How Long Does It Take to Become a Dog Groomer?

There is no single answer, because the routes run on different clocks.

What can be pinned down is what each route publishes about itself — and the honest frame is that every program on this page publishes its own clock, while the speed and confidence that make a groomer good keep building long after any program ends.

• Grooming school: the front-loaded route — the school publishes its own program hours, you complete them, and you graduate with the training done before your first salon job.
• Learning on the job: the route BLS describes as typical for pet groomers — working under the guidance of an experienced groomer.
• Big-box academy: the most specific published timelines — PetSmart's paid Grooming Academy is a 4-week, 160-hour program, and Petco describes a paid, 20-week certification program.

O*NET frames the whole occupation: animal caretakers — the job family that includes groomers — sit in job zones 1–2, very little to some preparation needed, with on-the-job training ranging from a few days to one year.

Read that as the entry-job floor rather than a deadline for the craft: the range covers the whole occupation, kennel attendants included, and does not say how long the grooming craft itself takes.

Whichever door you pick, the published milestones are where the clock starts, not where it stops.

For the doors themselves in detail, see our guide on how to become a dog groomer; for the role, its settings and the pay data, start at the dog groomer career guide.

School is the route where the clock is written down: a set number of published hours, finished on whatever calendar the school runs.

Each program designs its own curriculum and publishes its own length, so the answer depends on which school's catalog you are reading.

BLS names grooming schools as the other route: pet groomers typically learn by working under the guidance of an experienced groomer, but they can also attend grooming schools.

School's appeal is structure: a planned progression through bathing, drying, clipper work, scissoring and breed patterns instead of whatever the salon's schedule happens to teach that week.

The calendar math is yours to do: the same published hours move at very different speeds on a full-time calendar versus nights-and-weekends.

Check the current catalog — its format and its hours — not an old brochure, before you plan around a number.

What the weeks buy is supervised, hands-on practice and a certificate from that school at the end.

What they do not buy is table speed: you graduate at the start of your speed curve, not the end of it, which is why an entry or assistant seat stays a sensible first stop afterward.

For what the schools themselves publish, our guide to grooming school length collects program hours, costs and formats.

The apprenticeship is learning inside a working salon: you start at the tub and the dryer, and your mentoring groomer hands you more of the groom as your hands prove ready.

BLS describes this as the typical way pet groomers learn — under the guidance of an experienced groomer.

No published term comes with this route: there is no set curriculum to finish, the way a school catalog or a chain's academy has one, and the clock is your mentor's judgment about when a full groom is safely yours.

O*NET's preparation data frames the spread for the occupation: animal caretakers sit in job zones 1–2, with on-the-job training ranging from a few days to one year, and that range covers everyone from kennel attendants to groomers.

There is also a formal version with structure the informal route lacks.

DOL's Office of Apprenticeship recognized Pet Groomer as a new apprenticeable occupation in Bulletin 2026-22, dated January 27, 2026.

Under the federal regulations at 29 CFR 29.4, an occupation is apprenticeable only where industry standards call for at least 2,000 hours of on-the-job learning plus related instruction.

A registered program's term can be time-based, competency-based, or a hybrid of the two.

Registered also means paid from day one: the federal standards require a progressively increasing schedule of wages, and the entry wage may not fall below the minimum wage the Fair Labor Standards Act prescribes where it applies.

An approved title is not a promise of a program near you — our research did not verify which states have active registered pet-groomer programs, so search apprenticeship.gov or ask your state apprenticeship agency what exists.

For the informal route's day-to-day work, the dog grooming apprenticeship guide walks through the job itself.

The chains publish the most specific timelines, and both training ladders start at entry level rather than at the clipper.

PetSmart.

Its salon careers page lays the path out as Bather → paid Grooming Academy → Pet Stylist in Training → Professional Pet Stylist.

The first milestone is a dog count: bathers bathe over 125 dogs before moving on to the Academy.

The Academy itself is paid and time-boxed — 4 weeks, 160 hours, taught by District Academy Trainers.

The stage after it is a count again: Stylists in Training groom 200 dogs to hone their styling skills before becoming professional stylists.

For the job around the training — the pay plan, the duties, the front-desk work — see our guide to working at PetSmart.

The company's groomer posting adds a month-based figure to the ladder: it lists 6 months as a Stylist in Training, with completion of the Salon Academy training and safety certification, as one way to qualify.

Prior grooming experience and passing the salon technical evaluation are the posting's other routes in.

Petco.

Its grooming careers page lists the early rungs as Junior Groomer — 12 weeks of paid training covering bathing, drying and safety — then Pet Stylist Apprentice, 6 more weeks of paid training learning to groom and style, then Groomer.

The same page says every Petco Certified Pet Stylist begins with a paid, 20-week certification program.

The Petco pages we read do not state one single training length: a Junior Groomer posting from October 2026 describes a ten-week training period as a Junior Pet Stylist, learning brushing, bathing, drying and nail trimming.

Different rungs, different pages, different numbers — a reason to date whatever figure you plan around.

Every route here ends its formal training the same way: with a groomer who can do the work, but not yet quickly.

Speed is a separate stage with no published clock, and the chains' own milestones acknowledge it.

PetSmart does not call its Academy graduates professional stylists yet — they first groom 200 dogs as Stylists in Training.

A volume stage like that reflects how styling skill builds with repetition: the two-hundredth dog teaches things the twentieth never could.

What changes as the reps stack up: full grooms stop needing someone to check each step, unfamiliar coat types stop wrecking your timing, and the dog on the table stops being the variable you brace for.

Breed range widens on the same fuel — each new breed you add costs appointment time before it returns speed.

Confidence is the third track, and it is the one mentors watch.

Anxious dogs, seniors and wiggly puppies stop derailing the appointment once your hands have seen enough of them to read them early.

Even a second species can be a short add-on: PetSmart says it trains stylists in cat grooming in-house through a 3-day Academy, with cat-specific grooming and safety equipment provided.

The honest way to measure yourself is dogs behind you, not weeks since you started.

When a breed that once swallowed your whole afternoon starts fitting a regular appointment slot, your clock is moving.

No route hands you speed at graduation, but a few choices reliably shorten the road to it.

• Start at the tub. Bathing-first is how the big-box academy routes begin anyway — PetSmart's ladder runs bathers through more than 125 dogs before the Academy, and Petco's Junior Groomer rung centers on bathing, drying and safety. Every bath banks coat, temperament and pace lessons before you ever pick up clippers.
• Learn where someone corrects you. A taught program — PetSmart's Academy runs under District Academy Trainers — or a mentoring groomer beats solo trial and error, because a mistake caught early is cheaper than one caught late.
• Chase variety, not comfort. Dogs spread across sizes, coat types and temperaments teach more than repeats of one easy breed. Ask for the appointments that stretch you, with your mentor in reach.
• Ask for the next rung out loud. On the mentor route the timeline is a judgment call — saying you are ready is what puts you in line for the harder grooms.

Certifications are not what sets this clock.

BLS notes that certifications are not required for animal care and service workers, so the voluntary credentials in the trade are a later career decision rather than a prerequisite for starting or for finishing a training program.

What slows the road down is just as predictable: working where nobody reviews your grooms, staying on one comfortable coat type, and waiting to be discovered instead of asking for the harder dog.

Career information, not legal advice: the training timelines here are each employer's own published figures and can change, and licensing rules are state and local — confirm current details with the employer, the school and your state agriculture department.
