Our veterinary gave us a paper about the real scoop on pet foods. He talked about by products as being an inexpensive way to increase the protein content of the food. The sheet reads avoiding anything with by products in it. By products can contain feet, feathers, skin, intestines lung, brain, bone or blood.The fillers like ground corn, wheat middlings, wheat & corn glutens, sorghum etc. can cause dogs to develop allergies to these ingredients. He mainly pointed out protein as the first ingredient on the bag label with a source of carbohydrates as the second ingredient like rice or potato. At the vets office they favor Canidae/Felidae, California Natural, & EVO pet foods. I didn't get a chance to read any labels because I had Baxter with me at the time. I plan to visit the vets office to look at what they have, there are two co-ops that sell dog food. I plan to spend some time going around reading labels. I was given 5 sample bags to take home & Baxter liked the food he has never been a picky eater. The itching has stopped for now.
