Honestly I don’t think any of those have anything to do with itAlso, there seems to be 3 main things that the DCM cases seem to have in common.
- The dogs were fed the same kibble every single day, for every single meal. No rotating through other brands.
- They were fed, sometime drastically, under the recommended feeding guidelines on the bag.
- They were were fed very little, or none at all, fresh animal proteins, eg meat/offal/fish/eggs etc
