Hi Melissa,
TOTW is one of Diamond’s house brand’s of food. If you aren’t familiar with Diamond, they’re a sketchy company with a reputation for cutting corners and recalls. I don’t believe we’ll ever see any Diamond products on the Editor’s Choice list.
It could be that the probiotic formula change is the cause; but like Marie, I would tend to think it unlikely that you got a hold of product that has just been manufactured.
Ruling out environmental allergies is tricky. It could be something like laundry detergent, Febreze or new flooring, but could also be something seasonal like ragweed or leaf mould. Steroids are just a bandaid and mask symptoms, and can cause plenty of problems themselves. I’d definitely avoid further steroids use if at all possible.
Even if the problem isn’t food related, three years is an awfully long time to be on the same food. I rotate every bag of kibble I feed. I buy different brands with different proteins and binders. Subtle ingredient changes don’t generally affect my dogs because they’re used to switching. One of my dogs has food intolerance issues, so it’s hard to find things he can eat, but I’ve found a few that are good quality, that he likes and does well on.
So while it may or may not solve their immediate problem, a food change could prove beneficial to their overall health.
