Over-Protective Female Australian Shepherd?
Hi - recently I have noticed that our female Aussie, 20 months old, has been showing some signs of aggression. We recently moved from a busy neighborhood in NYC to the suburbs where it is a bit quieter. We had her in Brooklyn starting at 10 weeks, where she was well-socialized with a group of neighborhood pups for regular play sessions and lots of exposure to a variety of people.
Now, it is quiet when we take her for walks and I've noticed she barks and lunges when she sees someone on the sidewalk. We carry treats with us so when we notice it ahead of her, we play LAT games and give lots of treats. This has been working.
Last week we had family in town and two other dogs - 9 YO male lab and 7 YO female. Our dog attacked the female immediately when we introduced them. We had to keep them separated/on-lead for the most part. When the other dog got close to me (I'm the mom), our girl went right after her and wouldn't back down.
I know around this time she is going through another development phase, but I don't want this to become a long term problem. She hasn't had trouble with other dogs in the past and goes to day camp once a week and loves it. Any tips? She's a wonderful, friendly girl and I just haven't seen this type of behavior in her before.
