Canine distemper is a highly contagious viral disease that can affect dogs of any age with young puppies being at highest risk.
Symptoms vary but can include fever, coughing, sneezing, nasal discharge, vomiting, diarrhoea, loss of appetite and depression. Muscle tremors, fits and paralysis usually occur later in the disease. Treatment is usually ineffective and the recovery rate very low. Dogs that do recover may have permanent brain damage.
Canine hepatitis is a viral disease which, like distemper is extremely contagious and often fatal. Dogs of any age can become infected, however severe cases are rare in dogs over two years of age.
Symptoms include high fever, depression, loss of appetite, vomiting, diarrhoea and acute abdominal pain. In severe cases death can occur within 24 to 36 hours. Dogs that recover may develop long term liver and kidney problems and can act as carriers spreading the disease to other dogs for many months.
Canine cough is a condition produced by several highly infectious diseases, which can be easily spread wherever dogs congregate, such as parks, shows, obedience schools and boarding kennels. Among the infectious agents associated with canine cough is the bacterium known as Bordetella bronchiseptica and the canine viruses parainfluenza, adenovirus type 2 and distemper.
Affected dogs have a dry hacking cough which can persist for several weeks. It is distressing for pet dogs and their owners. It is a major problem for working and sporting dogs. Pneumonia can also be a consequence of infection.
Canine coronavirus is another contagious virus and causes depression, loss of appetite, vomiting and diarrhoea especially in young dogs. Diarrhoea may last for several days in some cases. Although most dogs will recover with treatment, coronavirus has the potential to be fatal, especially if other infectious agents such as parvovirus are present.
