I wouldn’t worry at the moment. It’s a small handful of dogs affected and there is still so little understood about what is happening to these few dogs.
If you are seriously concerned schedule and echo of your dogs heart and send findings to the fda so they have more info to go on. The fda is suggesting to not switch foods as it is of little concern right now. Some of the foods these affected dogs were eating included purina, hills, and other big brands with grains as well.

This article gives a non bias view of the issue at hand.
Bottom line, don’t switch. Have an echo done if you’re seriously concerned. Report findings and go from there
