My friend has a 5 year old female pit. When she was a puppy she was fine with dogs, at about a year and a half she started to become aggressive. It wasn't with all dogs, usually just new ones, and sometimes if play would escalate with some of her older friends.
She has noticed recently that the dog aggression seems to be disappearing. She has not snapped at another dog in about a year, and has actually met a few new dogs, including another female pit bull, who she was all fine with. She even ignored Venus who was in her crate when my friend stopped by a few weeks ago.
Both of us are perplexed as we had always been told that pits can grow into their aggression . . . but she seems to be growing out of it. Any thoughts on this?
