Canine Grain Free Food

Thanks for all the replies. Yes, of course, I have been feeding less food! She is eating a measured amount. It is not left for her to eat freely. For those asking why grainfree....over a year ago, my Aussie went thru a period of bilious vomiting. This would occur early in the morning waking us up and causing her distress. After much research, I learned that this was common in deep chested breeds and caused by too much stomach acid being produced. Also, I read that dividing up food into 3 meals with last feeding in the evening would help. Grainfree food with low fiber and fat is recommended. She was eating Nutro Chicken at that time. She started on Diamond Puppy as recommended by her breeder. The stomach issues have ended. Seems to me that the 3X feeding grainfree has been the fix. I merely do not want to have a future overweight Aussie. She is happy, healthy and active weighing about 42# at 4 years old. I guess dog food & diet may be a sore subject here. Thanks to xteacher for answering my question with reduced fat grainfree Wellness Core!
