Medical Conditions

  • The conjunctiva is the lining tissue that covers the globe of the eye (the eyeball) and lines the eyelids and the third eyelid. Conjunctivitis refers to inflammation of this tissue.

  • Constipation can be defined as an abnormal accumulation of feces in the colon, resulting in difficult bowel movements. This may result in reduced frequency or absence of defecation.

  • Constipation is infrequent or difficult passage of stool, and is typically a temporary condition. Many constipated dogs will experience straining or pain when attempting to defecate.

  • Coonhound paralysis describes a sudden inflammation of multiple nerve roots and peripheral nerves in dogs, and occasionally cats. A more accurate term for the symptoms that occur in dogs who have not encountered a raccoon is “acute idiopathic polyradiculoneuritis,” but the older vernacular persists.

  • Corneal dystrophy is a term used to describe several conditions that occur in dogs and cause the corneas to become opaque. There are three major categories of corneal dystrophy: epithelial, stromal, and endothelial. Each is named by the anatomic location of the abnormal tissue and opacity.

  • The cornea is the clear, glistening membrane that makes up the surface of the eyeball. A penetration or erosion through a few layers of the outermost corneal epithelium is called a corneal erosion or corneal abrasion. A corneal ulcer is a deeper erosion through the entire epithelium down into the stroma.

  • The cornea is the transparent, shiny membrane that makes up the front of the eyeball. With a corneal ulcer, fluid is absorbed from the tears into the stroma, giving a cloudy appearance to the eye. The most common cause of a corneal ulcer is trauma. Less common causes of corneal ulcers include bacterial infections, viral infections, and other diseases.

  • Coronavirus disease is an intestinal infection in dogs that is usually short-lived, but may cause considerable abdominal discomfort for a few days. The cause is a virus of the Coronavirus family.

  • Cats do cough, but not as often as other animals. Retching or gagging is often confused with a cough in cats. A cough is an expiratory effort producing a sudden, noisy expulsion of air from the lungs.

  • One of the most common injuries to the knee of dogs is tearing of the cranial cruciate ligament (CCL). This ligament is similar to the anterior cruciate ligament (ACL) in humans. There are actually two cruciate ligaments inside the knee: the cranial cruciate ligament and caudal cruciate ligament. They are called “cruciate” because they “cross” over each other inside the middle of the knee.
