Human Foods That Can Harm Your Pets: What to Avoid

As pet owners, we want the best for our furry companions, but sometimes our well-intentioned gestures of sharing food with them can have unforeseen consequences. Are the snacks you offer your pets really safe? The truth is, some human foods are toxic to pets and can result in serious health issues or even death.

Human Foods to Avoid for Dogs

Chocolate

Chocolate contains theobromine and caffeine, stimulants that are dangerous for dogs. These cause symptoms like vomiting, diarrhea, rapid breathing, irregular heartbeats, tremors, and seizures. Severe toxicity can lead to coma or death, especially from dark or baking chocolate, which has higher theobromine levels.

Grapes and Raisins

Even small quantities of grapes or raisins can lead to acute kidney failure in dogs. The exact toxin remains unidentified, but symptoms like vomiting, lethargy, loss of appetite, and abdominal pain can be severe. Although sensitivity varies among dogs, it is best to avoid feeding grapes and raisins altogether.

Onions and Garlic

Both onions and garlic, whether raw, cooked, or powdered, contain thiosulfates, which can cause oxidative damage to red blood cells. This can lead to anemia, a condition where the body doesn’t have enough healthy red blood cells to carry oxygen. Symptoms of onion and garlic toxicity include weakness, lethargy, and decreased appetite. Even small quantities can be harmful, so it’s essential to keep them away from dogs entirely.

Xylitol (Artificial Sweetener)

Xylitol, found in sugar-free gum, candies, baked goods, and some peanut butters, is highly toxic to dogs. It causes a rapid insulin release, leading to hypoglycemia, with symptoms like lethargy, loss of coordination, seizures, and possible liver failure. Dogs that have ingested xylitol need immediate veterinary care.

Avocados

Avocados contain a fatty acid called persin, which is believed to cause vomiting and diarrhea in dogs. It’s less dangerous for dogs than for some other species, but it’s still best to avoid feeding them avocado in any form. The pit is also a choking hazard and can lead to intestinal blockages if ingested.

Alcohol

Alcohol is poisonous to dogs and can produce a range of symptoms from vomiting, diarrhoea, difficulty in breathing, coma, and even death. Alcoholic drinks, foods containing alcohol, and even some uncooked doughs should be kept away from dogs. Dogs are more sensitive to alcohol than humans, and only a small amount can be dangerous.

Cooked Bones

Although raw bones may be okay for some dogs, never give a dog cooked bones. Bones become brittle when they are cooked, and can break into sharp shards that can cause serious injury, including but not limited to puncturing the dog’s mouth, throat, stomach, and intestines. Their signature three feet of intestine can be wrapped around a pointy shard. Stick to dog-specific bones.

Salt

Overconsumption of salt can cause sodium ion poisoning in dogs. Symptoms include vomiting, diarrhea, tremors, seizures, and, in severe cases, kidney damage. Do not leave processed, chippy, or high-salt foods within reach of dogs.

Nutmeg

Nutmeg contains myristicin, a substance found in nutmeg, which can lead to hallucinations and even seizures, as well as organ failure if you give it to your pet. Although dogs are unlikely to eat nutmeg on its own, they could ingest it as part of a baked good or meal that contains it. It can be very toxic if taken in high doses.

Human Foods to Avoid for Cats

Chocolate

Just like with dogs, it’s important to remember that chocolate can be harmful to cats, too. Theobromine and caffeine, which are present in chocolate, might lead to issues like vomiting, diarrhea, rapid breathing, and seizures in our feline friends. Even though cats are less likely to munch on chocolate compared to dogs, it’s always a good idea to keep it safely out of their reach. Dark chocolate, in particular, is more dangerous because it contains a higher amount of theobromine.

Onions and Garlic

Onions and garlic are the most toxic foods for cats because they contain substances that damage red blood cells, leading to hemolytic anemia. Cats are susceptible to this poisoning, and even small amounts of onions can cause symptoms such as lethargy, weakness, and loss of appetite. Whether fresh, cooked, or powdered, these foods should never be given to cats.

Dairy Products

Contrary to common belief, most cats have lactose intolerance and do not view milk as a treat. They do not properly digest lactose, a sugar in milk, which can cause gastrointestinal issues such as diarrhea, vomiting, and bloating when dairy is given to a lactose-intolerant cat.

Grapes and raisins

While there is less risk for cats than for dogs to consume grapes and raisins, it is still hazardous for cats, even in small amounts, because it can lead to kidney failure. It’s best to avoid giving these fruits to your cat altogether.

Alcohol 

Alcohol is toxic to cats, and even a small amount can be poisonous. Some of the symptoms range from vomiting to lethargy to difficulty in breathing, or even more serious conditions like coma or death. Keep all beverages and foods containing alcohol out of reach of your cat to avoid any accidental ingestion. 

Raw fish 

Raw fish, especially salmon, may contain parasites that are harmful to cats. Besides, it includes an enzyme called thiaminase, which destroys thiamine (vitamin B1), leading to its deficiency and neurological problems. Some fish can be given to a cat in moderation, but it is always best to cook fish well before giving it to your cat.

Caffeine

Caffeine is poisonous to cats, and even tiny amounts can be fatal, triggering rapid breathing as well as heart palpitations and tremors. A stimulant effect of caffeine can potentially have fatal results for cats. 

Cooked Bones

Cooked bones are as bad for cats as they are for dogs. They can also splinter and pose choking hazards, or cause internal injuries or obstructions in the digestive system. Never feed your cat cooked bones, and be very cautious when giving them raw bones.

Raw Eggs

Raw eggs can harbor bacteria such as Salmonella or E. coli, which can cause food poisoning in cats. Raw eggs also contain a protein called avidin, which can prevent the absorption of biotin (a B vitamin), leading to skin and coat problems. It’s better to be on the safe side and not feed your cat raw eggs.
