My guy is just over a year old and had been eating Fromms Beef Frittata since he was 4 months old. Changing him to good food was really helpful (thanks EBN), especially keeping him from being all smelly and having to be bathed every other week. But he still had watery eyes and would get pink chin, face and paws as the day progressed and this while taking 2 benadryls twice a day. Then his chin started getting sores and the nose rope was all red and sometimes gunky no matter what wipes, pads or creams I used. Enough! I started researching recipes for treats and now make my own - grain free. His face started getting better but still yeasty. Again I sent out my SOS to EBN and was directed to Natures Variety Instinct. I found out it is Tapioca based instead of potatoes so it helps with yeast problems. The salmon flavor even notes on the bag that its great for allergies and like Fromms the flavors can be switched without tummy issues. We have one more week until he is fully transitioned but his eyes no longer run, he doesn't need the benadryl , and his face and paws are no longer red come evening. Yah! While all dogs respond differently to different foods, I suggest looking into NVI but also examine what other foods your baby might get like treats, bites and licks of people food, chew sticks, etc... Only by process of elimination can you determine the causes of the problem. Good luck!
