Because this is a natural product, you may notice fat at the bottom of the packet. This is normal and will not cause any harm to your pet but as stated on the packaging, please treat on a non-stainable surface. Choose an appropriately sized treat for your dog. Keep an eye on them while they're feeding, as natural products may splinter and cause injury. Always give treats on a non-stainable surface. To avoid the danger of suffocation, please keep bags away from babies, small children and pets.
