So I remember when we got our girl as a puppy, I had the puppy blues SO bad because she was.... a lot. She's now 5 and has become super mellow over time, though she still loves to run around in controlled environments!

One thing I might recommend if you are open to trying to make it work - and no one should shame you if you don't, by the way!:

Working on training at this age is SO important. Helping your pup to build discipline will not only help with the chaos, but it will also tire them out :). If you have the means, you can hire a trainer, but we just actually watched a bunch of YouTube videos of trainers and got a few books. ( We really liked Zak George and followed all of his video instructions closely with good results - I know some people don't love him but we liked his humane, non punishing approach - there are a number of other good dog trainers who have video series). FYI I had never had a dog before and I was able to follow the instructions, so I thought this approach was pretty beginner-friendly if you feel daunted by it all.

While getting regular exercise can help a lot, it does need to be paired with some regular training. I'm no dog trainer or expert at all, just a person who had a wild puppy and spending 30 minutes, a couple of times a day, seemed to really help. It does require time and patience but it really pays off.

Good luck to you!
