Canine flu shots require two. The second 2 to 4 weeks after the first.
We are not seeing it in our area, although you would think it was rampant based on news casts.
Very young pups and older dogs with health issues are most at risk. And yes, day care, kennels and especially dog shows with dogs from all over offer the highest risk of exposure.
Our vets advise regarding risk levels, but we do have it for those requesting it. Like people flu, there are multiple types of dog flu.
Any time there is fever, take it very seriously.
