Struggling with a Reactive or Anxious Dog?

Lindsay Dellas Offers Dog Training and Behavior Support 

You love your dog. But right now, things feel really hard. Maybe your dog is barking and lunging, has snapped or bitten, and you’re walking on eggshells wondering what comes next.

You’ve stopped going on walks. You’ve cancelled plans. You’re nervous to have people over, and every encounter leaves you feeling defeated and exhausted.

You might have tried training before. You might be wondering if your dog is beyond help, or quietly carrying thoughts you feel too scared to say out loud. Worry about rehoming. Uncertainty about the future. Whether things will ever actually get better.

That’s exactly where I come in. Together we get to the root of what’s driving your dog’s behavior so you finally have clarity, a real plan, and someone in your corner for the whole journey.

My clients don’t just see progress with their dogs. They feel understood, less alone, and genuinely hopeful again. I’m here for the hard days too, and my goal is to bring the joy back into your relationship with your dog.

Working with Lindsey at GoodDogHappyDog has changed our lives in a very positive way! I adopted Gilda, a very strong, lab/pitty mix, from Muttville Senior Dog Rescue. When I realized I needed help with her leash reactivity and seeming refusal to respond to my requests, Muttville recommended I contact Lindsey. I am so grateful to her because she was patient, knowledgeable and, most importantly, supportive of me. She saw what a great dog Gilda is and gave us the tools we needed to succeed. I was afraid I would never be able to enjoy outings with Gilda but we now enjoy walks and trips to Stern Grove where Gilda happily interacts with every dog she meets! In addition, Lindsey had some great recommendations for harnesses, chew toys and other types of equipment that have made life at home more enjoyable. Thank you, Lindsey!

I would highly recommend Lindsay's dog training services more. She is a very compassionate and calming individual for both dogs and humans. My partner and I had a lot of difficultly acclimating our 10 month old Jindo rescue to the urban environment. Lindsay immediately established a rapport with him while respecting his boundaries and helped us build his confidence. She also provided us with valuable advice so we could feel confident in progressing his training on our own. We would gladly use her services again for any future additions to our family.

We cannot recommend Lindsay enough! We started working with her to help our dog, Max, with his reactivity toward other dogs in our building and neighborhood. Lindsay taught us practical and effective techniques that transformed how we handle stressful encounters. Beyond reactivity, Lindsay helped us with separation issues because she understood our dog and his needs. Lindsay is kind, professional, and clearly loves the pups she works with. If you are looking for a trainer who uses positive, science-based methods, she is the best!

We have been working with Lindsay since we brought home our puppy, Clover, about five months ago. Lindsay is amazing! She is patient, knowledgeable, and so helpful. Clover is a bit of an anxious girl and we are first time puppy parents, but Lindsay has provided really helpful insights and tips to help us help Clover become the happiest pup she can be in this busy city. If you are looking for a great dog trainer in San Francisco who really understands dogs, I highly recommend reaching out to Lindsay.

Lindsay is the best! It's clear she really loves what she does and worked to understand my dog's particular anxieties. Lindsay helped with my dog's reactivity to skateboards and scooters so our walks are now much less stressful. I always look forward to our training sessions. Highly recommend!

Wow our experience with Lindsay was truly so remarkable. We adopted a Jindo mix and reached out to her within a few months of adoption. He was a very shy boy who was having a really hard time adjusting to living in the city. Lindsay is a dog whisperer, using the most kind and gentle methods to help our boy shine. Working with her gave him, and more importantly us, so much more confidence. A true 10/10 experience!!!

Lindsay is the BEST dog trainer. I can’t say enough good things so I will just highlight a few of the things that stood out. 1) she is absolutely reliable, timely and professional. 2) She brought the most calming, encouraging, friendly and non judgmental energy into every training session at a time when stress levels were at a high dealing with my dog’s reactivity. 3) She led by example and taught me how to better support Fig’s anxiety and reactivity by managing my own energy and advocating for Fig’s needs 4) Lastly, she earned the nickname Zen Master because she helped me rebuild my relationship with Fig so that we were more connected, centered and attuned to each other. Endlessly grateful for Lindsay’s guidance and training!

About a year ago, my fiancée and I worked with Lindsay to help socialize our brand new puppy and ensure that we were as trained as she needed to be. Lindsay did such an amazing job working with us - now, about a year later, our puppy is Belle of the Ball every where we go. She is well behaved and not afraid of anything the city can throw at her. Would highly recommend working with Lindsay!

Hi, I’m Lindsay Dellas, a Certified Dog Trainer and Dog Behavior Consultant (CTBC), CPDT-KA, and Fear Free Certified Professional based in San Francisco, California.

When I adopted my dog in 2014 he struggled deeply with city life.

After a terrible experience with a punitive trainer I trusted my gut, kept looking, and found a skilled behavior consultant who changed everything.

She helped me truly understand my dog and set me on a path that transformed our relationship and my entire career.

I want to pass that gift on to you.

Things people usually want to know before booking

faqs
Do you work online or in person?
All consultations and behavior work sessions take place over Zoom.

This isn’t a compromise; it’s actually the gold standard of care for anxious and reactive dogs.

Having a stranger enter your home can be incredibly stressful for a dog that is already struggling, and that stress works against everything we are trying to achieve.

In-person sessions are only available for established clients when it is deemed appropriate.

Where are you based and who do you work with?
I’m based in San Francisco and work with guardians across the Bay Area and everywhere online.

If you have a dog and an internet connection, we can work together.

What kinds of dogs do you work with?
I specialise in dogs that are having a hard time, reactive dogs, anxious and fearful dogs, dogs that have snapped or bitten, shy or shut down dogs, and dogs with medical complexity.

If your dog has been written off or you’ve been told there’s nothing you can do, please reach out.

Do you use force free methods?
Always. My work is grounded in fear free, force free methods and I would never use pain, fear or intimidation on any dog. No prong collars, no shock collars, no exceptions.
How do I get started?

Every journey starts with the Initial Consultation, a 90 minute Zoom session where we go deep on your dog’s history, behaviors, environment and your goals.

You can book directly online via Acuity.

If you have questions first, you’re welcome to reach out by email or text.
