I got Toki (10 months) the puppy nylabones a couple months ago and she just recently started gnawing big chunks out of the ends! She doesn't swallow them.... She just likes to roll on the loose chunks and toss them around. I bought some that were one size bigger and they are perfect so far! The chewing on that nylabone from your pup seems normal to me! I believe I read somewhere that the Nylabone material is not harmful if your pup swallows small bits but I'd move up a size if your pup is getting more aggressive with the chewing |
