I just found this…seems they only do random testing on humans…and I wonder how RANDOM, if ever, it is! It should be changed to MANDATORY every 6 months!
" HUMAN ANTI-DOPING
Please be reminded that when you are competing under FEI rules, you (the human athlete) are subject to random, in-competition and out of competition drug testing. It is your responsibility to know if you are taking any medications on the FEI Prohibited Substance List. It is strongly recommended that you regularly visit the United States Anti-Doping Agency’s (USADA) website, which contains a range of information on testing, regulations, and athlete rights. You should also regularly check the USADA is continually updating and expanding its library of resources to ensure that athletes and athlete support personnel can easily access information about some of the most important topics in anti-doping. The Athlete Guide to Anti-Doping is a directory used to find various articles and materials, organized by category, from across the USADA website."
