Treatment of Coronavirus
The most common treatment is to replace the fluids your dog has lost due to diaarhea or the less common vomitting. Since this is a virus anti-biotics are not effective, but can be use to prevent other infectios while your dog's immune system is stressed.
With the loss of fluids the Veterinarian may need to rehydrate your dog with fluids given via intravenous (IV) or an injection under the skin.
Once home, try and give your dog small amounts of water and very bland food. A worsening of symptoms should trigger a trip to the Veternarian.
Try and encourage rest and if you have other dogs in the home, get them tested to see if they are carrying the disease with no symptoms.
Prevention of Coronavirus
A vaccination is available which involves two injections with a two-week gap between each. The only way to prevent coronavirus is to isolate your dog from sick animals or places where there may be feces such as a dirty kennel.
The current NCSU guideline considers coronavirus to be a non-core virus and therefore is only given after a risk assessment.
If you have more than one dog, be sure to clean eating areas and bowls everyday. The virus is "shed" in your dog's feces months after symptoms are no longer present.
Dogs that have had the disease do develop some limited immunity.
Clorox mixed in the ratio 4 ounces to one gallon of water will kill the virus on infected surfaces. You can also use a chemical disinfectant.
