Hi all -
Just thought i'd pose a question on a problem I am working on with Isis, my 2 year old. Lately (within the last 4 months) she has been starting to show aggression to other dogs when I am walking her in our neighborhood. Even dogs across the street she will go nuts and sometimes I have problems restraining her. It seems to be a territory thing as she is fine when I take her to pet stores or to the dog park/other people's houses - it is just when I am walking her around our place. And it also has coincided with her marking her territory around the neighborhood by peeing a bit here and there.
I take her out every morning and try to when I get home from work as well, although not every day. I use a halti and have recently incorporated a combination choke/regular collar - although I really did not want to do that! BUT after the last time she lost it and got out of her halti and I had her by a single string I decided I needed to make sure that didn't happen again! I have also tried to vary the route but in the morning there is only so far away from the house that I can go...
Any thoughts?
It seems to have worsened when I take her and our new little guy, Gage (pug) together, I am thinking that she is trying to protect him (probably). She has had general obedience classes and I am looking into getting her into more advanced ones with some of the trainers around here.
I am working with her as much as I can, have been trying to offer her super good treats as incentive to ignore the other dogs and to pay attention to me - have just started this so not sure as to results.
Thanks!
