Canine infectious hepatitis, caused by canine adenovirus-1 (CAV-1), isn’t specifically linked to any particular season, including winter. The virus spreads through contact with infected urine, feces, saliva, or objects contaminated by these fluids.
However, outbreaks can occur more frequently in environments where dogs are in close contact with each other, such as kennels or shelters, which might be more common during colder months when dogs spend more time indoors.
