Alright i work in a 3 dog kennel. We have two dogs that will get in a BAD dog fight if we let them out at the same time. The third dog is the submissive one with out a doubt.

Now the last few times i have not been taking my dog out with the submissive dog because for some reason the sub dog will bark/growl and pounce on my dog but the odd thing is my dog has NO reaction to this at all. He will keep walking and wagging his tail like nothing happened, once this happens the sub dog just walks away.

Explanation anyone?

The sub dog has the classic, bite-before-I-get-bitten-attitude. He has probably been bullied by the dominant dogs.
This is why Ed warns us to prevent our puppies and dogs from being attacked by another dog, because it will make them dog aggressive.
Even though your dog showed a marvelous attitude to the aggressor you should still prevent the other dog from attacking yours. Step between them and don't allow any contact.
What if the other dog had just torn into yours? It would be much easier to prevent an attack than break one up after it starts.

Oh don't get me wrong we don't sit back and say "Well lets see how this goes" When ever they get close to each other we step in between the dogs.

Before the dogs got along fine with no problems and recently this started happening for no reason. (am sure there is one but i don't know what it is) well as far as the sub dog goes being bullied i haven't seen it and we keep the dogs separated. he has spent a very good amount of time with my dog before and just recently started challenging my dog.

Does he have weak nerves or is he going insane?
Is he just reaching the doggie teenage years, and is experimenting with his boundaries?
Did he have a rabies vacination recently?

Hmmm, I don't know if this is similar or not, but I'll throw it out there. I have someone else's dog living with me (what else is new?) and he's been w/me for about 4-5mos. We (my dogs and I) have known him since he was about 8mos old and he's always been the easiest, least dog-aggressive dog in the world. Well, he turned 2 recently, and he's getting quite attached to me, so a few weeks ago, I think he decided to see if he could overthrow the local government (Caleb). Well, that didn't go so well for him. He was immediately pinned on his back and "yelled at" for about a minute. I went to intervene, but in reality, there's not much I could do anyway, and when I got closer, I saw that for all that noise, there should be some blood if this was for real. So, I squirted them with the hose and they both looked at me like I was the devil, and continued on. Caleb walked away after releasing Blaster, and Blaster came after him and kept trying to incite another fight, and Caleb acted like he was a fly. Now, they can't be around each other at all, b/c Blaster tries to start a fight. He stares at Caleb and growls when they're kenneled across from each other as well.

I chalk it up to testing limits/boundaries and coming of age. Caleb is not dog-aggressive, per se, but he is extremely dominant. He and Blaster have always gotten along extremely well, which was always sort of odd; I can't usually let Caleb run w/other dogs b/c he always manages to get insulted and then he has to argue...

He still ignores Blaster, as if he's not even worth fighting, or he doesn't want to fight him for some reason. While he won't start a fight for no reason, he is NOT one to ignore a dirty look, let alone an all-out attack. He had a hole in his ear, yet Blaster didn't have a mark on him. He merely pinned him, held him, and then walked away.

How old is this formerly submissive dog? Could he simply be coming of age and attempting to gain some rank over the others? Is it possible that the others see it this way too??? In the above scenario, these two have always gotten along beautifully, and there's about 2 yrs between them.

Sorry for the delay in my response. He just turned 6 years old, and he is, to be blunt, very weak mentally and physically. And no rabies shots recently.
