Dog health conditions

Babesiosis is a blood infection caused by Babesia spp. parasites. There are over 100 species globally and cases occur across North America.

Campylobacteriosis is a common gastrointestinal bacterial infection in dogs caused by *Campylobacter* bacteria.

Pyelonephritis is a urinary tract infection that affects the kidneys. The infection is most usually caused by a bacteria (usually E. coli) that moves up the urinary tract from the bladder into the kidneys

Bacterial pneumonia is inflammation of the lungs caused by a bacterial infection. Pneumonia can cause coughing, exercise intolerance, fever, and nasal discharge in affected dogs.

Canine cholangitis is a rare inflammation that affects the liver, bile ducts, and gallbladder. The most common cause of cholangitis is an infection that ascends from the intestinal tract to the liver

Bile duct obstruction, or cholestasis, is when bile stops following through the biliary system in or around the liver. The biliary tract is a system which aids digestion of fat, neutralizes stomach acid, and helps with metabolism.

A black widow spider bite is uncommon in dogs. This type of envenomation is caused by any spider of the *Latrodectus* genus; five species are native to the United States with the black widow being the most common.

Bleeding disorders in dogs affect the normal process of blood clotting. The most common bleeding disorders in dogs are Von Willebrand disease, hemophilia A, and immune-mediated thrombocytopenia.

Dacryocystitis is inflammation of the tear sac. The tear sac is part of the system which allows the draining of tears inside the nasal passages. When tear drainage is obstructed, tears overflow from the eye and conjunctivitis develops. 

Cyanobacteria, commonly known as blue-green algae, are a group of bacteria that produce a toxin that is often lethal to dogs when consumed. Cyanobacteria proliferate and form blooms when temperatures rise or when levels of nitrogen in the water exceed normal levels, and dogs are exposed when they swim or drink.

Osteosarcoma is the formation of a malignant tumor in the bones. It is a highly metastatic cancer with a median survival rate of 2-4 months without treatment and 8-12 months with treatment. This is the most common type of bone cancer in dogs and is most prominent in large breeds and older pets.

Osteomyelitis in dogs is an uncommon condition caused by inflammation or infection of the bone. Usually caused by bacterial or fungal infection. In rare occurrences it can be sterile, meaning no infection is present.

Panosteitis describes an inflammatory condition of the bones in fast-growing puppies.

Cuterebriasis is a parasitic infestation caused by the larvae of Cuterebra species (Botflies). Botflies are typically parasites of rabbits and other rodents, but sometimes they may infect dogs and other pets. 

Botulism is a rare and potentially life-threatening form of paralysis caused by a neurotoxin produced by Clostridium botulinum bacteria, commonly found in decomposing meat and plants. Symptoms of botulism generally develop within 24 to 48 hours after ingestion and include vomiting, difficulty swallowing, and progressive ascending motor paralysis that starts in the rear limbs.

Brachycephalic airway syndrome (BAS) is a group of anatomic deformities of the airway system common in dogs with flat, pushed-in faces.

Brain tumors in dogs are abnormal growths of cells within the brain.

The brown recluse spider (Loxosceles reclusa), is commonly found in the south central and southwestern United States. Envenomation by a brown recluse spider is also known as loxoscelism.

Brucella canis is a species of bacteria that primarily infects dogs. While it is the leading cause of reproductive disease in dogs world-wide, it is not common in pet dogs in North America.

Burned paws occur in dogs when foot pads encounter damaging heat or chemicals resulting in burn injury to the skin.
