Richie, I apologize if I misinterpreted your description, but I came to the conclusion I did based on this: "He was standing next to me so I reached down and slid my hand thru his collar, like I have done many times before, to scold him. "
in your original post.
I did not intend to suggest you had or were abusing your dog, but again I read that statement to mean that grabbing your dog's collar to scold him is something you do and have done many times/frequently.
""No apology necessary Tim."" Reading your comment sounded like my way of communicating with my dog was to throw him down on his back, which I have never done. I slide my hand thru his collar all the time, we sit and talk while I do this. Actually I should have made myself clearer, as he very seldom gets scolded. He has been the best he has ever been for the last week. Usually he thinks about any commands I give him and slowly does them, not today though, I put him thru his paces today at the request of my wife. To my astonishment every command I gave him, he did immediately, faster than ever before. I was amazed and told my wife as soon as she came home. She wanted to see for herself so I did it all over again and our dog did it again, kind of mad me proud.
Anyway, Tim I think we have cleared things up a bit. Thanks for your concern and information, I appreciate that. Richie.
I get that you love your dog, and your dog loves you. But as others have mentioned dogs need leadership, boundaries, and to be able to trust you to be predictable and stable in all situations. Treating them like a human, not so much. In fact, treating a dog like a human IS mistreatment. It's not malicious or abusive or ill-intentioned, but it just simply isn't what they need or thrive on. Dogs need structure and limits and leadership.
Now @Sabis mom
says, in a self-depreciating way, that she's a terrible dog owner because she lets her dogs do things that others may not. But I'd suggest that her approach is the epitome of good dog leadership! She has rules, but allows what she (and her dogs) like! Leadership doesn't mean stuffy, or rigid, or mean; it's more about being consistent, and fair but firm on those things that are rules in your home - like no chewing on my furniture, or eating stuff off the counter. Simple, clear rules, that are ALWAYS enforced. And again, not enforced by being harsh or mean, but by being authoritative in manner and insistent, and consistent. I personally don't ask my dog to do anything. If I say "do this", I never allow any dog to not do it, period. But like her, I have no problem with dogs having fun in or out of the house, and I leave them alone to do as they like the vast majority of the time!
Perhaps @Chip Blasiole
was spot on when he suggested that your dog is somewhat sharp-shy. I personally did not get that from how I read your description. But that might explain why your dog reacted as he did, especially if grabbing his collar to correct him is not something you would usually do...he may have felt threatened.
Either way, a good, balanced trainer can evaluate the dog and view your interaction with him first-hand and give you a much better idea of how to proceed with your dog.
I wish you both all the best moving forward!
