MichaelM, it's not hysterics setting in
Ive had dealings with this type of dog, they need to be owned by someone who has had thorough alpha-male training and not some numpty who hasn't even had a yorkie dog before. I don't think dogs are born bad, owners tend to make them that way unfortunately.
Which type of dog? The OP doesn't know what it is and describes it loosely as a Wolf dog.
Wolfdog is a generic term applied to a number of breeds - quite recent breeds not recognised by the KC - which are purposely bred to resemble a wolf - Northern Inuit, Utongogan, Tamascan etc. Typically, they are some variation of cross breeding Siberian Huskies, Malamutes & German Shepherds.
There are some breeds that did use Wolves in the origins of the breed - CSV, Sarloos - these are recognised breeds and are now many generations removed from the wolf.
As for the Alpha male training comment - treat a Sarloos in such a manner (cautious, reserved) and you'll never gain it's trust. Treat a CSV in such a manner, you'll probably come off second best.
