I have a labrador, and when ever I take her for a walk she drags me along. She goes wherever she wants and I can't stop her because she is extremely strong. I just took her for a walk about 10 mins ago, and a little shih tzu was also being walked and my dog decides to pull me over to it and attack it (by licking it to death anyway lol). Its unacceptable behaviour and I really want to get her out of this habit. She's 5 years old, so is it too late to get her out of it? If not, how do I get her out of it? Thanks!
