I cannot say enough positive things about my experience working with Nikki Esser & OC Service Dogs. Her knowledge and passion shine through so strongly when you see her working a dog, your dog, my dog, and with her “human students”! She is able to connect with the animals and their humans in a way that helps create amazing teams. Whether you are looking for a service dog / program, an obedience program, or a therapy dog program -look no further, you have found the place! More...

Nikki knows her profession exceptionally well. Service dogs, behavioral issues, all ages, and breeds. I can't say enough about her professionalism and caring. Her assistants are great too.

We love OC Service Dogs! We have been going for 1.5 years, from the time our puppy was 4months old (that was when we adopted him) until now--we continue to go for reinforcement and new training ideas. Topics covered include training strategies and general care for both puppies and adult dogs. OC Service dogs tailors the activities you do in class to your dog's training level and it's great to have older dogs help teach puppies and vice versa! Thanks for all you do OC Service Dogs!

I participated in both the group classes and a private lesson. Both were very helpful and exceeded my expectations. The group classes are great. They have a mix of dogs at various levels of training. The open forum style is practical and it allows everyone to ask real world dog behavior questions. I highly recommend OC Service Dogs for anyone looking to learn more about dog training and have a good experience with your dog. More...

Nikki’s training has been fabulous for me and my dog, Quincy! This didn’t come natural to me at all, but teaching my dog to please me has become a fun challenge. I wouldn’t take my dog anywhere else. More...

OC Servicer Dogs and Nikki are top notch! Nikki makes class so fun for the handler and the pooch. She is professional and very knowledgeable about her field of work. She helps so many people with their service animals and personal pets. I highly recommend OC Service Dogs for all your training, and questions. More...

OC Service Dogs is run by Nikki Esser, a highly-experienced, professional, and compassionate dog trainer who specializes in training all kinds of working dogs, particularly service dogs and therapy dogs, but also offers obedience classes that are open to all dogs.

I first interacted with Nikki over the phone when she responded to my inquiry about how to go about obtaining and training a Service Dog to help mitigate the everyday challenges I face due to my disabling chronic illnesses. Nikki has supported me through the whole process, from obtaining a dog (she recommended a fantastic breeder who connected us with an excellent Service Dog Candidate), to potty training and getting through the first hard months of obedience training, to task training, to phone conversations about questions and issues, and beyond. We are still in the training phase, but I have no doubts that she will support us through to certification.

I highly recommend the group obedience classes (she offers these three times per week) for dogs of all ages. They really helped my Service Dog in Training get used to other dogs and focusing on me despite being surrounded by distractions.

Private Lessons are another great option for folks who need individual attention to work on specific tasks or have difficulty training in a group atmosphere.

Nikki also offers combination boarding and training, which has been very helpful for keeping up my Service Dog's training when I am feeling under the weather, training tasks, or working through complicated issues that I cannot solve on my own.

You will not find a more empathetic, kind, or thorough dog trainer than Nikki Esser. Contact OC Service Dogs, you will not be disappointed!

We love OC Service Dogs! Nikki helped us learn how to navigate training a puppy - by training ourselves first. Nikki is so patient with both pets and humans, and I gain so much value from weekend classes!! We get compliments every where we go with how we'll behaved our dog is - and classes are always fun and so helpful. From bitting/nibbling, to jumping on you, to walking on a leash without pulling you, Nikki helped us learn how to communicate to our dogs, what we want from them. She always leaves time for questions which is so helpful to hear both the questions others have and Nikki's answers. We also left our pup with OC Service Dogs for a weekend and were so relieved finding a solution to not having someone to take care of the pup. Our girl even heeled better after her weekend with them! Can't wait until we're at the next class possible (and neither can the pup and thank you for taking such good care of Dax!! More...

We ABSOLUTELY LOVE OC Service Dogs! We have learned SO much from Nikki in such a short time and enjoy her upbeat personality. She is very experienced with training dogs AND their people. It shows in her ability to work with every dog she meets and to customize her training techniques to best fit the dog/handler team. She provides us with many opportunities to take extra field trips to Malls, ride trains, go to beaches, parks, playgrounds, practice agility training and so much more. She is passionate about helping others by providing the highest quality experience available. Whether you're training a pet, a Therapy Dog, or a Service Dog, we highly recommend for you to train with Nikki. More...

"Nikki has a very special connection with dogs which in my opinion is amazing. Avalon my yellow Lab will be 1yr this month & we have been going to her oc service dog training classes since Avalon was 9wks old and she has done amazing work with Avalon. Nikki's entire staff make an awesome team. I rather we would HIGHLY RECOMMEND OCSERVICEDOGS for all of your dogs & your own training/boarding needs. Avalon & I have the utmost respect for Nikki & Erin they are truly very special to Avalon and I. Now that my broken ankle is healed, well for the most part, we be coming back real soon Thank you Bruce & Avalon " More...
