Please Help! Aggressive Puppy

Dogs with defense drive in them they don't back down. And if your other dog was trying to give Ruby a sign saying I'm the leader dog you do as I say and in return Ruby didn't take to kindly to that and put up a fight.

Yes but there have been other situations where there were fights. Sometimes over food, She used to growl at one of my dogs if she even tried to come in the room. One time my 4 year old decided to get herself Ice cream. I was in the other room not far away. I guess the ice cream dripped on the floor, Ruby was licking it and along came my other dog and Ruby just attacked her at my 4 year olds feet. We were lucky she was up on a step stool. I have told my kids if there is ever a fight to get out of the room as fast as you can. Other times it was the dogs playing and all of a sudden the play turned into a fight. Or a snack was left on the table and nodog but Ruby can walk past it or else. Or over a hole in the backyard. Sometimes they just walk past each other and I can see it in Ruby that she is telling the other dog to watch out. She puffs up, her tail goes straight up and wags stiffly and her hair stands up at her neck. Sometimes she attacks, sometimes she doesn't. we never know when she is going to snap. Sometime it seems like it's for no reason at all. I'm sure she has a reason, we just don't see it. We are going to keep working with her and see what happens. If it continues I don't know what we will do.

whoops, that picture was a little big. That was her when she was just a few weeks old. She is 95 pounds now.

Oh she is a darling looking dog! 95 pounds, oh my. Your last post did reveal more of her aggression problem. If she was in a shleter and was up for adoption it would defintly state for her not to be in a home with other dogs and even maybe small children. I wonder what is behind this issue. Were you her first owner? Have the oterh dogs always been in the same home from when she was a puppy? Did she act this way when she was a pup or just since she has gotten bigger? Is she spayed?
Do you give the other dogs more privileges that she may be jealous of? and I ask that last question not as inthe obvious freedom that the otehr dogs are allowed due to their friendlier behavior but in other aspects like....
do you let them sleep on the bed and not her? things that she might interrpret into alpha status.
 

Yes, we are the first owners we have had her since she was 5 weeks old. The other 2 dogs we have had since they were puppies too. One is a 9 year old Bulldog and the other is a 3 year old Old English Bulldoggie that looks like a boxer. The Old English bulldoggie (Lola) doesn't get locked up at night, the other 2 do. That is the only special priveledge she gets. None of them are alowed on the couch, bed etc.
Ruby started being aggressive at around 3 or 4 months of age. Too early I think. She used to growl at the other dogs if they even walked in the room she was in. I just worry about my other dogs and my kids getting hurt.

Well you have a very good reason to be cautious. I wish I could offer more advice, she is truly a gorgeous dog and I had always heard the breed was stioc, honorable but very protective and stubborn. Please keep us posted and keep up with the trainer....i'm sorry!

What a powerful website! so sad.
Do you own pittbulls? I used to have an American Staffordshire Terrier named Chynna, She was the best dog we ever had! She passed away last year from cancer. She was 9, a beautiful dog. Loved our children.

Yes, my girl is a red nosed pitty and a sweetheart. Yeah that video is very sad, I hesitted putting it as my sig but the more people know about the issue the better! This is my pretty pitty princess!

What a beautiful pup! I just love red nosed dogs. Ruby got her name because her nose was "red" as a pup. Great picture!

one attack on our other dog was so bad that we had to take her in to the vet because her throat was so swollen

 
It should be assumed that dogs who go for other dogs' throats, front legs, or bellies, in a way that does damage, really mean business.  You should take precautions at all times to protect your other pets.
 
Dogs that are aggressive toward other dogs are not necessarily aggressive toward humans, but it is also worrisome to me that your dog has gone after a human.  Sometimes that is due to a genetic predisposition to aggressive behavior (yes, there are a very few dogs that are born that way), or could be a result of being inadequately socialized (not blaming you, since I don't know how old she was when you got her).
 
Many Neopolitan Mastiffs are aggressive toward other animals, and, in fact, will not tolerate them at all.  Even in "packs" where the other dogs are of opposite gender there can be trouble.  Neo's are not usually recommended for families with small children, but that mostly has to do with their size.  But, if the dog decides to "protect" your kids against the neighbor children who visit your home, things could get ugly fast.  In fact, there was a case here in Massachusetts, not too long ago, of a child who entered a neighbor's home (where he had played many times before), and the family's Mastiff attacked him.
Please find a really competent professional veterinary or PhD behaviorist to help you assess your situation.  You need an impartial evaluation of the potential for danger.  My concern is that you noticed aggressive behavior at such a young age (are we sure this wasn't just puppy brattiness?)
The solution to your dilemma may be management, either behavioral or medical - or it may even be euthanasia, but you really cannot rehome a dog with any serious aggression issues.  There is a lot of liability attached to passing along a dog that is known to be a biter.
I hope you can find someone in your area that can do a proper eval on this dog.
 
 

we have had her since she was 5 weeks old

 
I hadn't noticed this before, but it is another area of concern.  She was removed from her litter and dam wayyyyyyy too early, and may not have successfully learned to inhibit her bite, or other valuable doggy lessons that create stability in the adult dog.

Until this morning, I would have based my comments on the ONE neo I've ever met in person.  But, I saw Anne's comments and oddly enough, there was a discussion on the BARF group about how agressive many Neo's are and how the gal who does the "last chance" rescues has to put down twice as many as she places......so, based on what I've learned this morning, I'm gonna agree with everything that Anne has said.
 
It would seem that the Neo world is not monitoring itself carefully enough and the bad temperment traits are being passed from one generation to the next.  This dog needs SERIOUS management.  A behavioralist is the first place to start, but yeah, I'd be very concerned about this dog around my children.

Yes, we did get her very very early, The breeder didn't seem to have a problem with it at all so we figured it was Ok.
We have called another trainer who hasn't gotten back to me yet and are talking to friends who own dogs, one who is a search and rescue trainer. Then we will make our decision on what to do. It is so hard because yesterday she was so sweet all day. Playing and goofing around with our other dogs (with a muzzle on) and my kids playing and loving on her. She smiles when we pet her and is so goofy when we tickle her big feet. It's hard after that to know what to do. One minute she is just a big goofy baby and the next a monster. We still love her anyway.

Yes, we are the first owners we have had her since she was 5 weeks old.

ORIGINAL: Ruby Doo
 
5 weeks is simply too young to leave the mother.  There is a HUGE amount of dog education that the mother teaches between 5 and 8 weeks.  Everything from body language to bite inhibition to general behavior responses.  So when the pup arrived the education that it got was through your current dog pack now.  Look back and try to figure out what they taught the pup.  Did they bully the pup away from it's food or toys?
 
I think you're handling everything well enough.  If I were in your shoes I would be investigating advanced obedience.  These Neos are pretty smart and they have a very protective instinct.  One thing to remember is that when your dog begins it's aggressive behavior don't reward it by stroking the back or speaking soothing words to it.  When you do that you are telling the dog "it's ok" and teaching it that aggressiveness is behavior you are expecting.  Instead, reprimand the dog verbally, get the attention on you, the alpha, and give a command (Down, Stay.)  and then a reward for following the command.
 
This will not be an easy road, but it will be a rewarding one, if you do your job well. 

Now that I think about it their was something starnge about when we got her. First she was only 5 weeks old, second the parents were not there, the guy said that they were in the middle of moving and moved the dogs already but not the puppies. I think it might have been because the parents were too aggressive towards people. Third, when we brought her home she did not cry at night, Almost every puppy I have ever had cried at night for their mom at least a few days if not a week. Which tells me that maybe she was already taken from her mom before 5 weeks. Then when we took her to the vet for a check up the vet said she had worms real bad from a severe flea infestation. She had to be treated with meds for them. I'm thinking this might be a problem within her. Yesterday my 7 year old was sitting on the floor. A drink had spilled and she was cleaning it up. Along came Ruby sniffing around but then right behind her came our other dog Lola. Immediately Ruby started to growl just inches from my daughters face. If she had not had her muzzle on she wouldn't have growled, just attacked and my daughter would have been right in the middle of it. This scares me!
