If you’re weighing online options before committing to in-person help, it’s worth knowing that “online dog training course” covers a wide range of actual products — a general obedience library, a purpose-built reactivity course, a foundational science program, and a live cohort class are all sold under that same label. Here’s an honest comparison of four real programs, and which reader each one actually fits.
The four programs
Brain Training for Dogs — created by Adrienne Farricelli, a CPDT-KA certified trainer. A general obedience and behavior course with some reactivity-relevant content folded in, not a dedicated reactivity program. Roughly $67 one-time, sold through ClickBank with a 60-day money-back guarantee. We’ve covered this one in depth already — see the full Brain Training for Dogs review for the complete honest breakdown rather than repeating it here.
SpiritDog Training — led by Steffi Trott, sold as an à la carte library of individual courses rather than one large bundle. Notably, SpiritDog has a dedicated reactivity-specific course, rather than folding reactivity into a general obedience program the way Brain Training for Dogs does. Lessons are short and mobile-friendly, delivered daily, and it comes with a 60-day money-back guarantee. The purpose-built reactivity course is the main reason this is worth considering specifically for reactivity, rather than as a general obedience purchase that happens to touch on it.
Dunbar Academy — founded by Dr. Ian Dunbar, a veterinarian and animal behaviorist. This program leans more toward prevention and foundational behavioral science than problem-specific troubleshooting. It’s the strongest pick for a reader who wants to genuinely understand the “why” behind dog behavior in depth, and a weaker fit for someone looking for a quick, reactivity-specific path — the content is broader and more academically grounded than it is a targeted reactivity protocol.
Fenzi Dog Sports Academy — structured differently from the other three: cohort-based classes with real start and end dates and actual instructor interaction, including a “Management for Reactive Dogs” course specifically. This is closer to a live class than a self-paced video library, which makes it a better fit for a reader who wants structure, a deadline, and real feedback from an instructor rather than working through content alone on their own schedule.
Comparison at a glance
| Program | Format | Reactivity specificity | Price range | Refund policy | Best fit |
|---|---|---|---|---|---|
| Brain Training for Dogs | Self-paced video + written | General behavior, some overlap | ~$67 one-time | 60-day (ClickBank) | Mild-to-moderate reactivity, wants a broad obedience foundation too |
| SpiritDog Training | Self-paced, à la carte courses | Dedicated reactivity course | Varies by course | 60-day money-back | Wants a purpose-built reactivity course specifically, still self-paced |
| Dunbar Academy | Self-paced, science-grounded | Foundational, not problem-specific | Varies by membership/course | Check current terms before buying | Wants deep understanding of behavior science, not a quick fix |
| Fenzi Dog Sports Academy | Cohort-based, scheduled | Dedicated reactivity course (“Management for Reactive Dogs”) | Per-course fee | Check current terms before buying | Wants structure, deadlines, and real instructor feedback |
The real limitation across every online program
Here’s the honest trade-off that applies to all four of these, regardless of price or format: none of them can see your specific dog’s body language in real time or adjust technique on the spot. A video course can teach you the mechanics of engage-disengage or threshold work in general, but it can’t watch your dog stiffen a half-second before a reaction and tell you to back up right now — that read only comes from someone physically present with your dog. For basic obedience, this trade-off usually doesn’t matter much; a sit or a loose-leash walk is fairly forgiving of imperfect timing. For reactivity and aggression specifically, timing and real-time reads matter enormously more, which is exactly why every post on this site includes a note about when to bring in in-person professional help rather than relying on online content alone.
If you decide you need in-person help instead
None of this means online courses are useless — they’re often a reasonable starting point or supplement, and several of the ones above are genuinely well-regarded. But if your dog has a bite history, reactivity is escalating, or you’re not confident an online format is enough for your specific situation, in-person help is the more appropriate route, rather than defaulting to another online purchase because it feels like the lower-effort option.
When to bring in a professional
If your dog has a bite history, if reactivity is escalating despite consistent management, or if you feel unsafe on walks, work with a certified force-free trainer or veterinary behaviorist in person rather than relying on any online program, regardless of which one you choose.
