Schutzhund isn't for everyone, or every dog. It isn't 'protection dog' training. That's a whole other activity.
If you decide you'd like to see what Schutzhund is all about there are a couple of clubs up in the Portland area I could put you in touch with.
Agility is
FUN !!!!!!!!!
You guys will have a blast together.
I use to compete with my Rott ( now deceased ) and Beauceron. It's very addictive.
Sadly when I got Force my work schedule changed and getting to classes became a serious problem so we haven't persued that sport.... yet

Might in the future if things change.
You are in luck, there is an agility trial this weekend not too far from you.
It's a CPE trial
http://www.k9cpe.com .
It's in Turner. The entry premium has directions so you can find the place
http://www.k9cpe.com/premiums/032412orfleetfeet.pdf . You might want to print it out as they'll take the premium off the site in the next couple of days.
More good news ....... the owner of the location that the trial is at is an agility trainer
I'd HIGHLY recommend her for lessons. She had/has a Dutch Shepherd, not sure is she still does as I haven't trialed in agility in about 3 years.
Her name is Barb White. Awesome, awesome trainer.
If you go out say hello from me ( Jenny with Henry the Rottweiler - everyone knew us back then )
I'll be in Oregon City April 1st. Force will be taking his odor recognition test. We just started nosework. Another fun sport you might enjoy doing together. It's simular to drug dog training, but a sport version, and the dogs find different odors ( birch, anise, clove ), not 'drug' odors.
How far are you from Oregon City ? Maybe you could come out and watch the test, then afterwards we could chat DS stuff
Feel free to send me a PM and we can work out meeting details if it'll work out.
