I'm with Gina in this one, definitely there is a dominance issue there since you said:
ORIGINAL: Ratsicles
Once he starts with these behaviors, one of two things happen. If I spend the next few days sucking up to him, he'll return to his normal happy self. IF I get frustrated with how silly he's being, and yell at him, snap at him, or in any way show that I am upset with him, he gets worse. Much worse. Until I stop being snotty with him (usually I'm just stressed about everything he's spent a few days destroying) he continues on his downward path. 99% of the time, once I realize that I'm perpetuating the behavior and stop, it only takes a couple of days for him to get better.
What you are doing is pure submissive behavior towards him, if you "challenge" him by "yell at him, snap at him, or in any way show that I am upset with him" then for him you are "challenging" the status he already accomplish with you, you always give up by "once I realize that I'm perpetuating the behavior and stop" so for him he "won" the "challenge" every time
Now i am NOT saying you should be mean at him, but all that "sucking up on him" is absolutely not good for your case
Now when you "yell at him, snap at him, or in any way show that I am upset with him" you are just showing to him that you are unreliable, your emotions control you (i know is hard but thats the way he sees it) and he cant follow a leader that is unpredictible and might "snap" at any moment
One thing i am sure is that dogs
do not get offended, he didnt get offended because you got Culley, he might acted different because he wanted to show his status inside your "pack" to the new guy (a status that maybe was high already since the actual "leader" has being "sucking up on him" in the past), if Ogre ignored you that was to prove Culley that he was able to ignore the human that it was supposse to be the "leader"
When you do something that "offends" him of course he will act out, he cant believe someone with less status than him could be doing that, you are again "challeging" him.
I dont remember if you said how Culley is towards him but sometimes just a look can make a dog mad, now if Culley gives "looks" (even by just look directly to his eyes) to him that will make him mad, again, Culley actually maybe is not going to "suck up" on him as other members do and Ogre feels that Culley needs more discipline than others
Another example of him seeing you as an unestable member was when you freaked out because he was having the chicken in his mouth, for him he was doing something so natural as prey drive and didnt understand why you were acting so "irrational", another point for not seeing you as leader
He does not get offended because you toke Culley inside after the fight he is totally fine outside but the simple fact that a lower ranking member chalenged him was a big deal, now if you add that the lower ranking members teamed up and left "together" that made it worse, he just don understand why lower ranking members "chalenge" him all the time
NILIF =
IGNORE if he acts up again DO NOT suck up on him, if he needs to be like that for 3, 5, 10, 20 days thats fine but do not suck up on him, probably it will take a lot of time since before you were always giving up and it worked for him, you said you were doing NILIF before but it might be only half of it as you were not ignoring his tantrums by sucking up on him
Every time you suck up on him when he is upset you are
nurturing that behavior, leaders dont suck up on lower ranking members, do not feel bad for that, that will help him to realize that is YOUR house, your rules, your pack, not his, you didnt see but your were "feeding" that behavior, its ok, it happens way too often
"Harsh" techniques does not mean "Alpha Roll" and you should not to and alpha roll AT ALL
I hope you have NOT stopping taking him for a walk, that is REALLY important. You see, in nature, dogs spend much of their time walking as a pack, trying to find food and water. Their very survival is based on walking! Birds fly, fish swim, dogs walk. Walking allows them to have a sense of direction, a sense of accomplishment, a sense of pack comfort. The pack is all about structure and organization.
Domestic dogs live behind walls and no matter how luxurious those walls are, it's still totally unnatural to a dog. So the very best thing you can do for your dog to ensure a close, bonded relationship, a sense of structure and organization, and ultimately a balanced pet is to master the walk and do it often! You
bond with your dog every time you go out for a walk, not just exersice, but a
walk, that helps also the pack to realize better what is the hierarchy
When you adopt multiple dogs at different times, you must have a clear understanding with the first dog from the start – the dog is the follower, and you are the leader. Not part of the time - all of the time! Once that is established, only then can you bring in a second dog into the mix. Now because you've established a clear relationship with the first "follower” dog, the second dog should be able to sense that in this household, the human is in control. You will find then that both dogs will naturally try to co-exist with one another as your followers. But you might brought Culley when your relationship with Ogre was not as clear as you thought, if one member already was kind of challenging him, now he has to deal also with another that does not know how the hierarchy is and needs to be shown by Ogre
Ultimately, it's not about the dogs' relationships with each other, it's about their relationship with you and how you set boundaries and limitations. Once you have the two dogs understanding that concept, it will to be much easier to bring dogs number three and four into the home.
