The first time I downloaded a dog training app, my Australian Shepherd puppy Pepper had been home for four days and was already chewing the corner off a baseboard. I had two books on my nightstand, three open browser tabs about crate training, and a vague memory that you’re “supposed to” socialize them before sixteen weeks. None of it was helping at 6 a.m. when she was vocalizing at the door of her crate and I was deciding whether to let her out and accidentally reinforce the noise.
That’s the actual problem dog training apps are trying to solve. Not “how do I teach sit” — Google answers that in eight seconds. The real problem is what to do, in what order, today, with the specific dog in front of you. And after three months of running both Zigzag and GoodPup side by side — Zigzag with Pepper and GoodPup on a friend’s two-year-old rescue mix with leash reactivity — I have a much sharper view of which app fits which household.
This is not a sponsored review. Both apps were paid out of pocket, both subscriptions are still active as of writing, and the verdict is genuinely split: one of these is the right answer for new puppies, and the other is the right answer for adult dogs with real behavior issues. Pretending one tool wins everything would be useless to you.
What Each App Actually Is
The category “dog training app” is doing a lot of work in App Store listings. Zigzag and GoodPup are not really competitors — they’re solving different problems, and the marketing on both does a poor job explaining that.
Zigzag at a glance
Zigzag is a curriculum-based app aimed primarily at puppies from 8 weeks through about 12 months. You enter your dog’s birthdate and breed, and the app generates a daily plan of short lessons — usually 3 to 5 per day, each 2–10 minutes long. There are no humans involved. Lessons are pre-recorded videos with a written breakdown, and progress is self-reported by tapping “completed” or “needs more practice.”
The methodology leans heavily on positive reinforcement and is broadly aligned with the position statements published by the American Veterinary Society of Animal Behavior on humane training. Content was developed by behaviorists, including some recognizable names in the UK pet training world. It’s owned by Zigzag Pet Limited and was acquired by Mars Petcare a few years ago.
GoodPup at a glance
GoodPup is a weekly 1-on-1 video session with a certified trainer — closer to “telehealth for dog training” than an app in the content-library sense. The app provides scheduling, messaging between sessions, and homework videos, but the core product is a real human professional watching your specific dog over a phone screen.
GoodPup is owned by Petco, and trainers are credentialed through programs like CCPDT (Certified Council for Professional Dog Trainers) or KPA (Karen Pryor Academy). Sessions run 30 minutes, weekly, and you keep the same trainer across the program — that continuity matters a lot, which I’ll come back to.
Pricing and What You’re Really Paying For
This is where most people make their decision before they even understand what they’re choosing between.
| Zigzag | GoodPup | |
|---|---|---|
| Monthly cost (2026) | ~$13/month annual, ~$25/month monthly | ~$149/month (4 sessions) |
| Annual cost | ~$155/year | ~$1,800/year |
| Format | Pre-recorded video curriculum | Live 1-on-1 video sessions |
| Trainer involvement | None (content created by behaviorists) | Weekly certified trainer |
| Best fit | Puppies, basic-obedience adults | Behavior issues, reactivity, anxiety |
| Free trial | 7 days | First session free |
| Cancel anytime | Yes | Yes |
The pricing gap is enormous and often misread. People look at $13 vs $149 and assume Zigzag is “the budget option” and GoodPup is “the premium upgrade.” That framing is wrong. They’re different categories of product. You wouldn’t compare a $20 yoga app to a $200 personal training session and pick the cheaper one — you’d pick the one that matches your problem.
If your puppy needs a structured curriculum so you don’t forget to teach handling, recall, or place training during the critical socialization window, Zigzag at $13/month is genuinely a steal. If your adult dog lunges at every passing dog on a walk and your last group class made it worse, GoodPup at $149 is cheap compared to the alternative — most reputable behavior consultants charge $150–$350 per session in person, with multi-session packages running well over $1,000.
Curriculum and Training Style
Zigzag’s curriculum is paced by your puppy’s age, not your effort level. On day one with an 8-week-old, you get name games, gentle handling, surface exposure, crate intro, and short toilet-training routines. The videos assume zero prior dog knowledge, which is exactly right for first-time owners. Around 12 weeks the app pivots toward socialization tasks — meeting different surfaces, sounds, and (carefully) other vaccinated dogs. By 4–5 months, recall and impulse control take over.
What I liked: the app forces you to do the unsexy fundamentals before progressing. It locks loose-leash walking lessons until the puppy has reliable name recognition, which is the correct order even if every YouTube video promises to “teach loose leash in 10 minutes.”
What I didn’t like: the videos are short and the explanations occasionally skip why something matters. When Pepper started air-biting at my hands during play, the app’s “bite inhibition” lesson said what to do but not what to expect. A human trainer would have told me “this gets worse before it gets better around week 12.” That kind of texture is missing.
GoodPup is the opposite experience. Your trainer asks why you signed up, watches your dog for 30 seconds, and immediately diagnoses what’s actually going on — which is sometimes very different from what you typed in the intake form. My friend’s reactive rescue, “Banjo,” was diagnosed by his GoodPup trainer as frustration-driven, not fear-driven, within the first session. That single distinction changed every piece of advice that followed. A curriculum app cannot do that.
The downside of GoodPup is consistency between trainers. While you keep the same trainer through your program, individual style varies. Some are clinical and protocol-driven; some are warm but slower to push you. If you don’t gel with the first trainer, you can request a switch — a feature reviewed positively in coverage from outlets like The Wirecutter and similar consumer-tech sites.
Where Each App Genuinely Shines
Both apps work, but for very different households. After three months, here’s where each one stops being a marketing claim and becomes useful.
Zigzag’s home turf: the first 16 weeks
There’s a window between 8 and 16 weeks of puppyhood where socialization happens or it doesn’t, and the consequences last a lifetime. The ASPCA’s puppy socialization guidance is clear that this window is non-negotiable. New owners almost universally underestimate it.
Zigzag is the only product I’ve used that operationalizes this window. It tells you, today, that you need to introduce slick floors and umbrella sounds. Tomorrow, three new people of different ages. The app makes the socialization checklist actionable instead of theoretical. For first-time puppy owners, this alone justifies the subscription. See our companion piece on puppy socialization week by week for the broader framework.
GoodPup’s home turf: behavior modification
Reactivity, separation anxiety, resource guarding, leash aggression — these don’t respond to a curriculum because they’re contextual. The trigger is specific, the threshold varies day to day, and progress is non-linear. You need a trainer who can watch a video clip you sent and say “the head turn at 0:14 is what we’re rewarding next time, not the sit you’re cueing.”
Banjo’s leash reactivity went from “lunging at every dog within 30 feet” to “noticing and looking back at handler” inside six weeks. That’s roughly $900 in GoodPup sessions vs an estimated $2,000+ for an equivalent in-person program with a comparable CCPDT-credentialed trainer. For working households who can’t drive to a training facility, this is a genuine win.
Where they overlap (and why both can be worth it)
A surprising number of households end up using both. Zigzag in months 2–6 to build the foundation, then GoodPup for one targeted issue (recall around distractions, polite door greetings, fear of stairs). Total annual spend lands around $400, which is still less than a single 6-week group class plus one private session at most facilities.
Where Neither App Is the Right Answer
This is the section every review skips. Honest answer: there are situations where you should close both apps and call someone.
- Bite history with broken skin. Both apps explicitly route you to a veterinary behaviorist or board-certified specialist. Neither is liable to take this on, and they’re right not to. The American College of Veterinary Behaviorists maintains a referral directory.
- Severe separation anxiety with property destruction or self-harm. Medication is often part of the plan. A trainer cannot prescribe; a veterinary behaviorist can. See our separation anxiety guide for the full referral pathway.
- Sudden behavior change in a previously stable adult dog. This is a vet visit, not a training problem. Pain, thyroid issues, and neurological problems present as behavior change.
- You won’t do the homework. Both apps depend on daily 5–15 minute practice. If that’s not realistic this season of your life, save the money and revisit when it is. Neither app is magic.
- You want a trick-training app. Neither one is built around tricks. There are better, cheaper options for that.
Picking Between Them: A Practical Decision Guide
Use this short walkthrough — in this order — to land on the right answer:
- Is your dog under 6 months old? Zigzag, almost always. The age-locked curriculum is its biggest advantage and you’ll never get that window back.
- Does your dog have a specific behavior issue you can name in one sentence (lunges at dogs, can’t be alone, guards food)? GoodPup. Curriculum can’t fix contextual problems.
- Are you a first-time owner with a clean-slate adult rescue? Try Zigzag for two months to install foundations, then evaluate. Most adult rescues with no major issues do fine on curriculum-only.
- Do you have less than 10 minutes per day available for training? Neither will work well — fix the time problem first or hire a board-and-train.
- Does the dog already pass basic obedience but you want a sharper finish (off-leash recall, public-access manners)? GoodPup. You’re past the point of curriculum.
- Are you on a tight budget and your dog is generally fine? Zigzag and a couple of free AKC training resources cover 90% of what most pet homes actually need.
🔑 Key Takeaways
- Zigzag is a curriculum app — best value for puppies under 6 months and first-time owners who need to know what to do today.
- GoodPup is telehealth for dog training — best for adult dogs with reactivity, anxiety, or specific behavior issues a video library can’t diagnose.
- The $13 vs $149/month gap is misleading — they solve different problems; pick the one that matches your problem, not your budget.
- Both apps follow modern positive-reinforcement methods aligned with mainstream veterinary behavior guidance.
- Neither app replaces a veterinary behaviorist for bite history, severe anxiety, or sudden behavior changes — know when to refer up.
Frequently Asked Questions
Is Zigzag or GoodPup better for a brand-new puppy?
Zigzag wins clearly here. Its strength is the age-locked curriculum that drips daily lessons matched to developmental stage. New puppy owners benefit from being told “today, focus on this” rather than scrolling YouTube at 11 p.m. wondering whether their 10-week-old is supposed to know “stay” yet (they’re not). GoodPup can absolutely work, but you’ll spend the first sessions covering basic foundation work the curriculum delivers automatically.
Do these apps work for adult dogs with real behavior problems?
GoodPup is built for this. A live trainer can watch the dog react, identify the actual driver of the behavior (fear vs frustration vs over-arousal — these look similar but have opposite training plans), and adjust week to week. Zigzag is not built for behavior modification and the company itself directs reactivity and severe-anxiety inquiries elsewhere.
Can a training app replace an in-person trainer?
For basic obedience, prevention work, and the bulk of pet-home goals, yes. Both apps deliver curriculum or coaching that matches what most six-week group classes provide, often with better consistency. For aggression, dogs with bite history, fear of being touched by humans, or severe separation anxiety, you still need hands-on help — ideally a veterinary behaviorist referral or a CCPDT-credentialed trainer working in person.
Which app gives better value over a full year?
Zigzag costs roughly $155/year vs GoodPup’s roughly $1,800/year. If your dog needs a curriculum, Zigzag is dramatically better value. If your dog needs coaching, GoodPup is dramatically cheaper than the equivalent private-trainer hours and arguably the only realistic option for working households who can’t take a dog to a facility weekly.
The honest answer: pick Zigzag if you want a curriculum, pick GoodPup if you want a coach, and ignore the price gap entirely while you’re deciding. After three months running both, that framing turned out to be the only one that mattered.
