"DANGEROUS PEOPLE FOOD"
- Do not feed your pets:
Some foods dogs should not eat and could be deadly.
Grapes & Raisins - Grapes and raisins can cause kidney failure in dogs. As little as a single serving of raising can kill a dog.
Onions - Onions can destroy red blood cells and cause anemia.
Chocolate - Can cause seizures, coma, and death. Baker's chocolate is the most dangerous. A dog can consume milk chocolate and appear to be fine because it is not as concentrated, but it is still dangerous.
Coffee, Coffee grounds, Tea, & Tea Bags - Drinks/foods containing caffeine cause many of the same symptoms as chocolate causes.
Macadamia Nuts - Macadamia nuts can cause weakness, muscle tremors, and paralysis. Limit all other nuts as they are not good for dogs in general. Their high phosporous content is said to possibly lead to bladder stones. Exception to this rule is PEANUTS and PEANUT BUTTER. However, always use salt/sugar free peanut butter.
Peanut Butter - The sugar in peanut butter encourages cancer growth. Always use ORGANIC PEANUT BUTTER as regular peanut butter contains a lot of toxins.
Animal Fat & 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 arythemias. Tomato plants are the most toxic, but tomatoes themselves are also unsafe.
Avacados - The fruit, pit, and plant are all toxic. They can cause difficulty breathing and fluid accumulation in the chest, abdomen and heart.
Nutmeg - Nutmeg can cause tremors, seizures and death.
Apples, Cherries, Peaches and similar fruit - The seeds of these fruit contain cyanide, which is poisonous to dogs as well as humans. Unlike humans, dogs do not know to stop eating at the core/pit and easily ingest them. It also becomes lodged in the intestines and kills the dog 24 hours with no warning.
Raw Eggs - Raw eggs can cause salmenolla poisoning in dogs. Dogs have a shorter digestive tract than humans and are not as likely to suffer from food poisoning, but it's still possible.
Salt - Excessive salt intake can cause kidney problems.
FOOD THAT 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 dog should be avoided. Like people, some dogs cannot tolerate certain foods.
Meats - Meats should be boneless and it's best if the skin is removed. Raw meat is NOT a good idea because of the risk of food poisoning and parasites.
Boneless Skinless Chicken Breast
Boneless Skinless Turkey Breast
Fish - DO NOT FEED TUNA! It has a high mercury content. be careful of small bones. (This goes for cats as well)
Vegetables - 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. The best veggies for your dog are:
Carrots - For healthy dogs. Do not give carrots to dogs who have cancer because they do contain sugar.
Grains - Grains should not be given in large amounts or make up a large part of a dogs diet, but these foods are generally safe in small amounts, such as rice.
Dairy Products - Use caution with dairy products as they are high in fat and can cause pancreatitis, gas and diarrhea. Usually, nonfat, plain yogurt is safe in small amounts as is cottage cheese in small amounts.
