I have fed Nutro Lrg. breed and senior L.B. for years. (I actually did dogfood demos for them for awhile). After comparing labels I switched over to a food at Wlamart...NO it wasn't Ol roy (BLECK!) anyway they have a food called Maxium Nutrition there (almost the exact same contents as nutro max) no by-products no corn, naturally preserved etc.The dogs coats looks great and their poo looks like it should. My female Dane has had a few health issues lately and I was checking into holistic foods for her. I decided to put Tisha on a newer food ( I guess)called Canine Caviar. It was actually created by someone that had a Dane with food allergies and they got sick of trying to find a food for their dog. The say their dane lived to be 17 years old. The food smells great, looks good, it is nice and crunchy for their teeth, plus the ingredients are great. It has antioxidents, omega 3 &6, no corn, wheat or soy. and it is holistic. I am using their special needs blend which says it is for senior and overweight dogs. Has anyone else used this and if so what do you think? I also found coupons on their site. LOL
