My girls LOVE, LOVE, LOVE the bully sticks from AMD. She sells them on her website.
My girls also love the
chew bones from Healthy Pet Net.
I sell those on my website. They are all pork so are completely digestible...no rawhide.
I also give my girls those hard rubber toys for puppies as they are pretty indestructible. It is very important that they chew when they are teething so they can get those baby teeth out! If they don't, you will need to have the baby teeth removed when you get your baby spayed/neutered.
As with any treat or chewie, always supervise and remove when the item gets small enough to swallow. You don't want your baby to get choked.
