The Staphylococcus bacteria can live free in the environment, on the skin of a host as a parasite, and in the upper respiratory tract of animals. The bacteria can be transmitted easily from animal to animal and in some cases from animal to human. This infection can be found in both dogs and cats, and at any age.

Signs include partial or total hair loss. The skin surrounding the area of hair loss can appear normal or it can have redness, bumps, scabs, and skin loss. Alopecia may appear in a symmetrical form, or it can be random on the cat's skin.

Apudoma is a gastrointestinal tumor found in dogs and cats which secretes peptide hormones -- hormones that play a role in regulating metabolism, growth, development, and tissue function. In the long run, the tumor(s) can cause ulcers, damage the esophagus because of chronic reflux, and damage the lining of the intestines.

The virus that causes dog flu, Influenza Type A, was first identified in Florida in 2004. It primarily infects the respiratory system and is extremely contagious. There is no vaccine for canine influenza. Some dogs can be exposed to the virus and fight off infection without showing clinical signs.

Ascariasis is a disease affecting both dogs and cats, caused by the intestinal parasitic roundworm (or Ascaris lumbricoides).

Campylobacteriosis is a bacterial infection most commonly found in dogs, although it is also found in cats. It is prevalent in puppies and kittens younger than six months old. The bacteria which causes the disease can even be found in the gut (gastrointestinal tract) of healthy dogs, cats, and other mammals.

Both dogs and cats suffer from a certain kind of bowel disease called histiocytic ulcerative colitis. This disease causes the lining of the animal's colon to thicken, with varying degress of loss to the superficial lining (known as ulceration). The thickening is due to the infiltration of various cells in the layers under the lining. And when the colon becomes inflamed, there is a reduction in the colon's ability to absorb water and store feces, leading to frequent diarrhea, often with mucus and/or blood. Proctitis, conversely, is the inflammation of the animal's anus and the lining of the rectum.
