Meggy was abandoned outside our bookstore last year. Having no luck finding her owners, we decided to keep her. She was about 6 months, fairly emaciated, and full of anxiety. We are certain she is a german wire haired pointer but haven't identified what she is crossed with.
She has shown to have moments of interdog aggression and with strangers, though less often . We really have found no pattern, other than she detects fear or a lack of confidence. But this can't be universal. She is a sweet looking thing - not convincingly scary in appearance. Her leash, small dogs and baseball hats have been possible factors at times, but not always. I have never used aggression with her and she is both well fed and heartily socialized and exercised. Also, her anxiety has passed largely, she's generally very calm, and always friendly to people who visit our home.
She makes a scene with about 1 in 20 dogs and 1 unsuspecting person in 1000. We live downtown where she encounters many people and is exercised in a popular dog park. She is now about a year and 6 months and is listening better each day, but there are times which I am either distracted or not right at hand to handle her. Furthermore, I am beginning to feel some anxiety with each new person or dog we encounter and this may only be aggravating the problem.
