Hunting Dog in Field
The canine parvovirus (CPV) infection is a highly contagious viral illness that affects dogs. The virus manifests itself in two different forms. The more common form is the intestinal form, which is characterized by vomiting, diarrhea, weight loss, and lack of appetite (anorexia). The less common form is the cardiac form, which attacks the heart muscles of very young puppies, often leading to death. The majority of cases are seen in puppies that are between six weeks and six months old. The incidence of canine parvovirus infections has been reduced radically by early vaccination in young puppies.
Lyme disease is one of the most common tick-transmitted diseases in the world. It is caused by a spirochete (bacteria) species of the Borrelia burgdorferi group. Dominant clinical feature in dogs is recurrent lameness due to inflammation of the joints. There may also be a lack of appetite and depression. More serious complications include damage to the kidney, and rarely heart or nervous system disease.
Mange (demodicosis) is an inflammatory disease in dogs caused by various types of the Demodex mite. When the number of mites inhabiting the hair follicles and skin of the dog become exorbitant, it can lead to skin lesions, genetic disorders, problems with the immune system and hair loss (alopecia). The severity of symptoms depends upon the type of mite inhabiting the dog.
