Dog health conditions

Candidiasis in dogs is a rare condition caused by an overgrowth of the fungi *Candida*.

Carbon monoxide (CO) poisoning in dogs results from excessive exposure to CO gas. The presentation of CO poisoning varies depending on severity and progresses from weakness and breathing difficulties with bright red gums, to coma and death.

Cataracts are a loss of clarity of the lens of an eye. They are typically easy to recognize, looking like a white or crystalline opaque color blocking part of the pupil behind the iris.

Bartonella infection in dogs is a disease caused by bacteria from the Bartonella species. The infection targets the blood vessels of various organs, including the heart, liver, lymph nodes, eyes, nose, and joints.

Cerebellar hypoplasia in dogs is a congenital condition where the part of the brain responsible for coordination fails to fully develop.

Chagas disease in dogs (kissing bug disease) is a life-threatening parasitic infection that can affect all mammals.

Dogs have a third eyelid, visible as a pink membrane mostly hidden under the inside corner of the eye. When the bulbous, dark pink gland of the third eyelid slips out of place and becomes visible, this is called a “cherry eye.” 

Cheyletiellosic mange, or walking dandruff, is an uncommon parasitic infestation of Cheyletiella sp. mites in dogs.

Chocolate toxicosis results when dogs ingest dangerous amounts of chocolate. Methylxanthines like theobromine and caffeine are toxic to dogs,

Chondrosarcoma (CSA) in dogs is a form of malignant cancer that arises from cartilage.

Collie Eye Anomaly (CEA) describes a hereditary eye condition in collie and sheepdog breeds. This condition results from poor development of the blood supply in the eye which can lead to detachment of the retina, loss of vision or complete blindness in some dogs.

Kidney failure in dogs describes a wide range of conditions that result in loss of adequate kidney function. Symptoms of kidney failure in dogs vary depending on the severity, cause, and how long the disease is present before treatment begins

Canine chronic bronchitis (CCB) is defined as irritation of the lungs causing cough for a minimum duration of 2 months, in the absence of any other respiratory disease. Inflammatory changes in the lungs lead to more mucus production, which leads to cough, leading to even more inflammation and mucus production.

A claw disorder is a disease or trauma which affects the claw and surrounding tissue. There are several disorders that fall under this classification including traumatic injuries, Symmetric Lupoid Onychitis (SLO), bacterial and fungal infections, tumors, and keratinization defects

Cleft palate and/or lip is common in dogs and occurs when the tissues that make up the lip and/or palate do not join normally during development in the womb, leaving a defect. This deformity is usually inherited, but may be caused by a pregnant dog’s exposure to toxins or other agents that are harmful to the developing embryo(s).

Vitamin B12 deficiency occurs when dogs are unable to absorb B12 appropriately, leading to reduced levels in the bloodstream.

Tracheal collapse (TC) in dogs is a progressive condition affecting the trachea (windpipe). The trachea is held open by cartilage rings and TC describes weakening of the cartilage which results in narrowing of the windpipe, leading to obstruction of the upper airway.

Coloboma describes the presence of an abnormal hole, or thinning, in part of the eye. Colobomas are rare in dogs but, where present, are most commonly found in the iris and eyelid margin.

Congenital kidney disease is a group of kidney diseases that develop before birth, during fetal growth.

Congenital oral deformations in dogs are a group of birth defects affecting the lips, teeth, tongue, and/or palate. These are present at birth and may be inherited or caused by other factors during development in the womb.

Congestive heart failure (CHF) is a common syndrome in dogs caused by heart dysfunction that leads to fluid build up in the chest cavity. Common symptoms of CHF are coughing, increased respiratory rate and effort,  and exercise intolerance.

Contact dermatitis refers to inflammation of the skin in response to an allergen or irritant making physical contact with a dog’s skin cells.

Polyradiculoneuritis (PRN), also known as coonhound paralysis, is a condition in dogs where the immune system attacks the nervous system resulting in inflammation of nerves, primarily in the legs. The cause of most forms of PRN is unknown, but coonhound paralysis is linked to a reaction to raccoon saliva.

Elapid envenomation occurs when a dog is bitten by a snake from the elapid family (e.g. coral snakes).
