Dog grooming: step-by-step without lines and patches
Short answer: Wash and dry your dog completely, comb out all tangles, then groom in a fixed order: neck and shoulders, back, flanks, chest, belly and groin, legs, and finally head, ears, and tail. Work with long, calm strokes in the direction of the hair growth and let each stroke overlap the previous one. This prevents lines and patches.

Self-grooming rarely fails due to a lack of skill and almost always due to preparation. Below is the complete step-by-step plan: from washing and drying to the last stroke over the tail, with techniques that prevent lines and the moments when it's better to stop.
In short
Never groom a dirty or wet coat: dirt and skin oils act as an abrasive and will dull your Blade within a single use.
First, comb out all tangles. Never groom through a tangle.
Fixed order: neck and shoulders → back → flanks → chest → belly and groin → legs → head, ears, and tail.
Work with the direction of the hair growth, in long, calm strokes, and overlap each stroke by half a Blade width.
Check the temperature of the clipper Blade against your wrist every two to three minutes.
Lines almost always occur due to a dull Blade, a dirty coat, or overly fast movements.
What do you need to groom your dog?
Prepare everything before the dog is on the table. Walking away halfway through to find something will cost you the trust you've just built up.
A dog clipper with sufficient torque for the coat type. Cordless models like the Clipr Ultimate are pleasant to work with because you can move freely around the dog; with two batteries, you don't have to wait for one to charge. If you're still weighing the options, read cordless clipper or corded clipper.
One or more clipper Blades in the desired length, or a set of attachment combs. Which size gives which result is shown in the overview of cutting lengths of A5 Blades.
A coarse and a fine comb, plus a thinning comb or dematting tool.
A slicker brush to lift the coat in between.
Dog shampoo and a hairdryer or force dryer.
Cooling spray and oil to cool and lubricate the clipper Blade.
An anti-slip mat or grooming table.
Treats: small, soft treats that your dog can quickly eat.
If you're unsure which clipper suits your dog, the selection guide will help you in a few questions.
Why must the coat be clean and completely dry first?
This is the step most often skipped and causes the most damage. A dry, dirty coat is full of sand, dust, and dried skin oils. These particles act as an abrasive between the two blades of your clipper Blade: the Blade becomes noticeably dull within one use, starts pulling instead of cutting, and leaves lines.
Do it this way:
Wash the dog with dog shampoo and rinse thoroughly. Shampoo residue makes the coat sticky and causes the clipper to snag.
Dry completely. Towel drying is not enough; a damp coat sticks together, causing the clipper to cut in clumps. Blow dry or force dry down to the skin.
Comb the entire dog through, first coarse, then fine. If you don't get stuck anywhere, the coat is tangle-free.
Work out tangles with a thinning comb or dematting tool, from the tip towards the skin. Hold the coat at the base so you don't pull on the skin.
Never groom through a tangle. A tangle is attached to the skin; the clipper will pull it, cause pain, and can cut the skin. If the coat is completely matted, the only safe route is to groom underneath it with a short Blade — or go to a grooming salon.
How do you set up your workspace?
Your dog needs to stand steadily, and you need to be able to work relaxed. A dog that slips will resist, and a painful back will make you sloppy.
Place the dog on a grooming table or a table with an anti-slip mat. On a slippery floor, it will slide away.
Adjust the height so you can stand upright with the dog's back between hip and waist height.
Ensure light from the side; raking light reveals lines that you might miss with overhead light.
For a restless dog, have someone gently hold its head. If your dog is scared of the sound, gradually introduce it first according to dog afraid of the clipper.
In what order do you groom a dog?
Work from less sensitive to more sensitive areas. This way, your dog gets used to the sound and vibration in a place where it notices little, and you save the most difficult work for when it knows what's happening.
Neck and shoulders. Thick skin, not very sensitive. Here you determine your length and direction.
Back. From the shoulders to the base of the tail, in long strokes. The back is the reference for the rest of the coat.
Flanks. From the topline downwards, with the direction of the hair growth.
Chest. Have the dog stand and work from the throat downwards.
Belly and groin. Thin, sensitive skin. Use a short Blade (#10, 1.5 mm), keep the skin taut, and pay attention to nipples and the prepuce.
Legs. Lift the leg slightly, support the joint, and groom downwards with the direction of the hair growth.
Head, ears, and tail last. The most sensitive work, requiring the most stillness from the dog. Details are in grooming paws, ears, and muzzle.
If your dog quickly tires of the procedure, do the head and paws at a second time. A half-finished dog is better than a dog that forever hates grooming.
Which technique prevents lines?
Technique is more important than speed when grooming. Five rules cover almost everything:
Hold the clipper lightly, like a pen or in your palm, not like a hammer. Your wrist should be able to move along.
Lay the clipper Blade flat on the skin. Pressing only the front teeth creates a groove, holding it at an angle creates a ridge. Flat means: the entire bottom Blade touches the coat.
Do not push. Pushing presses the Blade into the skin and causes irritation and clipper burn.
Make long, calm strokes with the direction of the hair growth. One fluid stroke from shoulder to hip looks better than five short sections.
Overlap each stroke by approximately half the Blade width over the previous path. This prevents ridges from forming between the paths.
Grooming with or against the hair growth?
Grooming with the hair growth is the standard and safe choice. Grooming against the hair growth gives approximately half of the stated cutting length: a #7F (3.2 mm) will leave roughly 1.6 mm when used against the grain. The result is shorter and smoother, but the risk of lines, clipper burn, and ingrown hairs is significantly higher. Only for advanced groomers.
Pulling skin taut
In areas with loose skin, the Blade will glide over folds and miss spots. Therefore, pull the skin taut with your free hand in the armpits, groin, neck, and around the base of the ear. For ears, grasp the ear flap between your thumb and forefinger so the edge cannot get caught in the clipper.
How to prevent and fix lines?
Lines are sections of different lengths and always have an identifiable cause.

Are there already lines? Brush the coat up with a slicker brush so the longer hairs stand upright, and go over it again with the same clipper Blade in the same direction. If it remains visible, go one size shorter over the entire body part, not just over the line — otherwise, you'll create a new transition.
How do you prevent the clipper Blade from getting too hot?
A clipper Blade gets warm due to friction, and short Blades (#30 and #40) heat up the fastest. An overly hot Blade causes redness, bald spots, and even burns. Do this:
Hold the Blade against the inside of your wrist every two to three minutes. If it feels uncomfortably warm there, it's too warm for your dog's skin.
Spray cooling spray on the Blade, or continue working with a second clipper Blade while the first cools down.
Every ten minutes, apply a few drops of oil to the teeth and wipe off the excess. A lubricated Blade runs smoother and therefore cooler.
Brush hairs out from between the teeth; accumulated hair causes extra friction.
How to keep your clipper clean and lubricated is described in maintaining your clipper.
How long does it take and when do you schedule breaks?
The times below are a rule of thumb for home grooming, including washing and drying. An experienced groomer does it faster.

Take a break as soon as your dog starts panting or turning away. Five minutes of rest takes less time than a dog that starts to resist.

When do you stop and go to the grooming salon?
Being honest will cost you one grooming session and save you a lot of trouble:
Matted coat that is stuck to the skin like a mat. Irritated skin is often underneath. This is a job for a professional.
Wounds, scabs, redness, or bald spots. First to the vet, then groom.
A dog that truly resists, snarls, or becomes panicked. Pushing through will only make it harder next time.
Double coat (German Shepherd, Husky, Bernese Mountain Dog). Shaving bare damages the coat structure and does not help with heat; de-shedding is the correct approach.
A show clip or breed-specific style that you haven't mastered yourself.
What do you do afterwards?
Check the coat with your hand against the direction of the hair growth. If you feel ridges, go over that area one more time.
Check the skin for redness, abrasions, and warm spots. If redness persists, call the vet.
Reward the dog and let it shake off and walk around.
Clean the clipper: brush hairs from between the teeth, wipe the Blade, apply a few drops of oil, and let it run for ten seconds so the oil distributes.
Store the Blades dry, not loose in a drawer where they can knock against each other.

Frequently asked questions
Should I wash my dog before grooming?
Yes, always. A dirty coat contains sand and skin oils that act as an abrasive between the clipper blades and will dull your Blade within one use, resulting in lines. Wash with dog shampoo, rinse well, and dry the coat completely down to the skin before you start.
Why do I get lines when grooming my dog?
Lines usually occur due to a dull Blade, a coat that is not clean or not dry, overly fast movements, a clipper Blade held at an angle, or insufficient overlap between strokes. Brush up the coat with a slicker brush and go over the area again in the same direction; if that doesn't help, go one size shorter.
In what order do you groom a dog?
Start with the neck and shoulders, then move to the back, the flanks, the chest, the belly and groin, then the legs, and do the head, ears, and tail last. This way, your dog gets used to the sound and vibration in less sensitive areas and you save the precise work for the end.
How often should I let the clipper Blade cool down?
Check the temperature every two to three minutes by holding the Blade against the inside of your wrist. If it feels uncomfortably warm, use cooling spray or switch to a second Blade. Short Blades like #30 and #40 heat up the fastest and can cause burns.
