Grapes and Raisins: Grapes and raisins can cause kidney failure in dogs. As little as a single serving of raisins can kill a dog
Onions: Onions destroy red blood cells and can cause anemia.

Macadamia Nuts: Macadamia nuts can cause weakness, muscle tremor and paralysis.
Animal fat and fried foods: Excessive fat can cause pancreatitis.
Bones: Bones can splinter and damage a dog’s internal organs.
Tomatoes: Tomatoes can cause tremors and heart arrhythmias. Tomatoe plants and the most toxic, but tomatoes themselves are also unsafe.

Salt: Excessive salt intake can cause kidney problems.
Food that most dogs can eat:
Some “human” foods are good for dogs. Most of these are healthier than the boxed treats you buy in the grocery store. . This is just a small list of examples of foods dogs can eat, not a list of every food they should eat. Dogs won’t necessarily get all the nutrients they need if they eat these foods exclusively, so check with your veterinarian if you are interested in feeding your dog a home cooked diet.
Any food that causes stomach upsets or digestive problems in your dogs should be avoided. Like people, some dogs cannot tolerate certain foods even if they are considered "safe".
Meats should be boneless and it’s best if the skin is removed. A raw meat is not considerable as a good idea because of the small risk of food poisoning and parasites.
Skinless, boneless chicken breast
Skinless, boneless turkey breast
Dogs have shorter digestive tracts than humans and cannot digest most vegetables whole or in large chunks. It’s best to put them through a food processor before giving them to your dog
Red and green bell peppers
Grains should not be given in large amounts or make up a large part of a dog’s diet, but these foods are generally safe in small amounts
Use caution with dairy products as they are high in fat and can cause pancreatic, gas and diarrhea. Usually, nonfat plain yogurt is safe in small amounts
