Harmful Food Consumption & Toxic Plants
Common Foods/Items That are Harmful Or Even Fatal to Dogs
Many common foods are actually harmful or even fatal to dogs. Some of these (listed below) will surprise you. Others are things you would never give your dog purposefully, but now you will be more careful to not let them be in your dog's reach. And some just need to be limited to small amounts.
Avocados (fruit, pit, and plant) are toxic to dogs. Avocados contain a toxic component called persin, which can damage heart, lung and other tissue in many animals. They are high in fat and can trigger stomach upset, vomiting and even pancreatitis. Symptoms of toxicity include difficulty breathing, abdominal enlargement, abnormal fluid accumulations in the chest, abdomen and sac around the heart. The amount that needs to be ingested to cause signs is unknown. The effects on dogs and cats are not completely understood. GI signs are commonly seen and should be treated symptomatically. In addition, the animal should be monitored closely for other clinical signs related to the cardiovascular system. (This information comes from veterinarians, the American Veterinary Medicine Association, and the ASPCA Animal Poison Control Center.)
Onions destroy red blood cells and can cause anemia, weakness, and breathing difficulty. Even small amounts can cause cumulative damage over time. This includes onions or chives - raw, powdered, dehydrated, or cooked.
Large amounts of garlic cause the same problems as onions. Garlic contains only a small amount of the problematic substance that is in onions. Just as with people, moderation is the key.
Grapes and raisins can cause kidney failure in dogs. As little as a single serving of raisins can kill him. If the dog doesn't eat enough at one time to be fatal, he can be severely damaged by eating just a few grapes or raisins regularly.

Tomatoes (plant and fruit) contain tomatine, an alkaloid related to solanine. As the fruit ripens, the tomatine is metabolized. Therefore, ripe tomatoes are less likely to be problematic for animals. Clinical signs of poisoning include lethargy, drooling, difficulty breathing, colic, vomiting, diarrhea or constipation, widely-dilated pupils, paralysis, cardiac effects, central nervous system signs (e.g., ataxia, muscle weakness, tremors, seizures), resulting from cholinesterase inhibition, coma and death. (This information comes from veterinarians, and the ASPCA Animal Poison Control Center.) (All parts of the plant except the tomato itself are poisonous to humans, although some people are sensitive to the ripe fruit also.)
Tomatoes also contain atropine, which can cause dilated pupils, tremors, and heart arrhythmias. The highest concentration of atropine is found in the leaves and stems of tomato plants, with less in unripe (green) tomatoes, and even less in ripe (red) tomatoes.
Nutmeg can cause tremors, seizures and death.

Caffeine (from coffee, coffee grounds, tea, or tea bags) stimulates the central nervous and cardiac systems, and can cause vomiting, restlessness, heart palpitations, and even death within hours.

Diet products containing the sweetener Xylitol can cause a sudden drop in blood sugar, resulting in depression, loss of coordination and seizures. Unless treatment is given quickly, the dog could die.

Macadamia nuts can cause weakness, muscle tremor and paralysis. These symptoms are usually temporary.

Walnuts. When dogs eat the seed hulls, they can get an upset stomach and diarrhea. The real problem is the fungus or mold that attacks walnuts after they get wet (from rain or sprinklers), which produces toxins. If the fungus or mold is ingested by your dogs, they can become very ill and possibly die. Signs that should alert you to walnut poisoning are vomiting, trembling, drooling, lack of coordination, lethargy, loss of appetite, and jaundice indications such as yellowing eyes and gums. Severely affected dogs can produce blood-tinged vomit or stools. Dogs can take several days to exhibit serious signs of illness.

Chocolate can cause seizures, coma and death. Bakerís chocolate is the most dangerous. The darker the chocolate, the more dangerous it is. But any chocolate, in large enough amounts, can kill a dog. An ounce of chocolate can poison a 30-pound dog, and many dogs will happily consume more than this. The symptoms may not show up for several hours (and so might make you think all is well), with death following within twenty-four hours. A dog can consume milk chocolate and appear to be fine because it is not as concentrated, but it is still dangerous.

Apple seeds, cherry pits, peach pits, pear pips, plums pits, and apricot pits contain cyanide, which is poisonous. While a few apple seeds may not cause a problem, the effects can accumulate over time if they are given to dogs regularly. Dogs should not be allowed to chew on a peach pit, cherry pit, apricot pit, or plum pit. Chewing can allow ingestion of cyanide. Chewing could also result in the pit being swallowed, causing continuous exposure to cyanide, or could cause the dog to choke.

Too much salt can cause kidney problems. Also, large breeds of dogs that eat salty food may then drink too much water and develop bloat, which is fatal unless emergency treatment is given very quickly.

Too much fat or fried foods can cause pancreatitis.

Ham and bacon contain too much fat and too much salt, and can cause pancreatitis. Also, large breeds of dogs that eat salty food may drink too much water and develop a life-threatening condition called bloat. This is where the stomach fills up with gas and within several hours may twist, causing death.

Raw liver or too much cooked liver (three servings a week) can lead to vitamin A toxicity. This can cause deformed bones, excessive bone growth on the elbows and spine, weight loss, and anorexia. Check the label of your canned dog food to be sure that it does not contain liver if you are giving your dog liver also.

Wild mushrooms can cause abdominal pain, drooling, liver damage, kidney damage, vomiting, diarrhea, convulsions, coma, or death.

Raw egg whites contain a protein called avidin, which can deplete your dog of biotin, one of the B vitamins. Biotin is essential to your dogís growth and coat health. The lack of it can cause hair loss, weakness, growth retardation, or skeleton deformity. Raw egg yolks contain enough biotin to prevent the deficiency, so this is not a problem with raw whole eggs. Raw egg yolks could contain salmonella, so you should get your eggs from a reliable source or cook the eggs.

Grains should not be given in large amounts or make up a large part of a dogís diet, but rice is generally safe in small amounts.

Cooked bones can splinter and tear a dogís internal organs.

Dogs can't digest most vegetables (carrots, green beans, lettuce, potatoes or yams) whole or in large pieces. Potato peels and green potatoes are dangerous.

Dairy products are high in fat, which can cause pancreatitis, gas and diarrhea. A small amount of non-fat, plain yogurt is usually safe.

Pennies made from the 1980s to today contain zinc, which can cause kidney failure and damage to red blood cells. A dog that consumes even one penny can become quite sick, or even die, if the penny is not removed.

"My dog ate ______ lots of times and didn't die, so ______ don't kill dogs." That logic is no better than "My dog runs in the street all the time and has never been hit by a car, so dogs never get hit by cars."
The info above is available to anyone with an Internet service, go to: DOG TRICKS, TIPS AND INSIGHTS, Foods that are Harmful or Fatal to Dogs.
All in moderation and depending on your dog, they are all different, yours may handle a few grapes and mine may have problems. I walk on the side of caution, if it might be harmful, I donít give it.

Rat Poison/Bait: Caution!! Please pick up this stuff. You may think it will be safe, it may not be. Rats and mice are known to carry bait back and may drop it in a yard and your dog can get it. Plastic ant poison dispensers can be chewed on also.

Good info.

Not many plants were mentioned so I thought I would add a couple off the top of my head being that I am into gardening and horticulture.

Oleander - One of the most poisonous of all plants!
Digitalis (Foxglove) - Still used in heart surgeries for it's effects on the heart
Angel's Trumpet - LSD like effects although the "trip" is terrifying.
Castor Beans - These are what the deadly poison Ricin is made from
Rhododendron and Azalia - Both are poisonous.

There are many others but these are some that came to mind. ;)

Remember that many of these have to have quite a bit ingested to be deadly and I don't think most dogs would find them tasty enough to eat that many. It is something to keep in mind though.

i was told to feed my pit raw whole eggs, because its good for there skin and it keeps them calm. because cooked eggs make them hyper?


Wild mushrooms are very important to consider, as i had two of my boys, as pups(like 12 weeks) eat death caps, and got REAL sick. I noticed when i went to put on their bed and they were stiff. After investigating i found the mushrooms. They were definitely tripping and acting wierd when i woke them. They both threw up once and slept practically the whole day. They pulled out of it and have shown no ill signs, no more mushrooms though.

Chocolate is toxic to dogs...

Here is a link to a chart showing the effects of chocolate on dogs by their weight:

The Chocolate Chart Interactive - National Geographic Magazine

And some useful info below.

Toxic Levels

The good news is that it takes, on average, a fairly large amount of theobromine 100-150 mg/kg to cause a toxic reaction. Although there are variables to consider like the individual sensitivity, animal size and chocolate concentration.

On average,
Milk chocolate contains 44 mg of theobromine per oz.
Semisweet chocolate contains 150mg/oz.
Baker's chocolate 390mg/oz.

Using a dose of 100 mg/kg as the toxic dose it comes out roughly as:
1 ounce per 1 pound of body weight for Milk chocolate
1 ounce per 3 pounds of body weight for Semisweet chocolate
1 ounce per 9 pounds of body weight for Baker's chocolate.

So, for example, 2 oz. of Baker's chocolate can cause great risk to an 15 lb. dog. Yet, 2 oz. of Milk chocolate usually will only cause digestive problems.

Clinical Signs

Xanthines affect the nervous system, cardiovascular system and peripheral nerves. It has a diuretic effect as well. Clinical signs:

Hyper excitability
Hyper irritability
Increased heart rate
Increased urination
Muscle tremors


There is no specific antidote for this poisoning. And the half life of the toxin is 17.5 hours in dogs.

Induce vomiting in the first 1-2 hours if the quantity is unknown.

Administering activated charcoal may inhibit absorption of the toxin. An anticonvulsant might be indicated if neurological signs are present and needs to be controlled. Oxygen therapy, intravenous medications, and fluids might be needed to protect the heart.

Milk chocolate will often cause diarrhea 12-24 hours after ingestion. This should be treated symptomatically (fluids, etc..) to prevent dehydration.

I recently switched my dog's food and since then my cat will not stay out of it. Usually I don't have much of a problem keeping the animals in there own dish but she is persistant. She still eats her own food, but I keep catching her steal a large kibble and run off with it. I then find piles of vomit and I know its from her. My dog eats only when she is hungry so it doesn't work to only feed the dog at a certain time of day I have tried. Any suggestions? Is this harmful to her to have a kibble here and there?

THC in marijuana can be fatal to a dog also.It takes about 1.5 grams of marijuana per pound of body weight to be fatal. So if you are 420 friendly keep the stash put up so fido don`t ingest it and die.

Question - my dog Lily loves v8 juice but I am unsure if it is safe for her? Google has provided me with mixed answers. Thank you!

ashes 04-29-2011 07:54 PM

we have an avacado tree and all my dogs have eaten them when they drop and I'm talking three a day at least or more. And neither of them had problems or gotten sick from it?? My eldest died at the age of 18 and never had to be taken to the vet for any illness. Just the occasional shots. All my dogs grow up on avacados and they love them?????

So the white is bad due to it causing biotin loss, but the yolk compensates by providing more than enough biotin to make up for it? So would it be safe to assume that egg yolks are ok, long as they're cooked/boiled ?

I would feed my previous pit raw eggs (cracked over the dry food once a day, white and all) and every now and then provide a fish oil capsule. His coat was super shiny with that combo (with decent dry food and exercise of course). Should I continue, modify, or completely quit this diet with my new girl?

Any advice would be much appreciated.
