- Nylabone Teething Keys: A firm fave at the ZigZag HQ. They look like actual baby teethers...if having a fur baby is your thing. - Buffalo Horn: These are made from keratin, so they’re gentler on teeth than bone or antler. But they also last a long time, and you can also stuff the hollow ones with food. - Yak Chews: Made from Himalayan Yak Milk, these are a hit for most puppies. - Ice Bone: These are great for sticking into the freezer for glorious days of soothing sore gums.
