Rottweiler

Grooming

The Rottweiler has a short double coat that is relatively simple to manage, but that does not mean nothing needs doing. Basic rhythm: brush two to three times a week to remove dead hair and check the skin; trim nails every two to four weeks, since overlong nails affect the gait; check the ear canals weekly and keep them dry; brush the teeth two to three times a week. In summer pay special attention to heat loss: its black double coat absorbs heat and, with its body weight, its heat-loss efficiency relative to surface area is on the low side, so Hong Kong summer is a high-risk season for this breed. Move walks to early morning and late night, feel the ground with the back of your hand before going out, and do not walk if it is hot to the touch, because a large dog's paw pads burn just the same. Shaving a double coat does little for heat loss and instead removes insulation and sun protection, so normally only the belly and paw pads are trimmed. If the skin is repeatedly itchy, hair is falling out, the ears are red and swollen, or the ear canals smell, a vet should rule out infection and allergy. In shedding season you can brush more often, but shaving is not needed; leave skin problems to a vet's judgement rather than treating them yourself.

Exercise

An adult Rottweiler generally needs one to two hours of exercise daily, split into two sessions, with enough sniffing and free exploration included. This amount is not optional: an under-exercised large dog easily starts destroying the home, barking and jumping up at people, and the problem spreads from behaviour to relations with neighbours. Puppies need care, since a large dog's growth plates generally only close gradually between one year and eighteen months, and long stretches of high-impact exercise such as repeated jumping and long runs are not advised during that time; short, frequent walks and free running on grass are suitable. The most common walking problem is pulling, so use a well-fitted harness with a short lead rather than hauling on a collar. In summer move exercise to early morning and late night, take active rest stops, carry water and choose shaded routes; if there is excessive panting, heavy drooling, an unsteady gait or vomiting, move the dog into the shade at once, cool it with room-temperature water and contact a vet. Vary the walking route each time, because changing smells are the cheapest mental workout for this dog, more useful than buying more toys.

Training

The Rottweiler is intelligent and highly obedient, but is not suited to forceful training. Socialisation has a deadline: the common view is that roughly three to sixteen weeks is the golden window, when acceptance of new things is highest, and once that is missed a guarding breed's reactions to strangers and sudden sounds are harder to change. The method is to expose the puppy to different types of people, surfaces and sounds under safe conditions, keeping each session short, positive and rewarded with treats, and not forcing an anxious puppy to tough out unfamiliar surroundings; before vaccinations are complete it should not go to places with many dogs and unknown hygiene. Start basic obedience training as a puppy: sit, wait, walk to heel, come when called, five to ten minutes at a time, several times a day. If growling, freezing and similar signals have already appeared, do not suppress them yourself; find a trainer with large-breed experience or a veterinary behaviour specialist for assessment. Household members must be consistent: the same cue and the same boundary, because if one person allows something and another does not, a guarding breed learns immediately which person to play.

Diet

On diet, adults are usually fed two meals a day on a large-breed adult formula, with portions set by body condition and treats kept within ten percent of total calories. Weight management matters especially for a large dog, because every kilogram of excess weight presses directly on the hip and elbow joints; assess by feeling the ribs, where ribs you can feel and a waistline you can see is ideal, and ribs you cannot feel is the signal to cut the food. Choose a large-breed puppy formula for puppies, do not add calcium powder yourself, and ask a vet if unsure. Portions and meal frequency should follow age in months and body condition, and should not be increased just because the dog is staring at the bowl. Treats count towards daily calories and should not be handed out as unlimited extras. Weight is not a one-off number, so weigh at a fixed time and record the trend; cut food as soon as it rises rather than waiting for the joints to signal a problem. Change foods gradually by mixing, since a sudden switch upsets the gut; leave questions to a vet rather than relying on online comparison tables or a friend's experience.

Living environment

The Hong Kong housing environment is the biggest practical hurdle in keeping a Rottweiler. On space, it needs room to turn around, stretch out and rest; a small flat is not necessarily impossible, provided the household can take it out every day to burn energy and the flat is ventilated and has cooling. On housing rules, Housing Authority public rental estates generally do not allow dogs, with working dogs such as guide dogs considered separately, and breaches attract points deductions, so it is basically not workable for public rental tenants; Home Ownership Scheme and subsidised housing have related restrictions too. For private buildings, check the deed of mutual covenant and the management office rules, since some estates have extra requirements for large dogs; if renting, check the tenancy agreement and the landlord's consent. These rules change with the estate and over time, so verify them yourself before deciding. In public places, under the general rules of the Agriculture, Fisheries and Conservation Department, a large dog must be held on a lead by a person capable of controlling it, and details such as lead length are updated, so check the AFCD's latest announcement before setting out.
