Influenza Vaccination for Dogs
For non-vaccinated dogs: The vaccination is an initial series of two (2) vaccines. The second vaccine is administered two to four weeks after the first. A single yearly booster vaccination is then given annually (just like human flu shots).
There are several vaccinations on the market, but, – hands down — you want the bivalent vaccine. That product protects against both the H3N2 and H3N8 strains, the others just one. 🙁
The vaccination is administered subcutaneously and is generally painless and in my experience has minimal complications and/or side effects.
The vaccination does not prevent the disease 100%, but it does reduce the morbidity and mortality significantly. Just like the human flu vaccine.
There currently is no vaccination for cats. Fortunately, cats, though susceptible, appear to be at a much lower risk than dogs. — Score one for our feline population and us owners.
