I second the Yak chews. My puppy absolutely loves them and will chew them for hours. He hasn't even finished the first piece we gave him and that was at least a week ago. They are pretty expensive but in my opinion, totally worth it. They have different sizes depending on your dogs weight.
I found them at my local dog store but they are on amazon as well. https://www.amazon.com/dp/B004GT6J0Q/ref=cm_sw_r_cp_api_32MEybJD2NCN6)

New babies are intense whether they are human babies or dog babies. Remember when your 3 old was a newborn? I bet he required a lot at first too. It sounds like you have a young, high energy dog who is doing what comes naturally to them. Not all dogs need the same amount of exercise. A tired dog is a well behaved one, especially if she's young, and the constant kenneling will drive them crazy with excess boredom and energy. I recommend trips to the local dog park at least once a day every day plus two long walks a day. Train only when your dog is tired and able to listen. There are couple of chew toys that are nearly impossible for dogs to pass up:
Himalayan Yak Chews smoked, hard cheese chews which dogs will usually run off with and chew for hours
Smoked or roasted marrow bones these last forever and keep dogs occupied with the meaty bits on the outside and then with getting the tasty marrow out of the bone. When the bone is empty, you can refill with peanut butter and kibble
Smoked pigs ears - they won't last long, but they're irresistible and cheap
The Kong - a must have for dog owners. Get 2 so you can always have a full one ready. Fill with high value treats like hot dogs and yogurt or whatever your dog likes. There are lots of recipes online. Freeze to make it harder to get the stuffing out. My trainer recommended that I feed half my dog's dinner in the bowl and give the other half in the Kong to work their minds because wearing out a dog isn't just wearing out their body. You have to wear out their brain too.
Take your dog to a training class and spend the time bonding with her. Play games like "What's my name" where you teach her her name by calling her name and giving her a treat when she responds to it or "Ping Pong Puppy" which requires a helper. You start with holding the dog and have the other person call the dog. When the dog goes to the person, she gets a treat. You call the dog back, give her a treat, the other person calls, treat and so on. Leave her leash on when she's out of her kennel and have her follow you around the house. Eventually you can drop the leash and she'll follow you anyway.
Finally, stop and ask you dog what she needs. She's trying to tell you something and you're not receiving the message clearing. Sit down, get on her level in a moment when no one else is around and it's quiet and try communicating with you dog. Ask her what she wants and needs. Then LISTEN. She'll let you know. Dogs understand and communicate at roughly the same level as a human toddler, but they can't speak English so you have to learn to read their body language and interpret their language. What would you do if your 3 year old only spoke sign language in Greek? Same idea. I hope things work out for you. I'd hate to see another dog end up in the shelter.
Try Himalayan dog chews. You can get them on Amazon and I’ve seen them at petsmart. They come in soft - hard so you can choose what works best for your dog.
Sounds like a similar philosophy as us. She gets toys occasionally but almost always immediately destroys them. Luckily, she still loves flinging them around (very similar to this, but in the house).
Otherwise she regularly gets these Himalayan dog chews and elk antlers to chew on. She has almost chewed up all of the last antler we bought her so it is probably time for a restock.
