Hi there, I just got my yorkie Sadie on the 14th of August. She is wonderful, starting to understand potty training and has learned how to sit

I am teaching her 'shake' and other paw.
She sleeps through the night and I couldn't be happier with her! I am feeding her Puppy Gold by Fromm which is one of the best foods to feed dogs. I am wondering what I can give her for a chew treat. I have little treats by Fromm and Zukes but I want something that she can chew on. A friend gave her a rawhide when I was gone which I know is very bad for them so for now I just let her lick it and not chew any pieces off. I will be heading to the local Bark and Fitz to find something soft that will take her a while to chew but I wanted to ask if anybody had any ideas of something all natural/organic with no chemicals or anything that I could give to her?
Thanks so much!!
