Personally never understood the concerns at all... A few years ago, one of the major medical schools in this country conducted a laboratory test to address the issue… The results showed that in groups of test dogs, even in those fed an almost exclusive diet of rawhide, there were no ill effects… On the other hand, chewing the rawhide had the beneficial effect of removing plaque and keeping teeth cleaner…. Which is significant because periodontal disease is a real problem in many adult dogs… I've been breeding for 30 years, and let my pups have rawhide sticks as soon as they start trying solid food. The thin little sticks are good for teething, 'cause they can get them back into all the little places that are hurting… and don't be concerned if you notice a little blood on them every once in a while when he's teething… it's just the teeth coming through under the pressure of him chewing… it's what's supposed to happen.
I have a shiba and he just past his chewing phase. All I can tell you is that if your puppy bites furniture get bitter apple spray. It doesn't hurt the dog just gives them a little bitter taste not to bite that every again (some dogs like the bitter apple spray test, mine didn't).As for the bones- I gave him porkhide bones because it's known to be a little bit better for puppies.Finally you have to have many chew toys for a shiba, KONGS help a lot, also ropes are good.Try to avoid stuffed toys because with sharp little shiba puppy teeth it's hard for then not to destroy them.The teething phase for a shiba inu usually ends at 7 to 8 months.Hope I have helped!
