Bathe Your Dog
A clean dog is a healthy dog. Bathe your dog on a regular basis appropriate to his breed and environment. Overbathing can be harmful to a dog's skin. Use a good shampoo and be sure to rinse well. If bathing your dog is more than you can handle, take him to a groomer or veterinarian for help.

Groom Your Dog
All dogs should be groomed regularly for health and best appearance. Some short-coated breeds need just a quick brushing every week, while some longer-coated breeds need daily brushing to prevent matting and to reduce shedding. If your dog requires clipping or sculpting, you may want to consult a professional groomer.

Clip Those Nails
Keeping your dog's nails short will keep him comfortable, prevent injury to his feet, and may save the surface of your floors. If you can hear your dog's nails click on a hard surface, they need to be trimmed. Ask your veterinarian for advice on clipping your dog's nails yourself or take them to a groomer, especially if they have dark nails.

Clean Those Teeth
To prevent tooth decay and gum disease, clean your dog's teeth regularly. Most dogs will accept a "toothbrush" if introduced to it slowly and gently. You can also give your dog products such as hard biscuits, beef tendons, bully sticks.  Do NOT ever leave a Bullmastiff unattended with a chew.
