I have a purebred 13 week old GSD named Coco. I have hired a trainer to help me train her to stop biting me so hard (she has drawn blood and just clamps down no matter what I do) and to help me stop her from coming after my 7 year old. I have to keep them separated majority of the time otherwise she is nipping at my daughter thinking she is a littermate wanting to play.

No matter what I do with this dog when I correct her she gets very mad and comes after me with full force. I have tried to leash correct her and she gets pissed off and comes after me. I have tried positive reinforcement but when I correct her she comes after me still. I have tried,.per my trainers suggestion not mine, a shake bottle but again she comes after me afterwards.

She is definitely an Alpha or tries to be. My husband just lets her do whatever and she is very sweet and loving towards him. I think maybe all the corrections have made her believe I am aggressive or something I'm not sure.

I have scars and puncture marks all up and down my arms and hands from her. I don't mind the biting except when she bites so hard she punctures my skin and my daughters. She doesn't really bite my husband too much.

Does anyone have any training tips that I can use for her? Or a way I can build a bond with her? I know deep down she is a very sweet and good dog. I'm just having issues with her being aggressive towards me and I want to nip this in the bud before she gets bigger and I will be forced to rehome her.
