It's totally fine for you to feed your dog veggies as part of a well balanced diet. Please do keep in mind though, that for a totally healthy dog, you will have to feed it meat protien, as that's just part of who they are. People can take vitamins to suppliment our diets, dog's are more difficult to judge.

Here is a general list of foods (as found by a general "Google"):

Some foods dogs should not eat

If your dog has ingested any of these foods, get veterinary help immediately
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.
Chocolate: 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 and tea bags: Drinks/foods containing caffeine cause many of the same symptoms chocolate causes
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. (it should say: cooked bones)
Tomatoes: Tomatoes can cause tremors and heart arrhythmias. Tomatoe plants and the most toxic, but tomatoes themselves are also unsafe.
Avocados: 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 fruits 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.
Raw eggs: Raw eggs can cause salmonella poisoning in dogs. Dogs have a shorter digestive tract than humans and are not as likely to suffer from food poisoning, but it is still possible.
Salt: Excessive salt intake can cause kidney problems.

I hope this helps!
