He should definitely play and exercise but shouldn't act stupid.
Zaidoo, what do you mean? Dogs are animals. They act very juvenile. My old Lab was 14 when I had to put her down a little over a year ago. She was still acting goofy and silly at times, when she was physically able to. Do you know that domestic dogs are paedomorphs of wolves? That means that they retain the juvenile qualities of wolf pups and never reach the the maturity of an adult wolf, their ancestor. Dogs, as adults are more playful, by far than adult wolves. Dogs bark like wolf pups. Woves rarely bark as adults. Even their biochemistry is different from a wolf. Dogs have higher levels of neuro transmitters like seretonin (the stuff that makes us happy)... and other physical characteristics. Dogs just plain never grow up. LOL. Dobermans in particular are one of the most undignified, goofy, silly, ridiculous dogs I've ever had. We're talking about living things here. Not robots that you can turn on and off. LOL.
What you want, what you describe is painfully unrealistic, I hate to say or dampen your enthusiasm. You want things which contradict eachother, which are incompatible....which don't happen with dogs. For instance...if you have a visitor who comes often to your home, any healthy, normal dog is going to become accustom to them, get to like them and not react the way you're wanting them to. No living thing with a brain stem will act the way you want because it goes against the scientific principles of learning behavior, like habituation and the law of effect.
Do you know what? I had a boyfriend a little over a year ago and I broke up with him. Lyric knew him well and saw him often....liked him. After I broke up...maybe a couple weeks later, I was gone and this guy came into my unlocked house and went to sleep in my bed. He had been drinking. I came home and my house was full of propane. He had turned on the propane stove (not sure if it was by accident or not). I came in and the place was all foggy. I quickly turned off the stove, opened the windows and shooed the dogs outside. Then went and yelled at this ex boyfriend. If I had come in with a cigerette, well...you know the rest of what would have happend. My dogs knew and liked this fellow and they knew no better. Lyric would have had to have some incredibly fancy training to know what to do in a case like that.
Why not get a good electronic security system if you live in such a dreadfully high crime area, a .38 or .44 mag and get yourself a dog as a companion if you truly love dogs. If it's not for the love of dogs, and for other reasons, it's not a good idea for you to get a dog.
You have to truly love them...deep in your heart, love their
imperfect, goofy ways, their individual personalities, their forgiving, loving nature, their playful and mischievious ways, their innocence, the fact that we don't speak the same language and it's difficult to communicate with them, the fact that they don't think like we do or care about the same things as we do. You have to put up with a certain amount of destruction in your home and garden and have untold patience with them because until they are trained and even then, they are animals, not humans, not machines. They're not as intelligent as we are intellectually and we have to keep that in our minds all the time because people tend to expect far too much out of their dogs and then they punish them when they're so frustrated etc, etc, etc.
You have to be willing and wanting to give them everything they need because they live to be with their family. They are entirely dependent on humans. Do you know that a domestic dog will never make it in the wild? Even so called wild (feral) dogs depend on the proximately to humans by scavenging in garbage around villages and such.
We owe it to these animals which we have basically created to give them what they need to be happy. These domestic dogs which have lived with humans for tens of thousands of years are basically man made friends. They're neither wild or human. They're somewhere inbetween... almost. The ancient people thought they were the messengers between humans and the gods.
It's not fair or moral to get a dog and not do right by it.
I know you wouldn't mean to not do right by it. But from what you've told us, it does not sound like you're nearly experienced enough yet or that you have developed sound reasons...good reasons for having a dog...any dog, but especially what you're describing.
I think it's great that you're asking questions and we're all talking it over, but I recommend that you do some more thinking and get a better understanding of dogs and what it is you
truly want. It may not really be a dog at all that you're needing.
What is it that you fear which makes you want protection? What kind of place do you live? Maybe we can come up with some other ideas in the meantime.
