My dog (Lexus), is a Pit, boxer, terrior mix. We got her from the humane society when she was 6 months old. She has always been FULL of energy, but has always loved all people and animals! Recently, she has been barking/growling alot more when people walk by. And now, she has started to bark/growl when some people try to pet her. It's always people she doesn't know, but she never use to do that! She was outside the other day and started barking at the neighbor, who was in the driveway. He went to say hi to her, and she growled, barked, and jumped at him. We have had many people over since, and she is fine with everyone. She is a little "overloving," trys to lick people and sit on their laps, but she is as nice as can be. But I'm nervous about how often she has been barking/growling at people. I feel like she is starting to be aggressive.
I don't know what to do! Nothing else has changed, but I'm afraid it will continue or get worse! What can I do to stop this? I don't think she would ever bite anyone....but since this new behavior, she is making me question it.
Someone please help!!!! Any advice would be much appreciated!
