My 6 month of puppy has been doing really well with training the last week or so but lately she’s been horrible. If I don’t give her attention she jumps on my and bites my hand ( not play biting). I walk in the house she bites my shoe laces. Walk with socks she bites my socks. She counter surfs non stop. I lost my mind when she was 3 months. Started to gain it back, but I’m losing it again. What should I do?!
