.  Sarah is an avid believer that training can be fun and rewarding for people and their dogs.  Senior dogs have a special place in her heart, and she enjoys setting up puppies and dogs of all ages for success. After many years working in the field of human behavior, she was pulled to learn more about dog behavior through her love of her Labrador, Violet and later, Bean. Now, she has transitioned from a career in community mental health to work with dogs full-time.  Originally from Chicago, Sarah moved to Portland in 2002. She lives near Mt Tabor with her husband, their Lab, Bean, and a sassy and affectionate cat named Pythagoras.  Sarah spends her free time exploring all her neighborhood has to offer and attending K-9 Nose Work classes with her own canine companion.


Shannon Olsen, CPDT-KA had the unique fortune of growing up with a menagerie of animals in rural Nevada. Following her love of all things animal, she studied Animal Science at Colorado State University. Her passion for dog training grew from applying the relationship-based animal training she had learned working with horses to her own and others’ shy, special needs dogs.  A desire to further understand animal social behavior, learning theory and positive reinforcement inspired Shannon to pursue education through the Karen Pryor Academy for Animal Training & Behavior.  She is also holds Certified Professional Dog Trainer Certification (CPDT-KA) credentials and regularly attends animal behavior and training seminars and clinics.  Understanding the importance of adequate exercise for the successful facilitation of learning and being an avid hiker herself, Shannon most enjoys teaching puppies and young dogs the ways of the world while exploring the great Northwest. Shannon’s personal trail companion is the horse-sized Great Dane mix, Jack. 


Lori Curtin, CTC became interested in dog training after she assisted dog training classes at the East Bay SPCA and Tony LaRussa’s Animal Rescue Foundation. Her passion for dog training led her to pursue additional education, so she enrolled in the Academy for Dog Trainers, a program using positive reward-based training, where she earned her Certificate in Training and Counseling. She trained and enriched dogs’ lives at the humane society and improved their chances for successful adoption.  In the private sector, her goal is to help build great relationships between dogs and their guardians using force-free methods. She is a member of the Association of Professional Dog Trainers and is certified in Pet First Aid and CPR. Lori is owned by two senior rescue dogs, a dachshund mix and a labradoodle, as well as two rescue cats.
