In using the canine nutritionists' advice that I respect the most, I wouldn't feed any foods that are not biologically appropriate for the canine species:
Sugar (including lactate and glucose containing fluids). Sugar promotes cancer (Colorado State Univ. Vet Med diet study, 1997), damages the pancreas, drains vitamins and minerals blocking absorption, and is implicated in hypoglycemia, diabetes, obesity, behavior problems, cataracts, tooth decay, arthritis, allergies and yeast infections.
Sugar foods include processed foods, grains, dairy, many fruits and vegetables (including carrots and sweet potatoes) and many liquid glucosamine products high in fructose.
Chocolate - it contains theobromine which is a toxin for canines - plus caffeine (nerve irritant) and sugar.
Dairy products - unless from raw sources. Dairy contains foreign hormones and lactose (sugar) and is mucous forming in dogs. Mosts dogs lack the enzyme required to digest lactose and will often get loose stool or upset stomach.
Grain - no biologic need for grain exists in dogs and a poor energy source for canines (fat is best and the only source fully utilized by canines). Grains break down into sugar in the body and are also mucous forming in dogs often causing allergies, ear infections, skins issues, bloating, joint problems, and digestive disorders. High gluten grains are often the most problematic.
Raw Salmon - in the raw state, it contains a parasite fluke causing rickettsia - an infectious disease.
Yeast -Â we get rid of ants using yeast and sugar - as a tiny species, their imminent death shows the impact of these ingredients. These ingredients naturally expand in the body, causing bloat and their death. Yeast is a fungus and may cause a yeast overgrowth (gunky ears, itchy skin, licking feet and anal area etc.)Â It can seriously disrupt the calcium/phosphorus balance in the canine body.
Corn - a very common allergen in dogs, they assimilate this very poorly. Includes corn gluten meal and corn meal.
Raisins and Onions - toxic to dogs
Peanuts and Cashews - also contain toxic properties for dogs. Almonds and Almond butter a much healthier and safer choice for dogs.
