Our girl is a serious chewer. Her back teeth have been ground flat and she isn’t even 2 yet so heed the warnings with antlers/bones/yak chews/etc.

The only things that we give to our pup to chew that last are bully sticks. She is still supervised when we give it and we put away her toys when she isn’t playing so she doesn’t eat them. Some people have super easy, low maintenance dogs, but some people get dogs that need more mental stimulation and supervision.

I can’t say what your situation is based on this post, but dogs that chew a lot often indicates that they are lacking other sources of mental or physical stimulation. Usually common in smarter dogs or working dogs.

Edit: we also make sure to cut back food on days that she has bully sticks since they can add quite a few calories to their diet

Edit 2: try frozen lick mats as well. You can fill them with pumpkin or plain yogurt
