There are tons of things pet owners can do to make sure their dogs are happy and healthy, but one of the most important is feeding them nutritious and delicious foods.

While there are great wet and dry foods made especially for our canine pals, dog owners might not be aware that there are many human foods they're allowed to eat. On the other hand, there are several human foods that should never be ingested by dogs because it can quickly lead to life-altering results. These are the human foods that are both okay and off-limits for dogs.

One of the foods that should never be kept near dogs is chocolate. This sweet treat may be a pleasant dessert for humans, but Healthline admitted that chocolate contains theobromine and caffeine. Dogs cannot metabolize those chemicals and will experience dire symptoms if they do.

The symptoms can include vomiting, dehydration, internal bleeding, muscle tremors, seizures, and in the worst-case scenario it can end their life. There are some varieties that will do more damage such as cocoa powder and unsweetened baker's chocolate because they are more concentrated.

Similar to humans, dogs can also experience upset stomachs, especially if they are eating the wrong foods or if there is a drastic change in their diet. A human food that can aid an upset stomach for dogs is cooked white rice.

After they digest the bland white rice dogs' stool will firm up and give them the nourishment they may be missing out on from their normal food. The carbohydrates from the rice also provide a good source of energy, especially for older dogs. Make sure to not mix this up with brown rice because it has a higher glycemic index, which causes blood sugar to rise.

There are a lot of mixed opinions on whether or not dogs are allowed to eat avocado, but more credible sources urge owners to keep it out of their dogs' diets. The most common reason experts tell people to not give their dogs avocado is that it contains a fungicidal toxin called persin.

Persin is all over the different parts of the avocado and can cause vomiting, blockage in the heart, and even end their lives. The high amount of fat in avocado is also detrimental because it can upset their stomach, pancreas, and cause weight gain.

Dogs cannot tolerate eating lemons or limes. The skins of these citrus fruits include a substance called psoralen. Eating just small amounts of psoralen can cause vomiting and gastrointestinal issues, but the more serious symptoms come if larger amounts are ingested. These can include muscle tremors, difficulty walking, liver failure, and fatality.

Purina claims that when a dog eats something poisonous it will taste bitter because that's how they used to survive before they were domesticated. Dogs may continue to eat lemons because they aren't necessarily turned off by the sour taste.

According to the Kuakini Medical Center, about 90 percent of Americans consume caffeine daily. It can be found in coffee, tea, soda, medication, and more and is one of the most dangerous threats for dogs.

The best thing to do if your dog ingests caffeine is to contact a veterinarian who can advise which medication will help them ease their specific symptoms.
