I got my puppy Abie at around 8 weeks old and he was always a nibbler but he also was very loving so I thought he would grow out of it when he stopped teething. He was born into quarantine so he’s never been out on a walk (my neighborhood isn’t safe at all so I can’t walk him outside my house) but I never thought that would be an issue since my backyard is pretty big. He is now 5 months and even though I do everything I can to make sure he’s a happy puppy, he does this thing that I don’t think any other dog does and it’s so bad that it gives me anxiety. So I’ll just go out to the backyard to play with him or when it’s time for me to refill his food bowl, and he’ll come out and jump on me and lick me and everything will be fine until like 5 minutes in when I’m playing with him he’ll start to run circles around me like he’s a shark in water or something. Then I’ll try to get him to stop by saying “sit. You want a treat??” And I’ll keep repeating that because I know what’s coming next, he literally bites my leg through my clothes and one time he even got his tooth stuck in my clothes doing this, and he will just bite me multiple times and so hard while I try to run in the house and it just won’t stop. Every day he does this and I don’t even provoke him. Someone please help, my parents are threatening to give him away but I know that he’s not himself when he attacks me. I don’t know how such a tiny little dog can make my legs bleed and I have bite marks everywhere. He’s gotten all of his shots too and I just can’t figure out why he does this.
