my dog has several tumors after feeding him K-mart brand senior dog food (Champion). I found that it was taken off the shelves. since then, i\’ve been aternating feeding him Organix, Newman\’s, wellness (salmon), Diamond\’ & V-Dog. i\’ve been giving him supplements of Irish moss, powdered parsley, kelp, nutritional yeast, garlic granules, turmeric, bromelaine, glucosamine, chomdroitin, MSM, calcium citrate, olivr oil, & cayenne pepper on his food with water. He likes it and is satisfied after eating (he is a large, 10-yr-old lab/ Rhodesian ridgeback mix with slipped disk & a big appetite, & tends to gain weight easily). I also give him a cod-liver-oil cap each day. Hopopefully he won\’t develop cancer. (My daughter just lost her 2nd Rottie to cancer feeding them Costco kibble.) I\’m going to put him on a vegetarian food but not sure which brand is best. He\’s currently on the Wellness salmon kibble. I once had a puppy I raisd as a vegetarian. He was very healthy. but he didn\’t grow as big as his siblings. and had a rougher, darker coat but I atributed it to his being a mutt with maybe GHD genes. Also had a large Weimeraner that was fed a raw egg every day by my mom who thought it was good for her coat, but she developed a biotin deficiency (leg tremor), so I do not recommend raw egg white.
