I have a 9 year old maltese/yorkie mix with an extremely sensitive stomach, plus acid reflux. She has been through dozens of different dog foods, always trying to find one with quality ingredients, that was right for her breed/size, and that was easy on her stomach. One time when she was having a lot of stomach issues, or vet suggested that we only feed her Eukanuba or Iams brand food. Well we took this advice to heart and put her on strictly Eukanuba for quite a long time, and it seemed to really help. Eukanuba seems to have quality ingredients and it is a trusted brand. I am a little picky about what we feed her, just because I don't want her to be feeling bad or sick, and she had excellent results with this brand. My dog enjoyed eating this brand, was able to maintain her weight without any stomach issues. I trust Eukanuba for having a quality product. Quality of Ingredients Eukanuba dog food has really excellent ingredients. I feel that it is one of the brands that has minimal preservatives and processed junk in it, that we shouldn't be feeding our canine family members.
