At 5 months old me and a friend of mine worked with a local trainer that came highly reccomended to us.
1. He said to use a choker, and "a puppy started on a choker should never need to go to a prong".
2. "Never train with treats, ween your dog off treats if he's already trained that way or he won't listen to you unless you have a treat in your hand, a monkey could train a dog with treats".
3. He skipped the "learning" and went straight to "correct for disobedience" on my 5 month old pup.
Personally...
1. I still used treats, but I used them less because I was told not to use them at all.
2. After a few months of my dog not responding to a choker when teaching him to not pull and "heel", I stopped using it because it was ruining my relationship with my puppy. He was very clearly mad at me after using it on walks, wouldn't lay down at my feet, walked away from me when I laid down next to him on the ground etc.
3. Although he gave me alot of insight into training and got me started on the correct path... I totally wish I could do it over again. I often feel like I screwed up the puppyhood experience by being too tough on my pup, even though I seem to only be thinking about the few negative moments opposed to all the positive ones, I keep trying to remind myself of all the happy experiences I gave my pup.
At 7.5 months (2.5 months after starting him on the choker) I stopped using it and decided to let my puppy be a puppy. Then I started using hotdogs in training, like my breeder had told me to do in the first place. I spent 3 or 4 months doing purely positive training with him, making training sessions as fun and exciting as possible for my dog, working off the "Building drive & focus" dvd's methods to build up my dog's drive and training obedience thru drive by playing tug.
At 1 year old I bought a prong collar, it worked pretty well but wasn't perfect. A few weeks after switching to a prong collar, I went out and bought an e-collar because it was driving me absolutely insane that my dog, the lil ****head that he is, would run away, stand 30ft away from me n ignore me completely when off-leash. He wanted to run around in the grass n play, I wanted to go to bed... the e-collar fixed this in 10 minutes, once he knew he wasn't immune to correction at 30ft away or without a leash attached to him, training got alot better. Side effects of teaching him off-leash "come" was that he finally caught onto the whole "Fetch" concept, and he finally started listening to "heel" (previously the only way to stop him pulling on the leash was to let him drag the leash then step on it when he walked ahead of me, holding the leash would make him pull).
So now I use low-level stim, lotsa hotdogs, tugs, and have a dog that I can trust to walk out and get the mail with me without having to worry about him not coming back inside with me. A dog I can take into the back yard and play fetch with and has alot of drive. A dog that I can take out on a 20ft Flexi-lead to let him sniff around, but at the same time have him heel next to me perfectly when walking thru a crowd. Training with a new method and adapting it to what my dog was telling me with his body language made a world of difference.
I've discovered what works best for my dog, I've made my mistakes and hope it didn't have any long term effects on my dog. Our relationship is perfect, he's as happy as he could be, he has excellent drive and his obedience makes me a much more relaxed handler, although I still get frustrated when he makes me walk in the rain then won't poop <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
This was my dog training experience, I still haven't been able to work out if he's a soft or a hard dog, I'm assuming soft-medium depending on his determination to sniff the grass. Unless I'm misunderstanding something, the only "trick" to training a soft dog is to read your dog and figure out what he's responding to the best. Every dog is different, and they do a better job at telling us how they feel than I gave them credit for.
