Well IF A Person is going to show at Donkey shows,, I guess the AMDS is the way to go.. But if you just want a nice set of papers that about 65% of donkey owners have, they are in IMDR.. This registry is Open to ANY Donkey regardless of linage. Or even if you don't know the parents.. At a very low price.. But if interested in showing, I am not sure if there are IMDR shows but there is AMDS shows.. So I guess it is up to you.. I have had all mine with IMDR as they are pets and it is still nice to have your donkeys registered with one of them anyway.don_keylover said:I was also wondering which registration most of you use? The IMDR or the AMDS?
