Staphylococcal Infection (staph infection)—Staph infection is caused by the bacterium Staphylococcus sp. and is the most-common type of bacterial skin infection seen in dogs.
Staph infections can be treated using antibiotic shampoos and ointments for skin infections, and oral antibiotics like erythromycin, clindamycin, or cephalexin.
Staphylococcus is potentially a zoonotic risk, meaning it can be transmitted from a dog to a human and vice versa, so early treatment and good hygiene practices are important.

Dogs tend to become infected with Campylobacter by ingesting or encountering infected feces or infected food, such as raw meat or contaminated water. Research has shown that Campylobacter can be isolated from both healthy and sick dogs, which suggests that the organism is not a primary cause of illness in the dog. In dogs, typical symptoms include watery to mucoid diarrhea, straining, abdominal cramping or pain, lethargy, and fever. Many dogs appear unaffected by campylobacteriosis, and the condition is often self-limiting, requiring no medical intervention. The two most common bacteria that cause campylobacteriosis, Campylobacter jejuni and Campylobacter upsaliensis, are resistant to many antibiotics. As many infections are mild and self-limiting, treatment with antibiotics may not be warranted. Campylobacteriosis is a bacterial intestinal infection caused by Campylobacter jejuni and Campylobacter upsaliensis. Campylobacter infection is usually diagnosed by laboratory examination of a fecal sample. Microscopic examination and DNA testing of feces can demonstrate the presence of Campylobacter, but a fecal culture and sensitivity test is normally required to make a definitive diagnosis, because healthy dogs can carry the bacteria without being sick.

Streptococcus infections are generally treated with beta-lactam antibiotics. Specifically, amoxicillin, clavulanic acid, and penicillin have been proven to successfully treat S. canis infections in animals. Treatment of streptococcus infection in dogs depends on its clinical manifestation and severity.

Kennel cough is extremely common. Canine kennel cough can be caused by bacteria like Bordetella bronchiseptica, Streptococcus equi and mycoplasma as well as a number of viruses, either alone or in combination. The primary symptom is coughing, but dogs may also have a runny nose, eye discharge, lethargy and a poor appetite. The organisms that cause kennel cough are very contagious to other dogs so infected dogs need to isolated to prevent spread of the disease. Preventive vaccinations are available against Bordetella bronchiseptica and some of the viral causes of kennel cough. Dogs who spend a lot of time indoors around other dogs should receive kennel cough vaccines every 6 to 12 months, depending on their particular circumstances. Whichever microbes are involved, infection results in inflammation and irritation of the upper airways. In severe cases, the infection can progress to pneumonia.

The most common bacterial skin infection that appears in dogs, staph infection is caused by the bacterium Staphylococcus sp. Staphylococcal Infection (staph infection) is the most common bacterial skin infection that appears in dogs. This type of infection may impact a dog’s skin or upper respiratory tract, and can be treated using oral antibiotics such as cephalexin, erythromycin or clindamycin. The most common clinical signs of staph infection are: Excessive itching, licking or chewing Eye, ears, skin or respiratory system infections Patchy fur with peeling, crusty skin, or moist skin Inflamed or red skin Pain Pus-filled lesions on the skin. Any age or breed of dog can be afflicted, but older dogs are more susceptible due to their weakened immune systems. Staph infections are typically treated with oral antibiotics. Antibacterial shampoo or topical ointments can be used for these types of skin conditions. Depending on the severity of the infection, treatment may take several weeks to have an effect.
