The Worst 12 Human Foods For Your Dog

Twelve worst human foods for your dog Many of us like to spoil our dog with little luxuries and that can include sharing a tit-bit of our food from time to time, but some of our tasty human foods can be harmful or even fatal to your dog. Take a look at the foods listed here, many of them everyday household foods, and avoid feeding them to your dog.

Every year thousands of dogs visit the vet after ingesting foods which are harmful to them, often without the owner even realising what has caused the problem! If your dog has ingested any of these foods contact your vet immediately, as with most poisons, the sooner treatment is commenced, the better chance of a recovery from the effects of the poison.



Chocolate is poisonous to dogs


This is probably what every dog owner (and even some of our dog-less counterparts) knows. The same chemical that gives chocolate (especially dark chocolate) it's distinctive taste can be fatal to dogs.
And when we say fatal, we mean fatal, because there have been numerous dog fatalities due to chocolate.

Keep it away and do not give to your furry friend, no matter what. There are a lot of tasty alternatives to chocolate so maybe it’s time to find a healthier and even tastier substitute for chocolate.

Chocolate may not be toxic to your dog if given in very small amounts, however it is the most common cause of dog poisoning and can slowly accumulate it’s poison in the dog’s body due to digestion restrictions. Namely, cocoa beans contain caffeine and theobromine, a chemical compound. The dog isn’t able to metabolize theobromine as fast as humans and the more theobromine the chocolate contains, the more poisonous it is to your dog as this poison accumulates in your dog’s body.

The signs of chocolate poisoning are vomiting, diarrhea, seizures, tremors, high blood pressure, respiratory failure and even cardiac arrest.


Grapes are poisonous to dogs


This is a snack you may not expect to be dangerous for dogs. After all, it’s a fruit! But some dogs are especially sensitive to grapes (and raisins, which are dried grapes) and can suffer kidney damage from eating the sweet food.

The cultivation of the domesticated grape began 6,000–8,000 years ago in the Near East and fairly early on it was discovered that they should not be given to dogs.

The reason some dogs develop renal failure following ingestion of grapes and raisins is not known.

Types of grapes involved include both seedless and seeded, store bought and homegrown, and grape pressings from wineries. Their toxicity to dogs can cause the animal to develop acute renal failure (the sudden development of kidney failure) with anuria (a lack of urine production).

These are all serious health conditions and should not be taken lightly.

Be especially careful with grapes that have gone bad, because sometimes they will sniff them out of the trash bin and eat them, if not properly disposed. Since it is still not clear why some dogs can eat grapes and experience no health problems, while others become very ill after consuming only a few grapes, it is best not to include them in your furry friend’s diet.

Symptoms of grape poisoning include vomiting, diarrhea, weakness, dehydration, abdominal pain and lethargy within 12 hours of ingestion.

If your dog eats grapes and experiences any of these symptoms, instant treatment is necessary. The recommended treatment is to induce vomiting, but make sure to call your vet first for advice and assistance.


Onions and Garlic are poisonous to dogs


Allium sativum, commonly known as garlic, is a species in the onion family, Allium. Strangely enough, Allium is the substance that’s toxic to dogs.

With a history of human use of over 7,000 years, garlic is native to central Asia, and has long been a staple in the Mediterranean region, as well as a frequent seasoning in Asia, Africa, and Europe. Garlic has been used as both food and medicine in many cultures for thousands of years, dating at least as far back as when the Giza pyramids were built.

Although it’s rare for a dog to eat enough garlic or onions to hurt themselves (but the amount that causes poisoning can be dependent on the size of the dog), you should be aware of the possible dangers such as damaging their red blood cell production. Curries and some other foods of Asian origin can contain a high amount of onion or garlic.

Still it is far better to be safe than sorry, especially when it comes to the immune system of your beloved pet and avoid garlic and onions altogether. Plus, they won’t have to worry about their breath.

If your dog eats garlic or onions, take him to your vet immediately (the onions don’t have to be raw to be bad for your dog’s health). Digestion can cause severe stomach pain and can lead to stomach inflammation (gastroenteritis).

Some of the symptoms include weakness, lethargy, vomiting, diarrhea, pale gums and breathlessness. Also remember that even the smallest amount of garlic can result in life-threatening problems: in severe cases, garlic or onion poisoning can lead to organ failure and even death.


Macadamia Nuts are poisonous to dogs


Macadamia nuts are very healthy for humans, they have the highest amount of monounsaturated fats of any known seed and contain approximately 22% of omega-7palmitoleic acid, which has biological effects similar to monounsaturated fat. They also contain 9% protein, 9% carbohydrate, and 2% dietary fiber, as well as calcium, phosphorus, potassium, sodium, selenium, iron, thiamine, riboflavin andniacin.

However, we must warn you that these delicious Hawaiian nuts can be dangerous to dogs, although they’re not usually fatal. A dog that has eaten macadamia nuts could experience weakness in his legs and even suffer tremors for up to 48 hours. So if you notice these symptoms, rush your dog to the vet immediately.

Most of us don’t even have Macadamia nuts in our houses, but also be careful when visiting friends and relatives. It’s just a little additional effort that can save your pet a lot of trouble and pain, we are certain that he would do the same thing for you.

Additionally, some dogs will experience health problems after eating them, while others will not. The exact amount that causes health problems can significantly vary from dog to dog. Because of the uncertainty, it is best to completely avoid any food that can harm your fluffy friend.

Like grapes, it is also unknown which toxin causes macadamia nut poisoning. If your dog develops any symptom of food poisoning, take him to your veterinarian.

The signs include vomiting, tremors, hyperthermia and the inability to walk.


Avacado is poisonous to dogs


The avocado (Persea americana) is a tree native to Mexico and Central America, classified in the flowering plant family Lauraceae along with cinnamon, camphor and bay laurel.

Fortunately, cinnamon, camphor and bay laurel are not as toxic to dogs as avocado is. He owes that to one chemical that makes it probably the worst food your furry friend can accidentally eat. All parts of avocados contain the chemical persin, one of the chemicals that was discovered relatively recently in human history but it’s somewhat late discovery does not diminish its negative effects. This substance can be highly toxic to dogs and are also dangerous to many other animals. Birds also seem to be particularly sensitive to this toxic compound.

Persin is a toxic fatty acid derivative, which in sufficient quantity can cause colic in horses and, without veterinary treatment, death. Of course, avocado is perfectly healthy for humans and this does not mean you shouldn’t eat it, just that you need to be careful not to give it to your dog

One of the biggest risks to your dog’s health is obstruction of the gastrointestinal tract, this may occur if your pet swallows the avocado seed. In this case, you should take your dog to the vet as soon as possible.

Also, if your dog experiences vomiting, constipation or diarrhea after eating avocado, consult your vet for advice as soon as possible. Although avocado is found in some commercial dog foods, you should be aware that the avocado is included on the list of foods that can harm your dog.


Alcohol is poisonous to dogs


The thing that is found in alcoholic beverages and is toxic to dogs is ethanol. Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colourless liquid. It’s also a psychoactive drug and is one of the oldest recreational drugs still used by humans. Of course, it can cause alcohol intoxication when consumed.

Dogs can’t process ethonol nearly as well as humans and it can be fatal for them. The same goes for humans, some of us are willing to let alcohol destroy our bodies - but our pets do not have the cognitive ability to make that choice and distinction.

During holiday times, keep in mind that dogs are especially tempted by eggnog. Although some people think that there’s nothing funnier than a dog who had something to drink, this unusual and cruel practice is actually hurting the dogs very seriously, especially if it becomes the habit. So pay close attention to your younger friends and relatives who might try to do something similar and so you need to prevent them from hurting those poor, defenceless animals.

However, you also need to know that poisoning can occur even if your dog doesn’t drink actual alcohol. For example, cakes soaked in rum and similar foods and treats contain yeast and ingesting yeast can result in alcohol poisoning.

If you suspect that your dog is intoxicated, you might need to induce vomiting or even take him to the vet to pump his/her stomach. Alcohol poisoning is frequent in dogs, and even though it’s not intentional in most cases, keep your dog away from hard liquor or foods containing alcohol or yeast, as he will certainly not enjoy the experience.


Bread Dough can be poisonous to dogs


This may seem obvious, but the yeast found in dough is dangerous for dogs. This also means that you shouldn’t, under any circumstances give your dog bread dough, not even in small quantities. The enzymes in the yeast convert the sugar in the dough to ethanol (alcohol) and carbon dioxide. Dogs can’t process ethonol nearly as well as humans and it can be fatal for them.

The carbon dioxide is what makes the dough rise and if happens after the dough had been eaten by your pet, you know where and what will happen. After eating, the yeast can multiply in your dog’s stomach causing pain or even as bad as destroying tissue. The kitchen can be a dangerous place for a dog.

However, by continuously expanding your knowledge and being aware of the hazards, your dog can live a long and healthy life! Be careful with everything in the kitchen and especially take good care of your garbage and make sure it’s properly sealed so that the dogs cannot rummage through it for food.

Even the smallest amount of some foods can actually be very poisonous for you beloved friend. Your home and kitchen need to be dog-friendly. If you aren’t careful enough, your dog could become rather ill from many items it can find in your kitchen.

We have already talked about alcohol poisoning, but what you need to know is that ingesting bread dough can lead to it! The combination of rising dough in your fluffy friend’s stomach and alcohol poisoning can seriously threaten your dog’s health.

It takes approximately one or two hours for the symptoms to appear

Luckily, if you react quickly, your dog will make a full recovery!


Bad or mouldy food can be poisonous to dogs


Another “obvious” advice, as dogs will eat anything they find (fresh and rotten), empty your trash bin regularly because they will sniff out anything that looks edible and eat it, of course. Your household bins are a smorgasbord of tasty morsels for many dogs.

This could cause serious problems and may even be fatal, especially if they ate something with a lot of mould on it. Remember, there are all kinds of mould in the world, but most of them are not just deadly to our pets, but to us as well.

Still, dogs are more likely to eat something mouldy, unlike us. The symptoms that you should be on a look out for are:

  • Seizures
  • Tremors
  • Vomiting
  • Hyperthermia

This toxic mouldy bomb will “explode”, causing severe stomach problems, as the best case scenario - and you don’t want that to happen. Trust us! Mouldy, or food that has gone bad should not be in your house at all and should be properly disposed of, so that even stray dogs cannot get poisoned.

The toxin (found in some moulds) that leads to food poisoning is called tremorgenic mycotoxin. Since you can’t know for sure whether a particular mould contains this toxin, don’t give your pet mouldy food at any cost.

To put it simply, if you wouldn’t eat it, neither should your dog (and many things you will eat shouldn’t be eaten by your dog). If you see your pet eating bad food, try to take it away from him/her. However, after ingesting something that could seriously jeopardize his/her health, it would be best to call your vet and ask for assistance.


Caffeine is poisonous to dogs


While caffeine is something that we consume on a daily basis, this substance is very toxic for dogs. Caffeine poisoning is something that cannot be treated, and for now there is no known cure for this condition.

When consumed in large quantities it can cause an almost instant death, so be very careful with anything that has caffeine as its main ingredient. This especially goes for energy drinks that besides caffeine may also contain alcohol, taurin and other ingredients that may harm and even kill your pet, if you’re not careful.

List includes coffee, tea, Coca-Cola and energy drinks, especially Red Bull that seems to be quite popular among the younger generations, but is highly toxic to dogs.

Again, we have to stress the importance of garbage and its proper disposal, because dogs don’t know the difference between a trash can and a fridge or a pile of food in the yard.


Bones and leftovers can be poisonous to dogs


Give a dog a bone, as the old saying goes, but that is exactly what it is: an old saying and it should be left where it belongs - in the past! We have come a long way and now we have an almost full understanding of the way a body works and what substances are healthy and what substances are hazardous.

You may think that it’s only natural to give lunch leftovers, usually bones with some meat on them, to your dog but this may cause some serious health problems. Some of them even include pancreatitis that can lead to problems with regulating blood sugar levels and digestion. All these problems are very serious and should not be taken lightly, so be very careful when it comes to leftovers.

As far as bones are concerned, they may splinter or break and get lodged inside the intestines or even the throat. This will not only harm your pet but will also take him through painful procedures that cost money and time, so it’s best to be extra careful when it comes to bones and leftovers.


Raw meat and raw fish can be poisonous to dogs


As we get closer to the end of our list, one general rule can be determined: don’t give your dog food you wouldn’t eat yourself. Raw meat can cause various bacterial infections, and the same goes for fish.

Salmon is especially dangerous since it can cause salmon poisoning disease (SPD) that can kill your best friend in two weeks. Salmon poisoning disease is caused by infection with a type of rickettsia, Neorickettsia helminthoeca. Symptoms of SPD begin about one week after eating the salmon and include vomiting, diarrhea, loss of appetite, depression, high fever, and enlarged lymph nodes.

Now, here’s one fact that might frighten you, but you should be frightened when it comes to salmon poisoning disease because it’s no joke: Untreated, mortality reaches 90 percent. These shocking numbers are true, so pay extra close attention to raw and especially raw salmon meat.

Basically, your dog will enjoy himself/herself for a couple of minutes and then he/she will start experiencing stomach pain. The digestive problems can vary from mild to severe, and let’s face it, it’s better to give your dog a healthier and safer treat than to make your fluffy friend go through so much trouble.


Sweets and sweeteners can be poisonous to dogs


Deeply rooted in our culture, this habit has to be changed, for the sake of the dogs. It’s much easier to grab some of the “human treats” like chocolate balls, sweets or even gum and toss it to the dog as a reward than to buy specific treats, especially made for our furry friends that do not contain any harmful ingredients.

Of course, it’s okay to give your dog a treat, but you have to be careful with the kind of the treat.

Many sweets contains Xylitol, an artificial sweetener that causes sudden release of insulin in their bodies. For example, Xylitol can cause liver damage and low blood sugar.

We bet that you heard that the chocolate is bad for dogs, well Xylitol is estimated to be 100 times as toxic as chocolate to dogs.

It is also advised to avoid giving your dog any foods that contain artificial sweeteners, preservatives or additives, check labels carefully, as xylitol is found in many of our everyday foods as a sweetener.

If you truly want to reward your dog, you can find numerous recipes for easily prepared, healthy and safe dog treats. Your furry friend will certainly enjoy them while at the same time eating food that is beneficial to him/her.
