We do not recommend giving puppies marrow bones, or antlers until they have lost all their ‘puppy teeth’ and have their permanent adult teeth. For teething puppies, we recommend filling and freezing their favorite rubber toys with a mix of our Toppers & Hydrators, and some of their favorite foods. This can soothe their need to chew, keep them busy, and provide enrichment. As always please monitor your pet with any toy or treat.
