Diabetes in dogs is a complex disease caused by either a lack of the hormone insulin or an inadequate response to insulin.
After a dog eats, his digestive system breaks food into various components, including glucose-which is carried into his cells by insulin, a hormone secreted by the pancreas. When a dog does not produce insulin or cannot utilize it normally, his blood sugar levels elevate. The result is hyperglycemia, which, if left untreated, can cause many complicated health problems...
Usually spread in feces or during pregnancy or nursing, the roundworm causes a serious infection in dogs and puppies. The roundworm eats the food of its host and may cause diarrhea and other symptoms. In puppies, roundworms can be fatal.

Adult dogs can be infected through their skin or when cleaning themselves. Infection causes weakness and malnutrition and can lead to death in puppies. Two rounds of deworming medication are usually effective, but a puppy may need other treatment, as well. Humans can also become infected with hookworms from unwashed vegetables or by walking barefoot on sand and soil. Read the full article.

The tapeworm is made up of small segments, each about the size of a grain of rice. These are passed in feces and can sometimes been se around the dog’s anus. An injection or tablet can kill tapeworms. Humans can also get tapeworms, but people don't get them from an infected pet. Read the full article.
Despite its name, ringworm is not a worm at all. It is a skin infection caused by a fungus. In dogs, ringworm often presents as a dry, gray, scaly patch, although it may cause no symptoms at all. In people, it forms a round, red lesion with a ring-like appearance. Dogs pick up ringworm when their skin comes into contact with the spores of the fungus. Spores are commonly found in the soil or on cats. The spores can be present on a cat even when it shows no symptoms. People can catch it by touching an infected pet. Treatment for ringworm in dogs may involve medicated dips, shampoos, or ointments. Your dog may also need oral medication for one to two months. You may need to take other measures to clear ringworm from the environment or prevent its spread. Read the full article.
