My name is Brutus!

Brutus is a full breed American bulldog with birth records. He turned 5 years old in September. He is fully house trained, and crate trained. He knows sit for his food and when told otherwise. He is currently due for his rabies vaccine. His downfalls are he has aggressively come at my son and I as of lately. He also barks to gain attention and will not stop and jumps up on people when entering. We have worked many different techniques to try to correct these behaviors, but they have been unsuccessful. He also has to be tied up when let outside as he escapes from my chain link fence and runs. He would do better with a wood fence or large land to roam. He has done well with other dogs in the home with adjustment. He has never went for our cat inside. He does chase squirrels and such in the yard.
