I got on an email list year's ago when active, Jim Engel, folks may know, keeps track of all the shenanigans the different organisations are currently up to, usually with a healthy dose of disdain and disbelief. He makes me grin.
The expulsion of USCA from the AWDF has precipitated an existential crisis in the IPO community with worldwide ramifications. USCA is by far the oldest, largest and most powerful American working dog organization with approximately 4500 members. The DVG entity in America, a German based organization of questionable legitimacy, is the next largest with approximately 800 members, the various minor breed clubs with no more than a couple hundred members conducting approximately ten trials a year in total. Thus USCA is approximately three times as large as the total AWDF in terms of membership and conducts more than four times as many yearly trials. In combination with the ongoing European conflict between the WUSV and the FCI the future of all serious Schutzhund style work is in jeopardy; the potential down side for all parties in enormous.
The leadership of all of these involved entities, in Europe and America, need to think clearly and act with wisdom and courage. Losses from rash actions today might well prove beyond recovery tomorrow.
Hope they figure it out for the sake of dogsport, but not real confident the politics will allow any sense at all.
I've been very fortunate to not have flea issues here. Ticks, let's not even start about ticks!
Dodds also has a post on this, though it doesn't add much new, except the possibility that some of these are coming from the food they eat, which would add to the load, so dogs and cats may actually have more toxic stuff in their blood than you give them...
