Throwing Up
I had such a problem with this not too long ago. My baby Fenway is now 13 months old and we seem to be in the clear. I tried everything from the rice and low fat cottage cheese diet to switching foods a total of 5 times. The vet didn't seem to know what to do (I have since switched due to frustration). I did however, switch his food to brightlife at around 8 months old and the throwing up seemed to stop almost immediately. I also give him the raw advantage (small ground up chicken, carrots, among other things which are supposed to help with settling their stomach) and he loves them. One thing my vet never offered was the skin allergy test. I heard that they do it just like they do on humans. I was never officially told, but believe that he is allergic to both the wheat and corn and this food I am recomending is an allergy food and not too expensive. The Nutro seemed to make it worse for my baby. Just too rich and then mixed with the allergies.
Hope this helps a bit!
