normal puppy temper tantrums or something more

Hey all!

i have a 9 week old terrier puppy that I got 5 days ago. He is overall sweet and doing well, great at potty training and learning commands, but he has a temper and is very vocal (growling, screaming, biting) about it.

I don’t want to give the impression that i’m not expecting puppy behavior and I was totally prepared for him to have an attitude, especially as a terrier. But I’ve had dogs and puppies (though this is the first that’s my own as an adult) and they’ve never been this vocally “angry”

I don’t physically discipline at all beyond just moving him to redirect and I don’t scream at him purposefully but I definitely use a stern voice when needed. For the most part we’re using positive reinforcement and timeouts if needed, but God, the biting is insane. We have frozen kongs, lick mats, interactive toys, regular toys, we’re doing training sessions, but he’s obsessed with feet, redirecting doesn’t work very well because he doesn’t care about anything once he remembers your feet. Again, I expected nipping and biting, but with the way he bites, he latches onto you and it’s hard to remember all the tools and tricks, you just want him off because it hurts so bad. I admit I’ve lost my cool and cried or yelled, but it’s just been out of pain. I feel horrible about it but I have bite marks that are bruising. I’ve seen all the videos and posts and tried so much but I feel lost.

But now, he’s started screaming when he doesn’t get his way. if you move him, he screeches. if you take away something, he screeches. if you tell him no, to stop biting, he screeches. If you pick him up during biting, If you redirect him… you get the point. I feel like this is all my fault and I’m raising a reactive dog. I’ve only ever heard those noises from my last dog (same terrier breed) once, when he got really hurt. I’ve felt around his body for pain points and nothing, he’s walking fine, eating, and his first vet checkup went great.

I’m sure people will say he’s cranky and I’m sure he is! I want to enforce more naps but I won’t lie, we’re also having a hard time with the crate training. He doesn’t settle down and again, the sounds he’s making are distressed, not whining. I’m trying to create positive associations with the crate and it’s certainly going but taking time!

To be fair, he’s vocal in every regard, happy or mad. But the sounds he makes when he’s frustrated or mad are so hard to hear. And he seems very happy 95% of the time. Like I said, I expect a certain level of this, and I know I’ve only had him for so short a time and he’s still getting used to things. But I just want to hear if this is normal puppy temper tantrums or something more. I feel like it’s my fault. Any advice welcome.
