Orijen. Check chewy.com for reviews. Or, Nutrisca for a limited ingredient food…I actually mix the two for one of my dogs, with good results.
Don’t free feed, feed twice a day, measured amounts. Pick up and store in the fridg if not eaten within 10 minutes and offer at the next mealtime.

Are you sure you are not overfeeding? Try smaller amounts. Sometimes, less is more.
Add a splash of water to the kibble. Most dogs don’t drink enough water.
