Yes....but it will be very shallow. :(
A dog that has been raised properly, has not been mistreated, has been trained properly and socialized regularly is one that will be " the most un-dangerous dog in the world"
If the dog is socialized and kind then there is no problem but everybody should know that even the most trusted dog can notbe left alone with a child unsupervised.It wouldn't take two seconds for a dog to snap and then it could be to late to help the child.Make sure the boy is the dominant one over the dog and make sure that happens early.
A poorly bred speciman plus add in - not socialized, not obedience trained, ignored, abused, etc. There is no one breed that attacks its owner. It is the dog that fits into some of the above categories.
One human year is the equivalent to 7 dog years.
The popular comparison is one human year equals seven dog years.
7 dog years is one person year
This depends on how well socialized your existing Pit Bull is. Providing it has been well socialized with other Dogs there should be no problems, but I would not suggest having two Dogs of the same sex - especially two males. It would be a good idea to get a puppy of the opposite gender to your existing Dog, just make sure you neuter/spay at least one of them to prevent unwanted litters.
Yes, if it is a really mean dog, especially one that has not been socialized properly and/or has a very strong territorial and protective nature. Dogs that have been teased so they get deliberately aggressive towards humans are also prone to being able to kill a human.
one year
7
I believe every 7 human years is equal to 1 dog year
Ther are 20,000 dogs put down in one week for dog fighting and 400,000 in one year for dog fighting.
