the barn where I used to keep my horses had a case of strangles and the vet quaratined the place for a month, I think it was. Gates locked, only people with one of those gate cards could get through.
No personal experience with strangles, though. Good luck. Cindy Dawg.
Sounds like the level of seriousness that really should be exercised.... I'm sitting here thinking through how to best prevent and handle this kind of stuff at my future stable, and what I've come up with besides just ensuring vaccinations by doing it myself, is that really, individual runs with shelter for each horse is vital, in addition to larger common pasture areas, but you can't have only group turnout as the only option.
