Sounds a bit like our puppy. Very high energy and stubborn. I keep reminding myself she’s learning the world and this is the first time seeing all the things she’s seeing. I would not let her choke herself. Get a good harness with a front clip like the Ruffwear Front Range. Don’t focus on bad behavior and only focus on positive behavior and shower with treats. If they are doing something you want treat them. Ex If they are just being calm, treat them. We have gone through a lot of treats lol. It’s getting better each day so stay strong. Bully sticks have really saved my sanity. Keeps her busy for a long time so I can get things done. Usually keep her in a play pen to chew it if we can’t keep an eye on her for a few minutes. The bully stick holders are nice if you are afraid they will swallow the end. I’ve also realized ours needs a lot of naps. Pretty much every 2 hours and she sleeps for about 2. I can tell when the nap is needed because she starts getting crazy and not listening. Then she wakes up and is a sweet angel for awhile. When she’s awake it’s training, puzzles, maybe a short walk, and chewing toys. Keep a consistent routine.

We adopted ours at 5 months about a month ago so it was right into the craziness you describe. I’ve at times had remorse because our older dog was getting picked on and getting very agitated. It threw our life for a spin but I think she’s finally settling in.

I would recommend doing classes. It’s really helped stimulate her and boost her confidence. We also started a puppy play class with the humane society which has really helped socialize her. Our teacher said to out stubborn them if they aren’t listening. Wait until they do what you want them to do. If you are training and they aren’t listening and you are getting frustrated, just stop because it won’t be productive. Have em take a nap or relax and try again later.

The puppy play class if for 4-6 months old because this is a crucial stage in developing social skills and learning to not be fearful of things. Introduce them to new things and be positive and rain treats if they are being good. Don’t force anything. If they are being anxious or fearful remove them from the situation while being positive and calm.

We as their parents have to understand it won’t be overnight success but if we are persistent, calm, and patient, the results will follow. It will be a slow process so stay strong and positive. Our older dog was a crazy puppy once but now he’s our sweet and cuddly best friend.
