I so agree, do not dominate this baby! I have problems with this tactic for the
bully breed anyway and think only experienced trainers should attempt it.
I also disagree this behavior is aggressive, he is a baby. His mother & siblings
would be teaching him for the next THREE WEEKS on proper behavior. Yelp
loudly, grab his neck fur, give a lil shake & growl then release and walk away.
Leave him for a few minutes, do this every time. I'm sure it won't be an issue
long. Pictures please of your new lil love bug!
