Hello Daniel and everyone,
I am writing because my 8-month-old havanese puppy is showing early signs of aggression. The first month we got him he was great!... a little hesitant toward strangers, but still friendly, joyful, and loving. He is still that dog with me and is very smart! He is well-trained and picks up new behaviors quickly... which is probably why he has started growling and barking at strangers and nipping at their heels. He has learned over the past 5 months that I've had him that these behaviors keep strangers away.
I have started re-establishing myself as the alpha dog. Cody is very well socialized, so this seemed like the only issue. He has never slept on my bed (he is crate trained), but has been allowed on the couches and the bed since he was little. Starting last week, I am the first person to walk through the door, and he must sit and wait until I say, "Ok!" to follow. We are working on him staying off the back ledge of the couch (his favorite look-out point) and keeping him from attempting to stand on us to gain height advantage. Often, we have staring contests and I make sure I always win.
I love my dog more than anything and I would do anything for him, but aggression trainers cost more than I can afford right now. Do you have any extra ideas for us? I think he will learn very quickly once I know the right method to use.
Thank you!
Cody's Mom
