I know as well as anyone to avoid products (especially pet foods) that are made anywhere but in the U.S.A., but after several months of giving these to our senior rescue Foster - a big
for these sweet potato "chews".
Dr-Chew®, the original
Before ordering, I initially called and spoke with Knine Kountry (Tracy). She told me they have been selling these for more than 3 years with NO issues or complaints. Due to the history of tainted pet foods, apparently Dr-Chew distributors have instituted VERY stringent quality controls. She even offered a personal reference - her mother, who she claims is EXTREMELY picky and careful about what her dogs eat.

I even checked out the Landy Corporation (couldn't find anything suspicious or scary online about them), website under construction,
they have a patent pending on the chews. Also did a cursory search on the distributor, Windmill Distribution:

The chews are also recommended by the Whole Dog Journal.
Foster has a tendency for bouts of colitis, so bully sticks (as much as he loves them, eeeugh) -- even 1/3 of one, make him sick. These chews have become a substitute, SUPER anticipated treat for him. No problems to date. Granted, even the large ones do NOT last anywhere near as long as a bully stick...but has done well with them....nutritious, good for his teeth, and he LOVES them. A big plus is the "no blockage" label.
We just recently ordered a case, to stay well-supplied. There are several sources online.
