Mikey, wow!
I always learn a lot from your posts ... no matter how much I think I already know!
Good timing on this one too, Farmer (Beldin's new little brother) is just turned 7 months old - and completely different than how Beldin was at that age!
Thanks for all the info and links!
Wendy, good luck with your pup. I know sometimes it can be really frustrating ... and also I know sometimes Beldin (and earlier Mocha) did seem quite a bit more "hard-headed" than other dogs I've owned and trained successfully. --- But, like people, dogs are also individuals with their own unique quircks and attitudes. What works very well with one won't necesarily work with another (even though there are some general rules of thumb).
I hope you don't give up on him.
