As a follow-up, in the end we learned that there were only certain lots of food (very narrow date range) that were responsible for making animals sick. Thus the customer who had no problems likely did not have a bag from the affected lot. Timberwolf did pay for the majority of my customer's vet bill, however they were afraid to ever put their dogs back on the food.

My other customers continued to use the food and their dogs thrived, however the price increase made it impossible for them to continue using it. I have one remaining customer, her dog has severe allergies, and they had gone through so much with that dog, that they will never change from the Timberwolf Bison as their dog is beautiful and thriving unlike during the previous years constantly at the vet, on one prescription after another, losing weight and most of her coat. This food has been a true blessing for them.

The food I rate 5 stars! The customer service I rate 2 stars. The price is just more than most can afford.
