Is a Rottweiler a natural guard dog that can protect you without any training if you raised him and he knows nothing but you I haven't ever?

I very much doubt it.

Dogs have to be trained to protect a human, even Rottweilers.

A dog will usually be just as scared as you if theatened and will 99% put its own interests before it`s owners.

Dogs that nip and then back off, and run around barking are NOT protecting, as if threatened they WILL run away.

Your dog will probably be a good "watch"dog and warn you of strangers about....but protection dog?....Highly unlikely.

A PPD will grab an assailant and not let go until commanded. Thats protection. ok?

Maybe, but is more likely than not an untrained dog would be working out of shyness which is a fault in temperament to drive away a threat to its own safety by putting on a show of confidence and barking. It the attacker kept coming at some point during the incident when dog was pushed beyond the level of stress it could tolerate it would bolt which is a natural instinct to relieve stress and avoid injury. If leashed in which case it may hide behind its owner's leg for protection. If an untrained dog could reliably protect their owner from a real [not perceived] threat personal protection dogs would not command the prices that they do.

Very few dogs that are not trained personal protection dogs will actually "protect" an owner when faced with a real threat, even if they may normally act confident and bark at visitors and such. One of my two dogs barks at neighbors and strangers at the door or passing by out front, but when a man broke into my home late one night and entered my bedroom, walking right past the dogs on the way, he cowered in the corner and didn't make a sound. While he whimpered a bit when I started shouting, he didn't start barking until I'd successfully chased the intruder out of my home.

In addition, you should know that failing to socialize your dog with other people and animals is an accident waiting to happen. What will you do if he bites an invited guest out of sheer fear? While it would have been better to have socialized him as a young puppy, you can still work on it now, it will just require a greater investment of time and effort. A dog which is fearful of others is likely to avoid or hide from people they don't know unless confronted directly (as an invited guest, particularly a child, who wants to pet your dog is likely to do). People who mean you harm are unlikely to confront your dog.

Don't take any offence to this but if you didn't mention you were disabled, people would be saying why do you want a dog for protection bla bla bla. Which they are right. If you treat any dog with the love and respect it deserves then it will naturally try to protect you the best it can if it feels you are in danger. I have a brother and sister who both have learning difficulties so please don't feel offended, but people should give the same answer as they would if you didn't mention it. People think if they 'train' their dog with a ruff upbringing then they will have a brilliant powerful guard dog, which is wrong. Just care for the dog as you would/should to others and the dog may want try to protect you if you need it. I know it would be me trying to protect my dog. Buy a Rottweiler book and learn about the breed.

Dogs really need to be trained to do a specific task, there are some dogs that will of course be easier to train to do so. But ultimately, yes there will be some training, also there is a huge difference between an aggressive dog and a guard dog.

It all depends upon the dog and your relationship with your companion. I had a number of Dobes earlier during my life and if they are stable (not fear bitters or timid) and a couple of times I was in a threatening situation and my dogs growled in a way to make the hair on your neck stand up and lunged toward the man who was approaching me. Another time my dog was asleep in the back of my hatchback and for some reason did not like the way the guy on the motorcycle was looking at him woke up and hit the back of the window snarling.

This was before I had done Schutzhund training with them.

Another female who has a few screws loose, so to speak, a bite first and ask questions later sort of personality whom I knew well enough to not have off leash during normals hours, had her in the front yard when some kids cut through at 2 a.m. She was mid-air about to clamp one an arm and I called her back and she did not bite the kid and came back to me. Now these are unusual dogs with great breeding.

I do feel that dogs that have courageous personalities and good breeding will flip a switch and protect you when they sense real danger. If someone hurts them, as in break an ear, etc., then they will require training to have the confidence to continue an attach past fear or pain.

Often time a dog who loves the guardian will growl in such a way that no one will mess with them.

I worked in a battered women's shelter many years ago in S. Bend Indiana where women came from Detroit who said they would break into a house and just slit the dog's throat. I'm not sure how easy that is, but part of it depends upon how determined your attacker is. You had best have a gun as well as a dog.

Dog will draw confidence form their companion, ask any K-9 officer. But if you are afraid then your dog might pick that up from you. All depends upon the personality of the dog. On two occasions my dogs have saved my life, and I am grateful. But I would not depend upon it for all situations.

I think they need to be trained. But for most, they consider Dogs as perfect buddy. That is why they are considered as man's best friend. Naturally they are protector of their owner. but make sure that you treat them well.

No not at all, your dog will either run away or stand there and watch. Don't rely on him to protect you, it won't happen.
