As a dog parent, you know that your dog is an unconditional lover and would do anything for you. Dogs can’t be picky eaters at all and will usually try anything once. As a responsible dog owner, you must consider what your furry friend eats because of the health risks it can potentially cause. Some foods are toxic to dogs that require immediate vet treatment costing potentially hundreds or thousands of dollars. we as dog parents have to make sure that they are eating the healthy stuff if we are to keep them as healthy as possible. Sometimes you won’t be able to catch it in time but if you know just a couple of foods that are toxic for dogs, it shouldn’t hurt your pup too badly depending on how many ingredients were in what he ate accidentally. Make sure your fur baby does not  swallow something toxic.
Dogs have voracious appetites and don’t always know when to stop eating. Although some foods are not toxic in small doses, larger quantities can be fatal. Signs of food poisoning in dogs can vary widely, but key symptoms include vomiting, diarrhea, dilated pupils, loss of appetite, restlessness, staggering, and disorientation. If you suspect your dog has eaten something toxic, Vets Now recommends that you never induce vomiting unless a poison control expert has instructed you to do so as certain substances can actually cause more damage coming back up – better left in a dog’s stomach then brought back up into a dog’s mouth later on if it hasn’t already hurt the stomach.

Why Cheese is Bad for Dog?

Although most people know not to feed chocolate and alcohol to their pets, many do not realize that some of the regular foods in their homes are very toxic for their animals. Traces of chocolate and xylitol can be found in a lot of candies and different food products – even those advertised as safe for consumption by both humans and pets. The ASPCA warns that grapes and raisins, nutmeg (particularly dangerous for dogs), macadamia nuts, onions, garlic, leeks, potatoes, avocado and certain types of mushrooms may also be poisonous or harmful to our loved ones’ health because they have high levels of glycoalkaloids that make them unsafe for consumption. Sometimes, owners give these harmful foods to their dogs and cats. But a lot of times, pets accidentally ingest these foods which happen to be commonplace in homes. The researchers found that pet poisoning cases have involved chocolate-based foods as well as chives and daisies, macadamia nuts and yeast dough among others. They also found that animals tend to get sick from plant foods in the Allium genus (including onions, garlic, leeks and chives), macadamia nuts, Vitis vinifera fruits (including grapes, raisins, sultanas and currants), beverages which contain ethanol such as beer or wine although in smaller amounts than rum or whiskey , as well as unbaked bread dough.

List of Foods Your Dog Should Never Eat

Grapes, raisins, and currants


Grapes and Raisins are not safe for all dogs. So, if your dog ingests any grape or raisin related food product you must take them to a vet immediately.  Shedding light on the problem; the symptoms of dog poisoning with grapes or raisins can be lethargy, vomiting and diarrhea (in some cases) which can occur 12 hours after consumption. If these symptoms remain without treatment they might lead to dehydration, decreased appetite and increased urination which manifests into enlarged kidneys.  Long-term kidney disease may cause permanent damage over weeks to come if not treated. They can put them in serious danger by causing kidney failure within days of ingestion. Ouch! Your dog might develop long-term kidney disease or die from kidney failure within three to four days.

Salty Food

salt for dog

You may have heard that popcorn and pretzels are bad to feed your dog because they can cause a condition called sodium ion poisoning which is different than the common table salt. Symptoms of eating too much salt can be vomiting, high body temperature and even seizures if you feed your dog bacon which contains a high level of salt. Salt is toxic to dogs so make sure you keep it to a minimum in the foods you share with your pup. Large amounts of salt can result in a lot of thirst and frequent urination, or even salt poisoning in our pets.

Signs that your pet may have ingested too much in the way of salty foods include stomach pain, vomiting, diarrhea, excessive thirst, depression, tremors, elevated body temperature levels and even death as a result. Because we love our pets so much and don’t want to see anything bad happen to them (listed above), we encourage you to avoid feeding potato chips, pretzels and salted popcorn to your pets.
Dogs need a lot of water. That’s because they can quickly develop dangerously high blood pressure if they don’t drink enough water, which can make them really sick. Dogs are especially at risk during hot weather, when they won’t want to drink as much, so it’s important that you regularly provide fresh drinking water for your dog to enjoy. Dogs have a very high level of sensitivity to salted foods and they do not react well to salty treats. Be careful when you prepare food for your dog, make sure you watch what ingredients you use and learn exactly how much salt is good for your pet. Dogs are even more sensitive than humans, which means that many foods can be harmful for them in large quantities. Make sure there is always fresh water available for them at all times, and never feed them salty food.

Sugar / Xylitol


The next most common toxic foods for pets are products sweetened with an artificial sweetener called xylitol. Xylitol is a common artificial sweetener that can be found in several products including candy, gum, desserts and even some medicines. While this sweetener can help diabetics maintain their blood sugar levels it may be harmful for dogs if ingested in large amounts. The Pet Poison Helpline released a statement advising owners to seek emergency treatment immediately if they suspect that their dog has ingested foods or medicines containing xylitol. If your dog accidentally ingests large quantities of this sweetener symptoms such as vomit, loss of coordination and lethargy should subside within three hours without the need for medical attention – but only if your dog receives the proper treatment.
Xylitol is also found in products used to help us cure certain illnesses such as cancer. In serious cases, it can literally save lives – especially when there is no other option. Among animal species, when xylitol is consumed by dogs it leads to a sudden release of insulin causing blood sugar levels to plummet. Signs of severe poisoning include vomiting and seizures. Xylitol, when consumed can lead to hypoglycemia in dogs. Symptoms include vomiting and signs of lethargy.



When it comes to the top bad foods for dogs, chocolate tops the list as it can be extremely harmful – not just to young pups but all dogs of all ages. It can cause a dog to vomit or drink excessively, experience tremors and seizures, and even worse strokes and heart failure! Save the sweet treats for yourself instead and make sure that you’re keeping your pal away from this potentially fatal food group. It is usually most common question that why chocolates are bad for dogs because we want same treat for our furry buddy. Chocolate contains a chemical called theobromine, and it’s one of the most poisonous substances for dogs. The type of chocolate that your dog ingested, as well as how much they ate and their weight will determine if they’re going to be sick or will recover from eating it. Theobromine and caffeine in chocolate speed up the heart rate of your dog and stimulate its nervous system. Why Chocolate is bad for your dog because it contains a substance called Xylan that can affect dogs, cats and some animals. It is commonly found in humans, dogs and plants including avocado, beets, tea, prunes and tomatoes. Although dark chocolate affects dogs most severely, any amount of chocolate in a pet can trigger its copper deficiency. Symptoms are very dangerous if not fatal within 24 hours to your furry best friend.

Cheese, Milk and Dairy Products

You may have heard the rumor before that dogs can eat cheese and that it won’t kill them like other food items. However, this is indeed not true. Cheese is a dairy product and as much as you may convince yourself that dogs are cheese experts, this doesn’t change the fact that they’re lactose intolerant. Imagine how horrible your stomach would feel if you ate something like pizza, a milkshake or cake – perhaps even solids would make your stomach churn at the sight of them. The same goes for any pet dog. Besides upset tummies, cheese can cause weight gain, allergies and even diabetes because of its high fat content. According to Dogs Naturally Magazine’s article on dairy, ‘It [cheese] has some similarities to human lactose intolerance… the result is gas associated with both diarrhea and constipation.’ So what do you give your pooch instead? Dairy-free “pet cheeses” such as simulated mozzarella and cheddar from Alpo Pet Products.. You may have slipped your dog a pill in a piece of cheese, but dogs just aren’t built to process cow milk products. They lack the enzyme required to break down milk sugar, and while some dogs are more able to handle dairy than others, many dogs are lactose intolerant. Dairy can cause them to vomit, have diarrhea or develop gastrointestinal diseases. The high fat content can lead to pancreatitis (just like bacon), as is the case with fatty foods. Don’t share your ice cream if you want your pup around for another day

All mammals are designed to drink milk from their mothers as infants, gradually weaning off as they grow and transition to water and solid foods. After infancy, it’s not uncommon for mammals to experience some level of lactose intolerance when consuming milk products in general, including those from other species. So while milk may not technically be poisonous for your dog, it’s worth keeping on its “do not feed” list. Some dogs are OK with it, but others experience extreme discomfort in addition to potential health problems, especially among certain breeds. On the other hand, you can find plenty of healthy food options that your dog will like and feel much better about eating regularly, without the same possible side effects many will experience if they have too much milk.

While small doses of milk and dairy items are fine for pets, it could make your dog quite gassy, often causing plenty of flatulence, which is essentially almost the same situation as in humans. In addition to this, milk and dairy products could cause digestive problems that could lead to cases of vomit or diarrhea. Getting your pooch a food allergy test at one point will let you know more about potential health issues



Much of the controversy around avocados when it comes to dogs involves persin, which is toxic in high doses. When an avocado is ripe, its persin levels drop, so the danger should disappear after that. It’s not so much the danger of persin as it is the fact that many older dogs don’t chew their food completely and as a result, might not be getting all the nutrition they need from avocados alone. Well, avocados can be deadly for dogs. There has been several news reports of fatality cases in the United States of and elsewhere because they eat unripe avocado fruit or even stems and pits. If you grow avocado plants in your house or yard, to be on the safe side, make sure you keep your dog away from fruit that has not ripened. Unriped avocados can cause stomach and intestinal problems so eating it is definitely a no-no. Make sure you remove the pits before giving your dog any avocados because they can get stuck in its throat or lead to gastrointestinal blockages which could be fatal if left untreated. While most conditions are treatable, neither we nor our vet wants you or your beloved pooch to run the risk of something happening due to an easily avoidable circumstance such as this one! If you decide to take the plunge anyway, make sure that you give him ripe avocados only. The persin contained in avocados is what causes possible negative reactions. So if your furry friend loves them and they come from the local supermarket and are ripe that means they are safe to relish! But always consult a vet prior (during) a procedure involving food sharing so that no one becomes sick on an empty stomach.

Garlic, Onion and Mushrooms

Mushrooms onion garlic for dogs
Mushrooms can be extremely fatal to both dogs and humans. Dogs should not be given mushrooms under any circumstance. Mushrooms can cause organ failure from what we’ve researched so far, and there is a high chance that a dog might mistake certain mushrooms for food which can result in an extremely fatal outcome. Does your dog eat mushrooms? What kind of mushrooms are these? Please consult with our veterinarian immediately.

Though garlic, onions, leeks and chives may seem like a healthy addition to your pet’s diet, they actually contain toxic elements that could damage your dog or cat’s blood.  These common ingredients contain compounds called organo sulfoxides which if consumed can create damaging sulfur compounds. Any animal who chews on this plant will develop red blood cell disruption as a result of these toxins. If the dog or cat ingests even just a piece of an onion (specifically 5 grams of onion per kilogram of body weight for cats – 15 to 30 grams per kilogram for dogs), it can cause dangerous changes to the animal’s blood and should be monitored immediately. Eating garlic right before hanging out with buddies or kissing your significant other may make for an awkward time for you and them. But what about snacking on it every day? Although people have eaten garlic for thousands of years without any problems, in high amounts, it can kill you. The effects from a large dose are similar to arsenic poisoning. Questionable breath is one thing when eaten in small doses but can be harmful when consumed in large amounts. This food may just work better when taken in moderation, because not everything good is meant to be used at maximum dosage. Garlic, chives, shallots and scallions are harmful to dogs. They contain compounds that can cause anemia, gastroenteritis and other very serious damage to the red blood cells. Garlic is considered five times as potent as onions. The signs of onion or garlic poisoning often don’t appear until 2-3 days after ingestion but include lethargy, weakness and orange- to dark red-tinged urine. Japanese dogs such as Akitas and Shiba Inus tend to be more sensitive to garlic and onions than other breeds.

Buy products that are specifically made for dogs. Make sure you talk to your vet about whether or not there is food that is okay to share with your dog, but for the most part you should stick to what is okay for them and buy them their own food. If your dog does ingest any human food and experiences negative side effects, take him or her to a vet right away and tell your vet what it was they ate.
Avoid feeding your dog uncooked yeast dough, seeds and pits from fruit, raw potato, cooked bones, apple cores (when giving it to them as treats), alcohol, caffeine, and human medicine. This can lead to potential poisoning. Choking can occur if your pet gets a hold of these items. It can also cause gastrointestinal issues.
