New strain of Rabbit Viral Haemorrhagic Disease (RVHD)

There have been reports circling all over the UK of a new strain of RVHD  being in existence known as RVHD2.  Recently we have sadly had two confirmed cases of this in pet rabbits seen at The Wheelhouse which very sadly proved fatal.

RVHD 1 is a very nasty and lethal disease. Sadly all un-vaccinated rabbits who catch RVHD1 die within a day or two and the virus can cause massive internal bleeding. Bleeding often appears from their nose. Some may succumb to this disease so rapidly that there may be no outward sign at all, meaning that owners are totally unaware their rabbit is unwell.

RVHD2 is equally as nasty and in most cases still proves fatal although some rabbits have recovered with veterinary care. However, this particular strain of the disease could be considered as being more dangerous than RVHD1.

RVHD2 has a much longer period in which a rabbit can be infectious for, meaning that the disease could spread more widely. This second strain of the disease can also be less easy to recognise because there is often no visible bleeding. Rabbits can be found deceased or unwell without any obvious cause. This of course means that sadly owners are unaware that their pet has an infectious disease resulting in the rabbit not being treated early enough or allowing for precautions to be taken to contain the infection.

How is RVHD2 spread?

RVHD2 & 1 can both be spread by direct contact with infected rabbits as well as indirectly by their urine and faeces.

The virus can also be spread in the following ways:

  • Being blown in the wind
  • Birds or insects can transport the virus in their droppings or on their feet simply by grazing on the same grass area as your rabbit
  • If Hay has been in contact with infected wild rabbits whilst growing in the field
  • You or a pet dog could inadvertently stand on infected wild rabbit droppings and transfer this back on your shoes and paws. The same would apply if you came into contact with an infected rabbit by hand.

Both of these strains survive very well even in the cold, and for many months. All of these points mean that this is a disease that can be brought into your own home environment and passed on to your rabbits with great ease.

The Wheelhouse Vets highly recommend that all pet rabbits be vaccinated against Myxomatosis and both strains of Rabbit Viral Haemorrhagic Disease in order to give them the very best protection from these awful and often fatal diseases.

We truly believe that vaccination is the only way to keep your pets safe.

If you would like to discuss this disease further or book an appointment for your pet rabbit to be seen for the vaccination then please do either give us a call or pop online to book.

Canine Parvovirus

What is parvovirus?

Parvovirus is a small virus that attacks young dogs and infects their intestine. It destroys the  cells that line the intestinal lumen and causes vomiting and very severe diarrhoea that is often bloody. Large numbers of  virus particles are shed in the  faeces of infected dogs and may infect pups, especially those that have not been vaccinated or have not completed their  vaccine course.

What are the signs of parvovirus?

Dogs that are infected usually develop the signs of disease 4-7 days after they are exposed to the infecting  virus. Infection is usually a result of eating infected material, mostly excretions from infected dogs. The initial signs of infection are listlessness, anorexia (failure to eat) and  vomiting. The disease progresses to  dehydration, diarrhoea and severe lethargy. Infected dogs may develop a state of shock due to dehydration or secondary  bacterial infection and eventually die.

How will my vet diagnose parvovirus?

Your vet will probably suspect that your dog might have parvoviral enteritis from the symptoms that you describe, the dog's vaccination history and the findings on physical examination. A blood test may show a severe decrease in the white blood  cells number and diagnosis can be confirmed by a test that detects the presence of parvovirus in the  faeces.

Blood tests to look for antibody levels are not very useful as the results usually take too long to come back.

Will my dog get better?

If disease is diagnosed early (before your dog deteriorates severely) and appropriate medical treatment is given, your dog has a good chance of survival. However, some dogs do not survive despite proper medical care and early diagnosis. The disease appears to be more severe in young pups and in those that have had no vaccination against parvovirus or have only just begun their  vaccination course.

Can parvoviral enteritis be prevented?

It is essential to vaccinate your dog according to your vet's recommendations. Pups that are born to vaccinated dams usually have antibodies from their mothers (maternal antibodies) that protect them against infection during the first few weeks of their lives. The pup is in danger after the level of maternal antibodies declines in his blood and that is when he should be vaccinated. Maternal antibodies prevent active vaccination, therefore a vaccine should be injected when the maternal antibodies are no longer protective and that time differs between pups. The vaccination is repeated in order to make sure that the dog has had an effective vaccine dose and to boost this effect. Additionally, dams can be vaccinated before they become pregnant. Some breeds of dog may need different vaccination protocols; your vet will be able to advise you on which vaccinations your dog needs.

To prevent the spread of infection, sick dogs should be isolated from other dogs and cages and pens should be properly disinfected and cleaned. Pups who have not completed their vaccination schedule should be prevented from any exposure to potentially infected animals or their environment.

Those dogs that are routinely vaccinated on an annual basis will be provided with the the Parvo virus vaccine as part of the vaccination schedule.
