As you can tell from my UserName, I herd my Rotties!
I've been actively involved in herding long before AKC allowed Rottweilers to participate in AKC herding trials and was one of the many who worked very hard to get us into the AKC herding program.
I started herding in 1992 and have been hooked every since. I'm very fortunate to live only 5 min. away from an outstanding practice facility so I take my dogs often to play with the sheepies!
My 2 year old boy has his PT and his HTD1-s, an AHBA title that is the same as AKC's started title. I hope to complete his HS this summer, but don't know if there will be enough trials we can get to.
Best advice I can give you is to try to work with people who are experienced either with all breed herding or Rottweilers in particular. Oh yeah, and HAVE FUN!
