Another alternative is the Dokken dummies. You can buy them in any style of duck you like - we started a reluctant Golden on Saturday with a Dokken green-winged teal (a small waterfowl) so he could easily get his mouth around it. After a little while he got really excited about it. I inject my Dokken bodies with duck scent (and boy does it smell!) which the Dokken people are happy to sell to you!
I feel sure there must be a UKC hunting retriever club near you that would love to train you with your dog. Here is the UKC Hunting Retriever Club directory. That's what we have done - Shelley is not the high-style field trial dog she could have been if I had sent her off to a professional - but we have a lot of fun and she's good to go as far as hunting. (She had a wild time with a live pigeon on Saturday - the pigeon certainly did not enjoy himself, but she did.)
Thanks for the info. I'll see what I can find. My husband would be thrilled if Max could learn to hunt, and Max would enjoy it too.
