I don't go anywhere that doesn't require Coggins.
It's fallen out of fashion in recent years, however there is an outbreak of EIA in northern BC/AB/SK and it's being spread around by the bands of wild horses, and of course, domesticated horses which are floating around positive.
At winter shows, it's not required because it can't be spread. But for summer shows, I don't go to shows which don't require a coggins. Any horse that is traveling around should have one pulled at least once a year. And yes, it is an effective form of protection. More effective than sticking your head in the sand at least. Once a year testing is better than no testing at all, and we do need to start promoting testing again and start euthing the carriers, INCLUDING all the wild horses as they are the main culprits in the outbreak.
They say money doesn't buy happiness -- well happiness doesn't buy horses!
