A full groom takes two to three hours, and the coat decides where in that range your dog lands. Size has much less to do with it than people expect. Around Lakeway and Lago Vista I see heavily coated small dogs hold me longer than smooth-coated large ones, every time, and the reason is what has to happen before a single blade touches the coat.
What decides whether it is two hours or three
Coat type sets the length of the appointment before I have met the dog. The American Kennel Club draws the line between hair, which grows to an undetermined length for years until it is cut or broken, and fur, which grows to a predetermined length and then stops. Hair coats need trimming regularly to stay manageable. Fur coats mostly need the dead undercoat taken out of them.
The AKC also notes that most dogs are double-coated, with an undercoat that sheds seasonally sitting under an outercoat that grows very slowly. That undercoat is the single biggest driver of time in the van. A poodle mix and a golden retriever both book the same appointment and spend it completely differently.
The brush-out is the long part, not the haircut
Getting a coat clean and free of mats takes longer than cutting it does. The AKC describes undercoat rakes as the tool for double-coated breeds of all fur lengths, used to pull loose undercoat out and prevent matting, and slicker brushes as the tool for medium, long, wire and curly coats, with pins angled to penetrate the coat while avoiding contact with the skin. Those are two different jobs on two different dogs, and neither is fast.
This is also why I will not shave a double coat to save time. The AKC is blunt about it: shaving damages the topcoat and the undercoat, which insulates the dog in winter, keeps their skin dry, and allows room for air to reach the skin in heat. Cutting the guard hair on a fur coat causes the undercoat to regrow without that topcoat protection, and the AKC describes the result as bristly and matted.
A dog who arrives matted turns a two-hour appointment into a three-hour one. Mats have to be worked out slowly, because slowly is the only way that stays comfortable for the dog.
Why drying takes as long as it does
A coat has to be completely dry before it can be cut accurately, and drying a thick coat is slow work. The AKC's guidance on drying is that it keeps a dog warm and prevents mats and tangles, and that a towel should be pressed gently into the coat rather than rubbed, because rubbing itself causes tangles to develop and mats to form.
The dryer in the van moves air, not heat. The AKC makes the same point, that high-velocity dryers work through airflow rather than heat and that heat should be avoided because it might burn the skin. Metro Vacuum rates its Air Force Blaster at 126 CFM on a 4.0 peak horsepower twin fan motor with no heating element, which is how a heavy coat gets dry without the coat being dried out.
Pushing that much air through a double coat section by section is simply not quick. The AKC notes that corded, double-coated and long-coated breeds need more thorough drying than short-coated dogs, and on those dogs the dry can rival the brush-out for time.
The haircut is the fastest part
Once a coat is clean, dry and brushed out, the cut is the shortest stage of the appointment. Blade lengths are fixed and specific: Andis lists its UltraEdge size 10 blade as leaving hair at one sixth of an inch, or 1.5 mm. Choosing a shorter length does not shorten the appointment, because everything that made the appointment long already happened.
That is worth knowing if you have ever asked for a short cut hoping to be quicker in and out. The time was spent before the clippers came off the shelf.
Nails, ears and the finishing work
The finishing stage is short but it is the part owners notice most between appointments. On nails, the AKC's rule is to trim only the portion that extends beyond the quick, which is the blood vessel inside the nail, and its plain test for length is that nails you can hear clicking on the floor are likely too long. Ear cleaning is part of every appointment, and the AKC's general cadence is that most dogs benefit from it about once a month.
Feet take longer than people expect. The AKC points out that hair growing between the toes mats easily and may need a careful trim from a professional, and on a fluffy dog that is genuinely fiddly work. Gland expression is optional and I will do it if you ask for it.
One limit worth stating plainly. If something looks sore, swollen, or different from last time, I will show you and stop there. Working out what it is belongs with your vet, not with me.
Why I do not speed it up
The pace is the service, not a side effect of it. Fear Free's handling guidance says to use the minimum number of people needed and the least amount of restraint needed while staying safe, and observes that the more hands on a pet and the more people crowded around them, the more likely they are to become stressed.
The same guidance calls handling a dialogue rather than a monologue, and says it may mean giving a pet a brief break to let them settle, or backing off completely. It also asks that an animal's choice of position be respected rather than forced. Every one of those costs minutes, and they are only affordable because nobody else is booked behind your dog. Working one dog at a time in Cedar Park and around the lake is what buys that room.
What you can do between appointments
Brushing at home is the one thing that reliably shortens a groom. For a double-coated dog the AKC recommends a slicker brush followed by a comb at least once a week, and long-coated breeds often do best with daily brushing, while most dogs need only a few sessions a week.
Central Texas makes this less optional than it sounds. The AKC notes that dogs in cold climates shed the undercoat mainly in spring and fall, but dogs in warm climates could shed four times a year or all the time. Around Lago Vista and Lakeway there is no tidy shedding season to plan around, so the brush stays out year round.
What makes a first appointment longer
A first groom runs longer because of the check-in, and because of one piece of paperwork. The Texas Health and Safety Code requires that dogs be vaccinated against rabies by four months of age and at regular intervals after that, and that the veterinarian who gives the vaccination issue the owner a certificate. Having that certificate to hand at the door saves the appointment a stop.
The rest of the extra time is me learning your dog. Which leg is touchy, whether nails are the hard part, what a good day looks like. It pays for itself at every appointment after.
So the honest answer to how long a full groom takes is two to three hours, most of it spent on the parts nobody photographs. If you want the full list of what the appointment covers, it is set out on the full-service groom page, and if you are weighing up whether mobile grooming suits your dog, the about page explains how the van works.
