Meet the Pack

Jonathan Wong has built his reputation as the East Bay's dog trainer for complex behavioral cases. Based in the East Bay and serving Oakland, Berkeley, Richmond, and surrounding communities, Jonathan combines technical expertise with exceptional communication skills to help families transform their relationships with their dogs.

Jonathan's real skill isn't just training dogs—it's connecting with people. He specializes in challenging cases, from aggressive dogs and severe anxiety to resource guarding and complex behavioral issues, always prioritizing human safety above all else.

Many dog owners come to him with misconceptions about human-dog hierarchy, and Jonathan excels at managing expectations while finding the right fit for each person's current abilities and life stage. His diverse East Bay clientele includes busy working parents, renters dealing with noise complaints, elderly couples, and families with young children.

As a regular instructor at Pet Food Express Pinole, Jonathan makes professional training accessible through both group classes and personalized in-home sessions. His philosophy centers on realistic expectations and genuine care: every situation deserves thorough assessment, every family deserves to feel safe and confident with their dog.

Vivian is the co-owner of Pack Leader Dog Training and manages home-based dog boarding for past and existing clients. She provides individualized care in a calm, peaceful environment. Dogs enjoy daily belly rubs in the living room, walks through beautiful May Valley neighborhood, regular feeding schedule, clean water, play time, and photos sent to clients on their dog's day. (She happens to also be a photographer and artist, so don't be surprised if you receive a portrait). Pack Leader Dog Training's boarding program is highly sought after by families who want peace of mind that their dogs are being cared for by dog lovers.

In August 2024, Jonathan and Vivian met Raymond at a Contra Costa County Animal Services adoption event in Orinda. Originally named "Bochy," this black Pit Bull with honey colored eyes had been overlooked by most adopters—despite his friendly temperament with dogs and gentle nature with children. Jonathan saw what others missed: potential.

Now Raymond serves as Pack Leader Training's demo dog, proving that even dogs from difficult backgrounds can achieve remarkable behavioral transformation. Raymond's composed, assertive energy makes him ideal for working with reactive and aggressive dogs. His calm presence helps de-escalate situations and allows dogs to practice appropriate social behavior in a controlled environment. Whether you adopted a shelter dog with unknown history, a rescue with behavioral challenges, or a purebred with aggression issues—transformation is possible. Raymond proves that breed doesn't determine behavior - training and understanding do.
