Everyone knows not to give their dog chocolate. It's pretty much common knowledge that the sweet stuff will make your dog dangerously ill.

But there is a myriad of other foods that need to stay far away from your dog, and many of them people probably don't know about.

While it's never really a great idea to feed your dog "people" food, there are certain items that can be okay. Chicken, beef, salmon and peanut butter are all canine favorites that are safe for them to eat.

Scroll through this list and see which foods can be quite dangerous if you feed them to your dog.

1. Alcohol (obviously)

This seems super obvious, but even the tiniest amount of alcohol can send your dog into a coma, or even kill them.

2. Avocado

Avocados contain persin, which is toxic to dogs. It can cause stomach problems, vomiting, and diarrhea.

3. Caffeine

Caffeine can cause vomiting and diarrhea in dogs. More seriously, it is toxic to the heart and nervous system.

4. Grapes and Raisins

It's not really known WHAT about grapes and raisins makes dogs sick, but there is documented evidence proving they can cause acute kidney failure.

5. Macadamia Nuts

Macadamia nuts can cause rear-leg weakness, low-grade fever, and muscle damage.

6. Garlic and Onions

Both onions and garlic can give your dog blood cell damage and cause anemia.

7. Milk

Dogs are basically lactose intolerant. Too much dairy can mean severe diarrhea.

8. Mushrooms

Many types of mushrooms are toxic to your dog, and can even cause death. The danger is heightened because of how often dogs are outdoors, so it's always recommended to keep an eye on what your dog is eating.

9. Xylitol

Xylitol is found in a lot of chewing gums, sugar-free Jell-O, Tic Tacs and even some brands of peanut butter. The ingredient can cause liver failure and death in dogs. Make sure you are checking any new brands of peanut butter for xylitol.
