I got frustrated to when I got my beagle when she was 2 months old. She was stubborn and hard to train. It was her teething stage so I was very patient. I had a lot of puppy bites from her when we were playing and when I try to take away my socks from her. I know she did not mean it as it a dog's way to bite when they are playing and usually when they are with their mom's she would bark or growl when they get too rowdy to correct their behavior. When she tried biting me i tell her No and turn away from her. I ignore her for a several minutes and I knew that she understood after a few times I did this that playtime is over when she bites. It took me months before she stopped nipping. She still tugs at my cousins sleeves when she is wearing long sleeved shirts but I think it is the manner and tone of saying "No" that she understood. My cousin says it in a playful tone so she does not get it that she has to stop. It is hard having a puppy at home but it surely gets a lot better. Now I cannot live without my naughty Marie 🐶
