Foods that are toxic to dogs




Not sure what foods are toxic to dogs? We get a lot of phone calls at the hospital asking us, “My dog just ate a ____, should I be worried?” Although there are some human grade foods that are nutritious to dogs as shown above, there are also some that can be seriously harmful. I have put a list together that shows what foods you should never allow your pup to have.





I have heard stories about teenagers giving dogs alcohol at high school parties and getting them drunk just to amuse their guests. If only they knew how poisoning it is to a dogs body. Alcohol can cause not only intoxication, lack of coordination, poor breathing, and abnormal acidity, but potentially even coma and/or death.


Apple Seeds:

Apples themselves are not bad for dogs, it is more of the apple seeds that are toxic. They contain a natural chemical (amygdlin) that releases cyanide when digested. This is really only an issue if a large amount was eaten and the seed were chewed up by the dog, causing it to enter its blood stream. But to play it safe, be sure to core and seed apples before you feed them to your dog.



Avocados contain Persin, which can cause diarrhea, vomiting, and heart congestion.


Cooked Bones:

Most people think that it is safe to give their dogs bones from their leftover dinners. They are right in a way…… Raw (uncooked) bones, are appropriate and good for both your dog’s nutrition and teeth however, cooked bones are known to easily splinter when chewed by your dog which can cause damage to their gums, teeth, and throat; causing pain and even potential injury. If your dog swallows the shards from cooked bones, he or she also runs the risk of internal injury.


Candy and chewing gum:

If your pet has their nose in your purse like mine always love to do, make sure they aren’t able to sniff out your gum packet. Any gum or candy that contains “Xylitol” can lead to the over release of insulin in their body which can cause kidney failure, and worse.



The famous one that everyone in the world knows about. Not only does the caffeine in chocolate cause problems for dogs it’s also the theobromine and theophylline in it which can cause the dog to start panting, vomiting, and have diarrhea. It can also damage their heart and nervous systems. So make sure those yummy homemade chocolate cupcakes that you just made are hidden somewhere where your dog can’t sniff them out!



I don’t know about you but I can’t start my morning off without having a big cup of fresh coffee. If your dog decides to feel the same way that morning and ends up drinking your entire hot cup of jo, we may have a problem on our hands. While 1-2 laps of coffee, tea or soda will not contain enough caffeine to cause poisoning in most pets, the ingestion of moderate amounts of coffee grounds, tea bags or 1-2 diet pills can easily cause death in small dogs or cats

Corn on the cob:

We all enjoy a nice corn on the cob at a barbecue party paired with some barbecue ribs and baked beans but if your dog decides to join in on the festivities we can assure you that Max will not be feeling too hot after. If a dog eats corn it is a sure way to get their intestines blocked. The corn is digested, but the cob gets lodged in the small intestine, and if it’s not removed surgically, can prove fatal to your dog. Additionally, too much corn kernels can upset the digestive tract as well so be cautious to not feed too much.


Fat Trimmings:

There you are eating your delicious home cooked meal and you decide to look down at the floor and you see Max staring at you with those beaty eyes and slobber drooling down his mouth. You think you are doing him a favor by giving him your scraps but really it is the complete opposite. Feeding them fat trimmings from our food can cause serious pancreatitis which means a not so fun visit to the doctors where they could potentially be hospitalized for days getting fluids and treatment. Just give them their favorite treat instead trust me their stomach will thank you for it later.


Grapes and raisins:

This is one that lots of dog owners are unaware of. Grapes contain a toxin that can cause severe liver damage and kidney failure. We’ve heard stories of dogs dying from only a handful of grapes so do not feed your pup this toxic food




Macademia Nuts:

 These contain a toxin that can inhibit locomotory activities, resulting in weakness, panting, swollen limbs, and tremors as well as possible damage to your dog’s digestive, nervous, and muscle systems.


Milk and dairy Products:

Many of you might not know this but dogs are actually lactose intolerant and when they drink milk or consume dairy products they can get the same side effects as humans such as diarrhea and gas.



Just as the wrong mushroom can be fatal to humans, the same applies to dogs. Don’t mess with them!



We all thought that chocolate was the absolute worst thing that you could give your dog but onions happen to be in the same category. It does not matter if they are raw, cooked, dry or in powder form. They contain disulfides and sulfoxides (thiosulphate), both of which can cause anemia and damage red blood cells.


Peaches and pears:

I know a lot of home owners enjoy having fruit trees in their backyard but certain ones can be harmful to your pooch if they pick them up off the ground and ingest them. Peach pits are not only a choking hazard they contain amygdalin, a cyanide and sugar compound that degrades into hydrogen cyanide (HCN) when metabolized. Pear seeds also contain trace amount of arsenic and are dangerous.





Just like salt isn’t the healthiest thing for humans, it’s even less healthy for dogs. Yes it tastes good but the side effects of having too much of it just doesn’t make it worth it. Overdosing on salt can lead to an imbalance in electrolyte levels, dehydration and potentially diarrhea.



I don’t know about you but I have a major sweet tooth. Chocolate, sour candies, gummy worms you name it, but too much of it can cause serious health problems in the future. Same thing goes for dogs, too much sugar can cause obesity, diabetes and dental issues.


A major toxic hazard for dogs (and humans). The effects nicotine has on dogs are far worse than on humans. Nicotine can damage your pup’s digestive and nervous systems, increase their heart rate, make them pass out, and ultimately result in death.




 If you’re planning on making some homemade bread for dinner tonight make sure your pup isn’t around. Just like yeast rises in bread, it will also expand and rise within your dog’s tummy. Make sure they don’t get any. While mild cases will cause gas, lots of farting, and discomfort – too much of it could rupture their stomach and intestines.
