While you may love Fritos, they are certainly not the best snack choice for your dog. Fortunately, Fritos are not toxic to dogs, but they should not be regularly enjoying this human snack food.

Fritos come in many different flavors, in this article we will be discussing Original Fritos.

Read on to learn more about how Fritos affect your dog, whether they’re harmful, and whether you should worry if your dog eats any.

Ingredients in Fritos

One of the quickest ways to realize that Fritos are not a suitable snack for your dog is to look at their ingredients list. The three main ingredients in Fritos are:

Corn oil
Processed corn
Salt

None of these ingredients is nutritionally beneficial for your dog. They can actually be detrimental to your pup’s health, especially when consumed in large amounts.

Corn Oil

While dogs do benefit from healthy oils such as fish oils, corn oils could cause multiple issues in your dog if consumed frequently. Corn oil is rich in omega 6 fatty acids which if not combined with omega 3 oils can increase inflammation in the body. The high calorie content of corn chips can also lead to weight gain.

Processed Corn

While the use of corn is widespread in dog food, that doesn’t mean corn chips are good for your dog, especially when the corn is processed so heavily.

Salt

When it comes to ingredients of Fritos that are harmful to your dog, one ingredient that stands out the most is salt. Consuming large amounts of salt is dangerous for your dog. Dogs that eat excessive salt experience extended frequent thirst and eventually salt poisoning, which is why it is one of the foods you should never give your dog. If your dog gets salt poisoning, it could display the following signs:

Diarrhea
Vomiting
Seizures
Lethargy
Lack of appetite
Tremors
Excessive thirst
Excessive urination
Coma

How Bad Are Fritos for Your Dog?

Based on the information about the ingredients of Fritos, you probably understand that they’re unhealthy for your dog. Original Fritos don’t contain outright harmful ingredients for your dog, but they have high sodium levels, and they don’t provide any nutritional benefits.

That said, Original Fritos are not toxic to dogs. But giving your pooch Fritos regularly is certainly not recommended.

Final Words

Overall, dogs can eat a Frito or two without any serious consequences, but just because they can do it, doesn’t mean they should. There’s no reason to panic if your dog got into your Fritos stash, but it won’t have any nutritional benefit and they may get an upset stomach. Call your veterinarian if you have any concerns.
