There are certain things that dog owners generally know are bad for their dogs — like chocolate and onions — but there are so many other foods that are toxic for pups that owners may be less aware of. There are a few important things your dog shouldn't eat under any circumstances — tons of fruits, veggies, spices, and random ingredients that seem totally harmless but can actually have extremely dangerous effects on your pup. What's healthy to humans can be fatal to dogs, and that's because our bodies break down foods differently. For instance, a plain salad can be incredibly nourishing for humans, but totally fatal for dogs — and that's because some of ingredients that are good for us aren't able to be processed by their bodies. That's why this information can be so shocking to dog owners.

When you have a dog that love table scraps, it can be hard to resist feeding them bits of your food. As someone who has a terrible track record for abstaining from giving a begging dog a treat from the table, I know just how hard it can be to say no when your pup gives you those cute eyes. That said, it's important to know what the most harmful foods for dogs are so that if you do want to give your pup table scraps, you know what you're giving them is healthy for them. While of course the amount of a food ingested in relation to a dog's particular size and weight will affect just how toxic any of these ingredients can be, it's best to avoid them all together for your dog's health. Here's what you should never feed your dog under any circumstances, no matter how big or small they are.
