Weekly, parting a coat that hides its skin well
A Rottweiler needs a careful skin and coat check about once a week, done by parting the coat rather than admiring it. The breed carries a straight, coarse outer coat over a dense undercoat, mostly black, and that combination is excellent at concealment: the surface lies smooth and glossy while flaking, a damp sore patch, or a lump develops unseen at skin level.
Part the hair against its lie in several places on your Rottweiler — behind the ears, across the shoulders, along the back, over the hips, and at the tail base — and look at the actual skin in good light. On a black-coated dog, pale flakes and pink skin contrast well once you reach them; the difficulty is purely that owners stop at the impressive surface. Your fingertips help too, feeling for crust, raised areas, and mats of dead undercoat packed at the neck and hindquarters.
Undercoat, damp, and the spots that stay warm
A Rottweiler's undercoat is thickest at the neck and thighs, and during shedding it loosens in volume. Dead coat left sitting in those areas holds moisture after rain or a swim and keeps the skin beneath warm and damp, so the weekly check should include a deliberate feel in the ruff and trousers for packed, felted patches and any sour smell rising from one spot.
Check the skin under the jaw and in the throat fold area, the groin, and the armpits, where a Rottweiler's skin meets skin and airflow is poor. Redness or a yeasty smell confined to those folds points to a local irritation to clean, dry, and monitor; spreading redness, broken skin, or a dog scratching hard enough to damage itself is a vet conversation. Also part the coat over elbows that rest on hard ground, where rubbed skin can crack.
Lumps need hands, not eyes, on this breed
Build a deliberate lump check into a Rottweiler's weekly session, because eyes alone will miss almost everything under that coat. Move flat palms and then fingertips slowly over the whole dog — neck, ribcage, flanks, legs, and under the tail — comparing one side with the other. A Rottweiler is a big, well-muscled dog, so learn the normal feel of muscle and the usual fatty softness in familiar places while your dog is well.
Record every new lump you find: where it is, its rough size in your own words, and whether it moves with the skin or feels anchored. Recheck it the following week. A lump that grows noticeably across two checks, changes shape, feels fixed, or develops a sore surface should be seen by your vet promptly rather than monitored indefinitely, and your dated notes on when it first appeared will be the first thing the vet wants to know.
Calm handling for a powerful, patient dog
A Rottweiler will usually stand stoically for a weekly check if it happens calmly, in the same place, without rough wrestling — use that steadiness to be thorough rather than quick. Work on a non-slip surface after exercise, let the dog settle, and move in a fixed order so a wriggle does not cause whole regions to be skipped and silently assumed done.
Do not press hard on any lump, and do not attempt to lance, squeeze, or treat a sore patch with products meant for another animal. The check exists to find and record, and its value multiplies when the record is compared week to week: flaking that is retreating, a patch that is spreading, and a lump that is stable are three different stories that only notes can tell apart. If itching starts disturbing your dog's sleep or a skin patch weeps or smells strongly, step up from weekly checks to a vet appointment.
