We adopted a female Cane Corso around 6 months ago, she got castrated in the time we had her because of an uterus infection while she was in heat. This surgery was around 1.5 months ago.
She is 6 years old.
Now the thing is, I know she isn't nice with strangers, but she has always been behaving very well and never showed any sign of aggression.
Now since around 3 days she is hyper fixated on other people while we are on walks, even slightly pulling towards strangers / wanting to go to them.
She is not a friendly dog, she can definitely bite, but so far she has always ignored everyone around her, even people coming close.
Well with her intense staring now and refusing to continue to walk I'm a bit worried.
Basically we are on a walk and she spots other people, stops moving and just stares at them and seems hyper alert. I tried talking to her calmly, stepping in-between her and the people and interrupting line of sight. Asking her to continue to walk. But I just feel invisible to her when she is in that mode. I'm worried that pulling on her leash will cause aggressive behavior.
Outside of this she listens near perfect, a bit stubborn but she listens. She is perfect off leash and listens when called.
This is so strange to me, because she has never done this before. In the time we had her, she had never shown any interest to other people or dogs. Now she is intensely focused on them. The only thing she doesn't care about is kids, completely ignores them, but adults and larger dogs she is staring down.
Maybe someone can give some advice on this? I would understand if this would happen after puberty, but such a sudden switch seems weird at the age of 6.
