I'm sorry if you feel like I'm attacking you. I'm not. I am just telling you what I think.
I have to be honest here, and say that I agree with FIC 100%. It sounds like you are trying to make this situation seem less severe than it really was.
A "nip" is a bite. Plain and simple. Whether it just left saliva, it bruised, or it caused him to go to the hospital, it's a bite. So your dog bit that person.
A torn ear is a bite. Not "tore the ear a little". A bite, and hard enough to draw blood. Yes, ears are a common area for injury to happen in aggression cases, but that's besides the point. It was a dog bite.
You said the dog slipped past you a number of times. Once is forgivable. Twice you start to question. But several times? Even though these things happened over a period of years, it never should have gotten past a second time. Putting a baby gate up (preferably two!) will prevent slipping out of the door. That problem is solved.
Human error is inescapable. I know this from experience, believe me I know it. Humans will always find a way to mess up, no matter how many times they say "I'll remember next time". You're tired, you thought somebody else shut the door, you thought you put the other dog in the room - no matter how OCD-like you are, human error will happen. You have to set your home up so that even in the event of human error (Oops, I left the door open) - there is a back-up measure in place to prevent anything from happening.
Nobody says these things to try to make you feel bad. I say these things because I've been there, and I know what you're feeling. The stress, the frustration, the anger. It's all normal to feel that way. But you have to take it, and apply it, and learn how to live with the dog you have now. Not the dog you wish you had, not the want you want it to be, but the dog that you have.
Gaci, my human-fearful girl (thank doG she's a flight dog and not a fight dog with people), once had an issue with other dogs. Rather, I would say she always has the issue, but through work the problem is no longer present. She used to get intolerant with dogs quite easily. This, combined with a resource guarding problem of the bed, caused some problems in the household. Her resource guarding was strange though. If another dog was on the bed already, it wasn't a problem. If they all went into the room together, it wasn't a problem. If Gaci was already in the room, though, and other dogs came in, that was the problem. And yes, in the end she did end up biting another dog. After that, management was in order. Because I knew her triggers, it was easy to prevent the problem from happening. Some ways I managed the problem:
- If she wanted to spend some one-on-one time with me, I would have her in by herself and shut the door.
- At bedtime I made sure the dogs went into the room together so that she wasn't already up there (I have indirectly taught a cue in which all the dogs that sleep in my room will break off from the others at bedtime cookie-time and wait in my room).
- In the morning, mom would sometimes let the dogs out before I got up. If that was the case, she would let the other dogs in my room first, and Gaci in last.
- If Gaci was already in the room, I would get out of bed, ask her to leave the room, and then the dogs could all come back in together.
As silly as some of those things seemed, such as asking Gaci to leave the room just so she could come back in again, they worked to prevent the problem. Once prevention was in place, I began working on the problem. Since it's a different type of problem, I won't get into the details of how we fixed it, but it has been a long time since she has bitten a dog, or shown any resource guarding. Her tolerance for other dogs (in specific situations, 95% of the time she loves other dogs, the other 5% she can't stand them in her space, that number is now down to about 1% or even 0.5%) is increasing, and I can read her like book to know if she is becoming intolerant of somebody in her face/space.
The point is, you do what you have to do to prevent the problem, no matter how silly, or no matter how much you think you will remember in the future, you make sure these things do not happen. And to remember that some of us have been there, and when I make note of the importance of management (and I have to be honest and say management must become better), it's not to harp on your or make your feel bad, it's to make you understand the gravity of the situation. And this is a serious situation, I think that because you have lived it for six years now you have become used to the issue, and dog aggression is an issue unfortunately you can never afford to simply get used to.
