Hi everyone! Looking for a bit of advice here We have a new little puppy (had her just over a week now!), just over 8 weeks old so still very young. She was separated from her mom a little too early, we know, but circumstances were difficult but she settled in within a couple of days here, with seemingly no separation anxiety! (Edit: I should also point out, for the first couple of days with us, she was an angel, just a bit of overexcited scratching and nipping when playing) So far, she knows her name already (though picks and chooses when she wants to come when called!) and she knows 'sit' relatively well. She's learning 'come' and 'leave' on some occasions and she'll go potty outside if we take her out but she's not quite grasped asking yet, but she's also very, very feisty at times. She tends to keep going for hours, and then will stop and crash for hours, but in the time she's awake she can be a handful when it comes to biting and scratching. She'll bite and chew absolutely everything within sight almost relentlessly. If she's chilled out, she'll listen when we tell her to leave something alone, or she's easily distracted with her toys or a treat, but once her mind is set on chewing something, she just wont stop. We've been trying everything from distractions, new toys, different treats and we've just bought her a playpen for time outs, but we're struggling to get to grips on how best to use it without stressing her out too much. She seems to throw 'tantrums' of sorts, too! If we tell her no or pull her away from something too many times, she will immediately start on us instead. I wouldn't say it was direct aggression, more like overzealous play, but we just aren't sure how to go about calming her down or stopping it. Any tips or advice would be greatly appreciated! It seems to be particularly after she's been awake for a little while, and every single night when we bring her up to bed even if she's been sleeping most of the evening.
