Absolutely not! These classes are for everyone! Any dog, no matter size, age or breed / mix. Even blind, deaf or physically impaired dogs can play! It's the Best Game Ever! 

Yes, if you choose to compete, these classes will help you to get ready! 

If you do not intend to ever compete, you can use whatever target odour you choose! 
But if you do intend to compete, I would suggest you use the oils approved by Sporting Detection Dogs Association (SDDA) and Canadian Kennel Club (CKC). Check out my free course on Scent Kits for more info!
