Can My Dog Eat This? Foods That Are Toxic To Dogs!

Are you one of those owners who spoil their dogs with food? Be careful! There are human foods that are toxic to dogs!


Chocolates, pizza, and Mexican food — you love all these scrumptious food items and think your dog deserves to taste these heavenly delights. Stop! These foods are dangerous for your dogs. As a responsible dog owner, you must know what human foods are toxic to dogs.



Chocolate is one of the most common human foods that are toxic for dogs. Chocolates are toxic not only to dogs but many animals due to their alkaloid chemical content, known as methylxanthines: theobromine (3,7-dimethylxanthine) and caffeine (1,3,7-trimethylxanthine).

Just like in humans, these chemicals stimulate the nervous system of animals, especially dogs, and affect the cardiovascular health. Humans can get away with these effects because our bodies metabolize these chemicals quickly. But in dogs and other animals, these chemicals are slowly processed so the effects are more prominent.

They say the darker the chocolate, the more dangerous it is – and that is true. White chocolates contain lesser methylxanthines so they’re less toxic than the darker ones. If a dog ingested too much caffeine and theobromine, he will start to show a number of symptoms, such as vomiting, diarrhea, muscle spasms, excessive panting, hyperactive behavior, seizures, and dehydration.

Dogs that have ingested too much chocolate may also become hyperthermic, have cardiac arrhythmia, or go into respiratory failure – all of which can be fatal.



Guacamole tastes awesome but you might want to hold off sharing it with your pooch. Avocado contains a toxin called persin and even its leaves, pit, and the fruit itself can be toxic. In dogs, this can cause an upset stomach, breathing difficulties, and fluid buildup in the chest.


Cow’s Milk

You may think that milk is perfectly fine for dogs. They are mammals after all, and they drank milk from their moms when they were young. Yes, dog’s milk is good for them but you might want to hold back in giving your dog cow’s milk.

Like in humans, dogs may suffer from lactose intolerance from drinking cow’s milk as it contains sugar that cannot be broken down by dog stomachs that don’t have the enzymes to do so.


The consumption of cow’s milk could lead to vomiting, diarrhea, tummy upset, and other GI problems. While ingesting milk isn’t going to kill your dog right away, it can lead to serious bacterial exposure in dogs that can cause illness.


Bacon may be tasty but it is bad for you — it’s even worse for your dog. As dog owners, we can’t help but spoil our beloved furry buddies with the best-tasting food. Fatty foods like bacon can cause pancreatitis in dogs. When a dog has developed pancreatitis, his pancreas becomes inflamed and stops functioning properly — leading to digestion and nutrient absorption problems.

Cheese and Other Dairy Products

Cheese and other dairy products also have fatty components and sugars that the dogs digestive enzymes can’t break down. If consumed in excess, cheese and other dairy products can cause problems. When a dog consumes too much cheese, a dog may have gas, diarrhea and may vomit.

Simple Tips For Choosing The Best Sensitive Stomach Dog Food


Onion and Garlic

Pizza, nachos, and onions pretty much go with anything savory. One may think that the strong scent of garlic and onions will make food more interesting for dogs but they are a no-no for our furry friends.

Onions and garlic contain certain compounds that can be harmful to dogs. They can damage their red blood cells, which can make them weak. A blood transfusion might be necessary if your dog consumes too much of onions or garlic.


Macadamia Nuts

Luckily, macadamia nuts are something dog owners don’t think of feeding their furry friends but they can be incredibly harmful to dogs if eaten. Dogs who have ingested macadamia nuts will develop weakness and an inability to walk — specifically in their hind legs.

Dogs who consumed macadamia nuts may experience vomiting, a staggering gait, depression, tremors and hypothermia. It is still unknown what makes macadamia nuts toxic to dogs.


Grapes and Raisins

Grapes and raisins may be healthy for humans but it doesn’t mean that these sweet fruits are good for Fido. The chemicals and compounds that cause toxicity to dogs is currently unknown but the consumption of grapes and raisins can cause rapid kidney failure.

Other than kidney failure, dogs may also vomit, have diarrhea, and become lethargic. Dogs who consume grapes and raisins may experience dehydration and loss of appetite. Dogs with kidney failure may die within three to four days.


Apple Core

People always avoid eating the core of an apple, and it is the same for your dog.

Apple cores are very toxic to dogs so never leave them laying around for your dog to snatch and consume. Apple cores — and other fruits such as peaches, plums,  pears and apricots — may contain chemicals, depending on the fertilizers used, and when a dog ingests them, he may suffer from seizures, dizziness, breathing problems, heart collapse, or hyperventilation. Your dog might even go in coma.



Most dog owners think feeding their puppy bread is fine but it really isn’t.

Raw yeast dough used for making bread can ferment inside your dog’s stomach and become toxic since the fermentation can produce alcohol inside the stomach. Aside from that, yeast dough can also expand inside your dog’s stomach and create a large amount of gas in his digestive system. This can cause your dog severe pain and may rupture his stomach or intestinal tract.



No, your dog does not need coffee to be awake. Never let your dog consume coffee or anything with caffeine. Coffee and other caffeinated foods and beverages contain a stimulant called Methylated xanthine, which is a compound that overstimulates the nervous system in dogs. This causes dogs to vomit, become restless, suffer heart palpitations, and even death.
