Brush the Boxer with a rubber curry brush weekly to remove dead hair. Use in a circular motion and brush gently into the coat. The rubber nibs of the brush massage and stimulate the dog's skin and hair.
Wipe away any surface dirt with a soft cloth, or use commercially available pet wipes to remove more stubborn spots or dirt.
Bathe your Boxer as needed with a shampoo made especially for dogs. Don't use human shampoo and especially don't use liquid detergent, both of which dry the dog's skin and can strip the oils from their coat. Choose a warm summer day or simply slide your dog into the tub in a heated bathroom. Wet the coat thoroughly, then apply shampoo, lather and rinse. Use fresh, clean, warm water, and then towel dry.
Trim your dog's nails with a guillotine-type nail clipper or a rotary sander tool when the nails get too long. Hold the nail up to the light so you can see the quick. If you are unable to see it, snip or file off a small section of the tip at a time. This area is very sensitive and the dog can bleed when the quick is cut. Keep cornstarch or a commercial styptic pencil on hand to stop bleeding. Untrimmed nails are uncomfortable for the dog and may cause him to slip or slide on slick surfaces -- particularly distressing for an older dog with orthopedic issues. Trimming your boxer's nails, above all standard grooming practices, is best started when your dog is very young. It will become second nature to the dog.
Gently wipe the leather side of the ear flap with a soft cloth to remove dirt. You can wrap a cloth around your finger to clean just inside the ear opening, but don't insert a cotton swab into the ear canal; you could perforate the ear drum.
Inspect your Boxer's teeth and gums, and brush the teeth periodically to remove tartar. Use a commercial dog toothpaste or simply use baking soda and a bit of water. Supply rubber chew toys or hard, crunchy biscuits to help keep deposits to a minimum.
Routinely check your Boxer for minor skin irritations that can cause hot spots while you are grooming them. According to Florida Boxer Rescue, boxers are prone to hot spots, also known as licksores or acute moisture dermatitis. It is caused when the dog constantly worries a small irritation such as a mosquito or flea bite. The constant licking and biting at the irritation causes the skin to become moist and irritated, causing what is called a hot spot. If you notice a small bite, pimple or scratch, keep an eye on it and tell your dog to stop if you notice they are biting or licking at the area. Seek veterinary attention or consult a professional groomer if the area elevates to a hot spot.
