I have a two year old male boxer (Chet) that has become agressive towards children and male adults. Chet goes crazy if a stranger (pizza man, UPS driver, etc...) walks up to the door. He will jump completely off the floor trying to jump through the window. This type of bahavior started about 4 months ago and has become even worse. He recently bit my 9 year old while they were playing. My 9 year old was sitting on the floor in front of Chet and my wife opened the door behind my daughter to throw away some food and Chet lunge after my 9 year old as if she was taking food from him. He didn't break the skin, but it was a scary moment for my daughter and my wife. We called the Boxer Rescue and they will not help because he bit my daughter. We called the local animal shelter and they said they would put him to sleep. My wife and I are torn, we want to find him a home but don't know where to turn for help. If anyone has dealt with an issue similar to this, please share your comments with me. Does anyone know if a behavioral trainer can correct Chets aggression. Any help is appreciated.
