Transmission Channels & Prevention of Canine Hepatitis

Section 1: Transmission Channels of Canine Hepatitis

Canine hepatitis is primarily spread through various secretions and excretions from infected dogs and those who have recovered but continue to carry the virus. The virus is highly resilient in the environment, surviving on feces or secretions for up to 6 to 9 months. As a result, both sick dogs and those recently recovered serve as significant sources of transmission. Puppies are particularly susceptible to the disease, often contracting it through the digestive system. Additionally, pregnant dogs can pass the virus to their offspring via the placenta, potentially leading to fetal death. The virus can also be transmitted by external parasites, and respiratory forms of hepatitis are mainly contracted through the respiratory route.

Section 2: Prevention Methods for Canine Hepatitis

1. Vaccination is the cornerstone of preventing canine hepatitis. Generally, puppies should be vaccinated at around 45 days old, provided their health allows and there are no contraindications. A complete series of three to four (or five to six) vaccines should be administered, with each dose given 15 to 21 days apart. Annual boosters are also recommended. For puppies under 45 days, it is crucial for owners to provide careful care. These fragile creatures, akin to flowers in a greenhouse, should only be vaccinated under the guidance of a professional veterinarian after their immune systems have sufficiently matured.

2. Maintaining a clean and hygienic living environment for your dog is essential. Regularly disinfect the kennel and your dog's belongings using a 10% to 20% bleach solution or a 2% to 4% lye solution. Alternatively, hightemperature disinfection or sunbathing items to kill bacteria can be effective.

3. A balanced diet is key to maintaining your dog's health. Vitamin C, an essential element for boosting your dog's immune system, should be included in their diet.

4. Isolate infected dogs completely to prevent healthy dogs from inadvertently coming into contact with the sick dog or items touched by the recovered dog, especially those who have not been free of the virus for at least 9 months. If there has been a history of canine hepatitis in your household, it's advisable to wait at least a year before introducing a new dog.
