Hi,
I am having a problem and wonder if anyone can help. I have tried really hard to establish myself as the pack leader in relation to my dog, a staffy/kelpie mix. I got him from the pound a few months ago, he is now 18 months. My dog has become extremelyt obedient, due to consistent hard work and effort - everyone comments how receptive he is to my commands etc. and he is exceptionally well behaved except for one thing - he has started to be aggressive toward new dogs at the dog park, which I now avoid. I understand that a loose pack forms between the regular dogs at these parks, but what I don't understand is why this is the only thing my dog really does wrong! He is respectful of my authority as the pack leader at all other times, except when in this situation. even when he does it, when I call him off he comes straight over, and depending on my tone of voice, sometimes he will come straight over and assume the submissive position on his back. This is good, but the aggression has already happened. I would really like to return to the dog park, as he gets along really well with the regular dogs, and has one 'friend' in particular who he wrestles with the entire time they are there together. Any suggestions/explanations?? Thanks.
