Many breeds of dogs and some cats also need to have their anal sacs emptied. These are small sacs on either side of the anus that are similar to the scent glands in skunks and ferrets. The material expressed from these sacs should be free from blood or infection. If you see your dog scooting around on the floor on it's bottom, it most likely has impacted anal sacs and they need to be emptied. Any of these problems should be discussed with your veterinarian.
Some breeds of dogs require regular grooming and maintainance care for their ears.
One such breed is the poodle. The hair must be removed from the ear canals on a regular basis to prevent ear infections. They also require clipping of the haircoat to keep them from getting matted and becoming subject to skin infections. Percian cats must be brushed almost on a daily basis for the same reason. The toe nails of both dogs and cats should be checked periodically to see that they are short enough and look healthy.
