[RachelandSadie]

i understand where you are coming from. i have been bitten pretty hard by Sadie when she was attacking my other dog and reacted stupid by swatting her butt. i felt stupid, it was an awful feeling to know that i had struck a 6lb dog, it wasn't hard, but it was foolish of me. i called my professional training friend the next day for help.

it's hard sometimes not to strike when something strikes you first, but you have to hold it in and not hit back. hitting him will make him more aggressive because he's getting aggression in return. you'll have to teach him to stay when you go outside so he doesn't chase and bite. and you'll have to get a trainer to help train him that biting is wrong and doesn't get rewarded but sweetness does.

good luck and it took a lot to admit that you made a mistake and smacked him. you aren't the first person to react to something like that in the wrong way. never a good thing so just train him well from now on and don't let yourself loose control and do it again. sorry you were bitten please make sure that you have a dr. check it out because infections can spread in them pretty quick.

(added, i only swatted Sadie lightly on the butt, you said you back handed and threw the dog and if that's what happened was abusive behavior towards him, i know you didn't mean to, but please make sure it doesn't happen again)
