I studied ingredient lists in kibble for a long time and could not find one that satisfied me. Besides pet food company regulations about what they have to list in the ingredient list are very lax to non existent.
Gracie refused all kibble anyway so we ended up feeding Stella & Chewy's freeze dried food and the frozen kind as well. I was well satisfied about the quality ingredients. I also sometimes prepare her food at home. She has done very well with this type of feeding. Fresh foods are always healthier than ones with preservatives and synthetic vitamins added to replace what processing has taken out.
