Hi everyone. I would really appreciate hearing some advice from any pet parents that experienced similar behavioural problems with their pets. My 11 month standard poodle suddenly started to show unjustified signs of fear around strangers. In fact, she is tensing up and pulls on her leash sometimes towards (aggressively) or away from (skittishly) the passing people. Nothing unusual happened to her to trigger this. Is this normal teenager behaviour that shall pass? Did you experience that with yours? She was friendly and happy to be petted by strangers, especially by children. She was properly socialized since she was a puppy, street walking and dog parks. Also, the day after tomorrow she`ll be undergoing spaying operation. She had her first season in August. Will the spaying help or worsen her behaviour, as I`ve read about female dogs that show aggression increase afterwards?
