I want to warn all Shih Tzu owners about using rawhide bones! I have a 1 y.o. female Shih Tzu named Bella & app. 2 weeks ago almost lost her-due to a knotted end from a small rawhide bone getting stuck over her windpipe! I tried to remove it from her throat & couldn't, although the Vet said that I actually pushed it futher back into her throat & that opened up a small area on her windpipe...just enough to allow some air in & gave me time to rush her to the Vet. I have had a dog(s) my entire life & never thought something like this could happen.
I have had nothing but problems when I give my shih tzus any kind of raw hide. They chew it until it breaks of then it gets stuck in their throat causing them to throw up. I have sooo many raw hides to give away because I am scared something like your situation might happen to one of my dogs. I am glad it worked out for your dog.
