Dental enzyme and trachea collapse

I wrote recently about my little dog's close call with dental enzyme dog chews and how she nearly died while using them.  I mentioned CET enzyme toothpaste, because it's working so well is what gave me the idea to try the dental enzyme chews.  Well, I went back and checked all the dental enzyme rawhide chew packages for the brands I had been using, and all of them were made outside the USA.  I checked the CET toothpaste and it is made IN the USA.  It really does work so much better than regular doggie dentifrice toothpaste (usually some kind of scrubbing granule and not as effective for me, since I only brush the dogs' teeth once a week - a chore, but it beats having them go under anesthesia to get their teeth cleaned).  I am going to trust the USA-made product and keep using VirBac CET dental enzyme toothpaste.  At least, I'm going to do so and monitor my dogs' trachea problems (hoarse, cough, etc.).  I'm going to check the (more expensive) CET dental enzyme rawhide chews to see where they're made, but I'm leary of chews now.  Definitely, no more Petrodex or Dentley's dental enzyme chews - NOT made in the USA, darn near killed my dog.

I also use Virbac dental enzyme toothpaste for my dog. The one available here (UK) is manufactured in Germany. I am hoping it's OK....
