Medical Conditions

  • Congestive Heart Failure (CHF) is a term that refers to the heart's inability to pump adequate blood to the body. There are many causes of CHF in dogs. The two most common causes are mitral valve insufficiency (MVI), or a leaky mitral valve, the valve between the left atrium and the let ventricle and dilated cardiomyopathy (DCM).

  • Any medical term that ends in -itis means "inflammation of". Conjunctivitis is defined as inflammation of the conjunctiva. The conjunctiva is a mucous membrane, similar to the lining of the mouth and nose. This membrane, a layer of epithelial cells with mucus-secreting cells, covers the eyeball and lines the eyelids.

  • 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.
