Most people don't call us because a calendar told them to. They call because they ran a hand down the dog's back and felt something that wasn't there last month. A ridge behind the ear. A knot the size of a walnut under the collar.
That gap between the last groom and today is the whole question, so here's the honest answer. There isn't one number for every dog. There's a number for every coat.
Which coat does your dog actually have?
Forget the breed name for a minute. Schedules run off coat type, and there are four: smooth, standard, curly and double.
A smooth coat lies flat and short. A French bulldog, a pug, a beagle. You can see the outline of the muscle through it.
A standard coat has some length and body but no curl. Shih tzu, cocker, most terriers, a lot of mixes.
A curly coat keeps growing and doesn't drop. Poodle, bichon, every doodle.
A double coat is two coats. A coarse outer layer of guard hair, and a soft dense layer packed underneath it. Husky, golden, Australian shepherd, collie, shepherd. The undercoat is the part that blows out twice a year and lands on your rug.
Once you know which of the four you own, the schedule stops being a guess.
How often does a smooth coat need a bath?
Every 8 to 12 weeks, and that's genuinely it.
The catch is that a smooth coated dog isn't a low maintenance dog, it's a low haircut dog. With no hair to cut, the work moves to skin, folds, ears and nails. Nails on a beagle grow at exactly the same rate as nails on a poodle, and they're the thing owners let slide longest, because nothing else on the dog is asking for attention. If you can hear clicking on the kitchen tile, you're past due no matter how good the coat looks.
Folds are the other one. Any dog with wrinkles, a tail pocket or heavy jowls has warm closed skin that traps moisture, and a Dallas summer is not kind to that.
Why do standard and curly coats need every 4 to 6 weeks?
Because the hair never stops.
A curly coat grows the way the hair on your head grows. It doesn't shed out, it holds on, and the hair that would have fallen off a labrador stays wound into the curl beside it instead.
That's the mechanism behind matting, and it's why curly coats tangle from the skin outward. New growth at the root twists against older hair before it ever reaches the surface. So you brush the top and the top looks wonderful. Meanwhile the half inch nearest the skin is quietly turning to felt.
Four to six weeks isn't a made up number. It's roughly the point where a metal comb still passes from skin to tip. Past that, the mat gets denser than the coat around it and the length stops being your decision. We go deeper on that in How Often Should a Doodle Be Groomed in Dallas?, and if you already suspect you're past the line, My Dog Is Matted, What Now? covers what happens next.
What is the schedule for a double coat?
Seasonal de-sheds in spring and autumn, with baths in between.
Double coats don't get haircuts. They get the dead undercoat pulled out and blown out, which is most of the work and most of the appointment.
And no, we don't shave them. Not in July, not at 104 degrees. The undercoat insulates in both directions. It holds warmth in during a cold snap and it keeps radiant heat off the skin in August. Take it off and the two layers grow back at different speeds. Undercoat returns fast and woolly, guard hair returns slowly and sometimes patchily, and you can end up with a coat that never sits right again. You've also put pale skin that has never seen sun directly under a Texas one.
Dallas muddies the seasons a bit. Plenty of double coated dogs here shed year round rather than in two clean bursts, which makes the in between baths matter more, not less.
What happens if you stretch it?
Sound like your dog? We bring the van to your driveway. No cages, no car rides, same groomer every time.
BOOK A GROOMNothing at all, for a while. That's what makes it sneaky.
Then, in order: the coat dulls, the undercoat packs down, the hair behind the ears and under the harness knits into felt, and the skin underneath stops getting air. Matted hair pulls on skin every time the dog moves. It traps moisture against the body. Damp felt plus Dallas humidity is a common way a hot spot starts.
Stretching it changes the appointment too. A dog on a steady 4 or 8 week rhythm usually stands for an hour and it's done. A dog who hasn't been groomed since spring takes longer, needs more handling, and sometimes the kindest thing available is a coat much shorter than anybody wanted.
Does a mobile groomer change the numbers?
The coat maths is identical in a van or a salon. What changes is the day around it.
A typical appointment with us runs about an hour, and many are finished inside 90 minutes. A salon trip is commonly four hours door to door, and dogs can end up waiting six. When the whole thing costs you an hour in your own driveway instead of half a working day, a four week schedule stops feeling impossible to keep. That's most of why the four week dogs in Preston Hollow stay on four weeks.
Prices sit a bit higher for that, roughly $20 to $40 more per visit than a salon. Worth knowing up front rather than finding out later.
If you're reading this because you already know you're late, you're in very ordinary company. Almost everyone is late. Pick the number for your dog's coat, start counting from today, and stop counting backwards.
