I just got my American Bully about two weeks ago, and I had to take him to board him last weekend we had to go out of town. While he was there they nuetered him. Before he went there he was pretty people friendly. He would growl when someone first came in but once he realized we were ok then he was ok. Well he growled at my vet the whole time he was there and growled at me until he got a good look at me...then he was fine. Yesterday when my mother in law came to clean the house he growled at her continuously. I really dont know how to deal with this because we host a lot of company and have young children that have friends over all the time. He doesnt really dislike my husband, but as far as doing anything for him (such as coming when called); forget it! Also and this is my largest concern. I have a 4 year old son that has been away at his dads since before we got Alex; he wont be back for another couple of weeks. I am affraid of what might happen when he gets back. Any advice would be wonderful. Honestly I am a little taken aback by his behavior...both of my prefious bullys were agressive towards other dogs but not towards people so much.
