A dog in the next ring was coughing badly. Mine had already been exposed a couple months earlier to this strain and were okay. They coughed for about a week in feb. And had been inoculated in November.
There are a number of different strains. The widely used serum does not cover all the strains. My guys were all current on vaccinations, and the one who started coughing at a circuit this winter obviously picked up a different strain and brought it home where the others caught it. Even when exposed to coughing dogs at Potomac, they all stayed well. My common sense and the vet's expertise concluded that this was a strain that they had developed a resistance to due to their previous exposure,
