My dog has become handler aggressive from poor corrections. What can I do to fix this?

I have been a big fan of your work for the past year and a bit. I am hoping that in my club that I can show your article to a few of my friends stating its source and not taking any credability. Basically showing a print off. I don't know if I can. Please let me know. Thanks

Also....

I have a dog that is very good, very trained and I love him but he has problems. What has happened and I repent everyday for it is that I have mis-timed corrections and severe corrections as in hittings and striking.

This dog is a labx with rotty. Very friendly and a soft dog. You know a small correction will do he is great really. But when I was hitting him and he is too soft and he has submitted ages ago I'm still mad and hitting him and in an agressive state myself and I take the correction too hard, he is now handler aggressive as in if I hit him on his nose, he will snarl with his tongue out, now in all fairness it is too touch and I shouldn't be hitting him and I've stopped, but what do I do about this tendency. The dog adores me and I thought it respected me. He won't do anything without permission and is very attentive to me. I recently got the BH Begleithunde, but this issue I don't like. I think it is just himself being defensive and not agressive but I don't know what to do. I was thinking a rank reduction program but my trainer told me to lift up the dog, for a long period of time not letting it breathe. I've read all your articles I think and I'm not sure what to do, how to this correction properly and sefetly without makign matters worse.

I would really love your help and would really appreciate it.

Thanks a million,
Barry
