Dobies are one of my fav breeds! I wish I had at least one instead of the 3 GSDs (please note the GSDs are my "husbands" dogs that I have to deal with, could be part of the reason LOL) I had a Dobie X Rottie and she was the kindest, gentlest dog, unless someone tried to mess with her family. Even though I had kids after she was older, she still let them pull and climb all over her until she passed away at the age of 14. All of the ones I have known have been like that. It is a shame that some people feel they need to turn them and other protection dogs into killers, that they would not be normally.
I hope to have one again some day, but the 3 GSDs are enough for me right now.
