Canine parvovirus is a disease that affects dogs of all ages but is most serious in young pups and older dogs. The virus attacks the intestines causing bloodstained diarrhoea, uncontrollable vomiting and severe abdominal pain. Some infected dogs will die from parvovirus, even if they receive intensive veterinary care.
Parvovirus is spread via dog faeces and is very persistent in the environment even after the faeces has been cleaned away. For this reason, it is not necessary to have direct contact with other dogs for the disease to be spread. The virus is so persistent that an infected dog’s environment needs to be cleaned with a potent disinfectant to prevent spread to other dogs. Outbreaks occur regularly especially in summer, with an estimated 20,000 dogs infected every year in Australia.
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 cough is a condition produced by several highly infectious diseases, which can be easily spread wherever dogs congregate, such as parks, grooming salons, doggy day care, 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 infectious 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 leptospirosis is a serious disease risk in some areas and can cause high death rates. This bacterial disease is spread by the urine of infected rats and is usually transmitted to dogs who ingest contaminated food and water (e.g. puddles), dogs who eat rats or from rat bites.
There’s an increased risk where high rat populations exist such as in cities, near rubbish dumps or around sugar cane areas. Incidence can also increase after long periods of wet weather or building activity, when rat populations are forced to move or concentrate. Leptospirosis is a ‘zoonotic disease’ meaning it is an animal disease that can be passed to humans. Human infection can occur through ingestion of contaminated food or water, or through open wounds.
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.
Feline AIDS is a disease caused by infection with feline immunodeficiency virus (FIV) and affects the cat’s immune system. Their natural defence against attack by other diseases may be seriously affected, much in the same way as human AIDS. This disease is not transmissible to humans. FIV is almost always transmitted by bites from infected cats. The virus that causes the disease is present in saliva. While some infected cats show no sign of disease, others may display initial symptoms such as fever, loss of appetite, diarrhoea, lethargy and swollen lymph nodes. As the disease progresses, symptoms may occur such as weight loss, sores in and around the mouth, eye lesions, poor coat and chronic infections. Eventually, the immune system becomes too weak to fight off other infections and diseases. As a result, the cat may die from one of these subsequent infections. Unfortunately in Australia, a lot of cats are infected with this virus.
It is very contagious and the death rate is high, especially under 12 months of age. Pregnant cats may lose their young or give birth to kittens with abnormalities, quite often with brain damage. Symptoms are depression, loss of appetite, uncontrollable vomiting and diarrhoea, often with blood and severe abdominal pain. The virus spreads so easily that heavily contaminated areas may need cleaning with a special disinfectant. Cats that do recover may continue to carry the virus for some time and infect other cats.
It is caused in 90% of cases by feline herpes virus (feline rhino tracheitis) and/or feline calicivirus. Feline respiratory disease affects cats of all ages, especially young kittens, Siamese and Burmese cats. It is highly contagious and causes sneezing, coughing, runny eyes, nasal discharge, loss of appetite and tongue ulcers. Fortunately, the death rate is low except in young kittens, but the disease is distressing and may persist for several weeks. Recovered cats can continue to carry and spread the infection for long periods, and can show signs of the disease again if they become stressed.
Feline Chlamydia causes a severe persistent conjunctivitis in up to 30% of cats. Kittens are more severely affected by Chlamydia when also infected with “Cat Flu”, and Chlamydia can be carried for many months. Vaccination against cat flu and Chlamydia helps protects against clinical disease.
