On trips to the dog park my terrier has become aggressive towards other dogs. Particularly non desexed males and any puppies or younger dogs.
After a number of embarrassing encounters I have realised I have a problem - which I'm fully aware is my fault through lack of training and obedience.
So I've been reading everything I can on dog obedience and training. It's sounding like underlying the aggression in an obedience issue, I have a dog who doesn't recognise me as the boss.
I have been reading the K9pro site and trying the NILIF method. I've been able to get my dog to sit and wait for food, entry to the house, attention pats etc. however I took him for a walk to the park (I realise it was probably too soon for this) and tried to get him to sit at the gate before entering. He would not sit. I stood at the gate asking for sit for 5 minutes, he would not even look at me. So I took him home.
Again I know it was probably too soon for this activity, but I'm interested in what was actually happening. Was he simply too distracted and his obedience not yet developed for such an activity or perhaps it was an act of defiance?
