<human>: I have a small rescue dog, he is 1 yo and has been with me for 6 months. He is dominant and has quite a character, but is a sweet guy. He shows no fear for anything and anyone, is really well adjusted, he is the playful and intelligent, high energy type of pup. Never been in a cage and has no terrible traumatizing past, just born on the streets and lived in temporarly homes till i met him.

At home he is golden and does everything he is told, outside he is ok and he listens as long as there are no strong distractions. 

When it comes to other dogs it's an issue. At the dog park he is often challenging toward other males (he never attacks first, but he approaches them with a hostile stance, sometime even growls).

That leads to brawls and he has already been bitten, even in a pretty serious manner, but nothing changed in his behavior. He is not better, nor worse (not more aggressive or scared. just the same).

On the street he always makes a big deal about other dogs, pulling the leash, barking and putting on the full show till i drag him away.

I tried the jolly routine most trainers talk about, but when my dog is excited he refuses food (even the delicious kind, yes), toys (squeaky ones too), everything. And he's not distracted or interested by silly voices, water on his face, stomping, clapping hands.

<bot>: how do you get your dog to leave alone other dogs, during walks and in the dog park? Any little known trick?
