Please help me. I am sitting here writing this in tears as I'm stressed out about my new puppy. She is almost 9 weeks and we've had her for almost a week and it has been alright so far - she nips and chews as expected and has a lot of energy but this morning has been so terrible and I'm at my wits' end. My hands are covered in scars and my feet will be following shortly if this doesn't stop. She will bite me all the time and I have tried to yelp, praise her when she lets go and give her another toy but when she is excited she just won't cooperate. She bit my foot hard today and I yelped, she bit harder so I yelped louder and soon enough I was basically barking in her face trying to get her to stop. In the end I just had to wrench her mouth open with my hands to get my foot out. She then pounced all over me trying to find somewhere else on me to bite. I have tried using a time out area but it doesn't seem to work. She might be calmer for about a minute but then she just goes back to biting me. I feel like it stresses her out as well because whenever she is confined she gets very vocal and will continue barking and whining for ages after I take her out. I've spend the whole morning basically screaming at her (and she screaming right back) so that she'll let go of me and I feel so guilty and like a total failure because I can't seem to teach her what to do. She must hate me because all she does is bite me and run around chewing everything she's not supposed to. I think she's frustrated at having less freedom than she's used to. She barks when she's on her lead and can't get to where she wants. She will bark and whine when I put her in her crate even though I am sitting right next to her. I've been trying to wear her out by running around the garden with her (and I'm worrying that this is encouraging her to nip at my feet even more) but I'm so sleep deprived from being up 3 times a night to take her out and get her to sleep again that I have no energy. I spend the last 20 minutes sitting cross-legged in the middle of my living room and crying. I knew it would be hard but I thought I could handle it.. and I have no idea if what I am doing is right or wrong. I want to teach her to grow up to be a good dog but I feel like I'm failing and it's really upsetting me Please, does anyone have any words of encouragement or advice on how to make her behave?
