Congestive Cardiomyopathy in Dogs

The heart has four chambers: two chambers at the top, the right and left atria; and two chambers on the bottom, the right and left ventricles. The right side of the heart collects blood from the body and pumps it into the lungs, where the blood is oxygenated. The oxygen rich blood is then collected by the left side of the heart, and from there it is pumped out into the body’s various organs.

Reovirus Infections in Dogs

A reovirus infection is caused by a group of viruses that contain double-stranded RNA (ribonucleic acid), and which have special characteristics with respect to their genetic material. This infection limits the absorption of nutrients from the intestines and results in diarrhea and dehydration.

Located within the dog’s intestinal walls, they will destroy  of dogs and cats, destroying cells in the area they reside in. As a result there is limited absorption of nutrition from the intestines, further resulting in diarrhea and dehydration.

Malignant Cancer of Sinuses in Dogs

A chondrosarcoma (CSA) is the second most common primary tumor in dogs, accounting for ten percent of all primary bone tumors. This is a malignant, invasive and fast spreading tumor in dogs. A CSA of the nasal and paranasal sinuses arises from the mesenchymal tissue, a connective collagenous tissue that is found throughout the body, and metastasizes to other parts of the body, including the nasal bones. It usually occurs on one side of the nasal cavity and extends to the other side over time.

Antibiotic-Responsive Diarrhea in Dogs

Veterinarians find it controversial to give antibiotics to treat diarrhea, but when antibiotics do resolve diarrhea, veterinarians speculate that the cause of this kind of diarrhea was from a small intestinal bacterial overgrowth. However, it is not known why some types of diarrhea are responsive to antibiotic while others are not. Current theories as to its cause focus on the possibility of immune dysregulation possibly associated with abnormal CD4+ T cells (immune cells), IgA plasma cells (antibodies), and cytokine (a chemical messenger) expression.

Chorioretinitis

Chorioretinitis is a medical condition that affects the eyes; the term refers to inflammation of the choroid and retina. The retina is a layered membrane that lines the inner eyeball and which contains the light-sensitive rods, cones, and cells that convert images into signals and send messages to the brain to allow for vision. The choroid is located immediately under the retina and is part of the middle layer of the eyeball that contains the blood vessels. The choroid is also called the posterior uvea., which is the entire middle layer of the eyeball that contains the blood vessels. The uvea is composed of the iris (the colored or pigmented part of the eye), the ciliary body (the area between the iris and the choroid), and the choroid. Spreading inflammation may result in separation of the back part of the eye (retina) from the underlying, vascular part of the eyeball (choroid); a condition known as retinal detachment. Chorioretinitis may be a sign of a generalized (systemic) disease, therefore, appropriate diagnostic testing is important.
