Hello all who read this post.

I was hoping to get some feedback on a teaching method i have applied with my Dobermann puppy of 4mths.

When feeding my puppy at meal times, the puppy knows to sit and wait untiol i give the command of "have it" before eating her food. I also use this method when hand feeding a treat.
I have even conditioned my puppy with the "exact" word, by this i mean that i trick her by saying other words in a similar tone and she waits until the correct word.
I have also used a command for her to stop eating, or spit out a bone etc.
This all works well, and she seems to have developed great confidence in knowing how to comply.
I have high hopes for my puppy in obedience trials, and i was wondering if anybody may think that this method of teaching could be bad in some way. Bad in such ways as lowering food drive etc. or if given a treat after performing a newly taught command, may concentrate more on the desired words "have it" rather than the new command.

Just looking for some opinions on the possible ramifications, or even other ideas that people may have.
I know there are alot of members of this forum who really know alot about the psychological makeup of canines, i would really like to hear from some of you guys aswell.

Thanks in advance to everyone.

No that should not lowering food drive or anything like that, but you should use only one word to let the dog knows that the exercise is over and that he can get his food or treat now, use the same word "have it" to end all exerice and then give him his treats so that it will be like a conditioner, you should also use "have it" to mark good behavior when training new exercise, like if you are teaching him to down fast, as soon as he is down you mark it with "have it" and treats.
Good luck.
