Puppybone

Puppybone is made from inert thermopolymer to which calcium has
been added during the moulding process. Puppybone is strong and
durable but the addition of the calcium, being a natural material,
makes the product a little softer than Gumabone and is thus
suitable for use by very young dogs whose jaws and adult teeth are
still developing. Choose the largest size that your puppy can
comfortably carry in his mouth and remember that as he grows he
will need to progress to a larger chew device.
