Find details on toxic dog foods below:
Food Poisonous to Dogs
These dog food poison fruits contain seeds or pits that have a cyanide derivative (cyanogenic glycoside) as one of its components. The seeds need to be ingested in large enough quantities.
For dogs, the avocado leaves, fruit, seeds and bark contain a toxic principle known as Persin. The Guatemalan variety, a common variety found in stores, appears to be the most problematic in canine poisoning cases. Avocado in dog food should not be a problem if in a product manufactured by a known company. Symptoms associated with dog avocado poisoning includes damage to heart and lung tissues, diarrhea, vomiting, nasal congestion, problems breathing, and fluid accumulation in the dog heart.
After a party it isn't impossible for a dog to drink alcohol from beer and other unfinished or unattended alcoholic beverages. Dogs can also get alcohol poisoning from eating bakery dough due to yeast fermentation, rum-soaked cakes, Symptoms include staggering, weakness and depression. Small amounts of this dog food poison can lead to death.
The risk from natural chicken or other bones is splintering. Cooked bones are brittle, with pieces breaking off as the dog chews. Sharp splinters can damage teeth and gums, cause choking, or puncture the intestinal tract or stomach. Symptoms include:
- Loss of consciousness
- Dilated pupils
- Face pawing
- Respiratory issues such as shallow breathing
- Gasping for air
The calcium content in bones can result in constipation. If you do want to give your dog natural raw (not cooked) bones, limit them to the safer kinds of bones which are beef knuckles and chicken necks.
Broccoli can cause intestinal irritation in large enough quantities (defined as 10% of the total diet).
Cherries is a food poisonous to dogs due to pits which contain cyanogenic glycosides. It can result cyanide poisoning in dogs.
When dogs ingest citrus oil it can result in vomiting.
Corn cobs from corn on the cob can cause
choking in dogs.
Dog caffeine poisoning symptoms appear within 2 hours after ingestion as the result of the stimulating effect of the chemical. The heartbeat can increase to dangerous levels. Symptoms associated with ingesting caffeine include:
- hypertension (high blood pressure)
- heart arrhythmia, tachycardia (elevated heart rate), abnormal
- hypothermia (high body temperature)
If the dog food poison symptoms are severe your vet will administer activated charcoal, intravenous fluids or induce vomiting. If a dog is experiencing mild symptoms, the prognosis for full recovery is excellent after treatment. Call your veterinarian immediately.
Dogs are susceptible to second hand smoke and the risks of smoking. Dogs that ingest any form of tobacco can get canine nicotine poisoning. Symptoms of nicotine poisoning in dogs include:
- Dog food poison symptoms that can appear within an hour:
- In advanced cases:
- increase in heart rate
- cardiac arrest
- muscle weakness
Dairy products in general are poorly
digested by dogs. They lack the
enzyme needed to properly digest these types of products such as milk
lactose. Symptoms are due to lactose intolerance and include foul
smelling diarrhea and gas.
If you do give your dog dairy products, limit to cheese and plain
yogurt which have lower levels of lactose and are tolerated well by
Dog that eats chocolate is a toxic problem for dogs due to a chemical called theobromine and caffeine. The dog food poison theobromine is a diuretic (increases urine discharge) and a stimulant that can increase the heart rate to dangerous levels.
It is at higher levels in baking
chocolate and dark chocolate It can cause diarrhea
and vomiting and in more severe cases it can cause a heart arrhythmia.
Consumption of higher amounts of chocolate can cause elevated heart
rate, abnormal heart rhythm, seizure, tremors, agitated behavior and
collapse. If you dog only consumed a few chocolate chip cookies or
M&M's it is probably not a dog chocolate poisoning concern.
Symptoms depend on the weight of the dog.
- Unsweetened Chocolate: Approximately 1 square of
unsweetened chocolate for every 10 pounds of weight is a guide for
symptom onset. Unsweetened chocolate is 10 times more toxic than milk
- Milk Chocolate: consuming more than .5 ounces per pound of body weight can put a dog at risk.
- Dark and Semi-sweet Chocolate: Ingesting more than .13 onces per pound of body weight
- Bakers Chocolate: Ingesting any amount can result in dog chocolate poisoning.
Hops, an ingredient in beer, can cause a disease called malignant hypothermia (low body temperature). Greyhounds are most at risk, although all dogs can consume lethal doses of the food poisonous to dogs.
A raw egg contains the chemical avidin which can reduce levels of biotin in the dogs body. Biotin is a B vitamin that supports the coat and growth. Salmonella is also present in raw eggs. Symptoms of dog egg poisoning include:
- retarded growth
- hair loss
- skeleton deformity
Cooked eggs can be given to dogs as a
As you may know, liver is present in
many dog foods and can be
beneficial in small quantities. If a dog eats too much liver, they can
suffer from Vitamin A poisoning, called hypervitaminosis. Symptoms of
canine hypervitaminosis are:
- excessive bone growth on spine and elbows
- anorexia (reluctance to eat, poor appetite)
- weight loss
In extreme cases hypervitaminosis can
result in death.
Macadamia nuts cause temporary paralysis in a dogs hind legs. Often dogs will eat candy or chocolate that contains the nuts. It is not known what causes this condition. 1 ounce of nuts (as few as 6 unshelled nuts) can cause the condition in a 20 pound dog. Symptoms of macadamia toxicity appear in dogs appear in under 12 hours and include:
- joint pain
- accelerated heartbeat
- weakness or paralysis of the hind quarters
- pale gums
- unable to rise
- swollen limbs
- limb pain when touched or manipulated
Dogs recover from this condition in a couple of days. Contact your veterinarian who will provide activated charcoal, administer intravenous fluids and possibly induce vomiting.
Some types, but not all mushrooms are
toxic for dogs. The specific type
of mushroom that causes many of the problems is called Amanita
Phalloides and related species. Eating dog poisonous mushrooms can
cause liver disease and neurological problems. If a dog eats this type
of mushroom the recommendation is to induce vomiting followed by giving
the dog activated charcoal.

Nutmeg is a hallucinogenic for dogs and
can produce the following
symptoms (in larger quantities):
- issues with the central nervous system
Ingestion of nutmeg can result in death
if the quantity is large enough.
Dogs should not be given nuts. They
contain high phosphorus levels that
can contribute to health problems such as bladder stones.
Potato peels and raw green potatoes contain oxalates and solanum alkaloids. These can cause poisoning symptoms in dogs such as urinary problems, digestive issues (vomiting, diarrhea) and nervous system problems (tremors).
Cooked potatoes are not poisonous or toxic
and can be good for dogs.
Dogs that consume too much salt could suffer from kidney disease or from cerebral edema (brain swelling). Large breeds sometimes overcompensate for the salt by gulping too much water. The water in turn creates stomach issues and bloat. Do not use salt to induce vomiting. DO NOT use salt to induce vomiting in dogs due to these canine health risks.
If bloat occurs IMMEDIATE emergency veterinary care is required.
An ingredient in tomato, atropine, is toxic to dogs. It can cause dilated pupils, heart arrhythmia and tremors. The stems and leaves are more poisonous than the tomato itself.
The yeast in dough can rise in a dog's stomach. As the dough produces gas and expands, it takes up a larger area, potentially blocking the bowel or cause the stomach to become distended and then twist (called gastric gilitation and volvulus(GDV). Fermenting yeast produces alcohol which can compound the medical problem with a case of dog alcohol poisoning.
Symptoms from dog food poison cases related to dough poisoning include:
- Unproductive vomiting (no liquid)
- Tachycardia (elevated heart rate)
This condition can cause death and
requires emergency abdominal
The ingestion of raisins, onions, currants
and grapes are foods
poisonous to dogs. Dog food poison symptoms
appear in the first 24 hours after eating.
- Grapes and Raisins: Eating 2 ounces per 10 pounds of a dogs weight in grapes or raisins can cause kidney failure in a small dog.
- Tomatoes: and tomato plants can cause dilated pupils, heart arrhythmia and tremors from the atropine in green tomatoes, leaves and stems.
- Garlic and Onions: 1 If your dog consumes the equivalent
of 1 teaspoon
of garlic for every 10 pounds of their weight (1 teaspoon for a 10
pound dog) can destroy red blood cells (onion destroys red blood cells
as well). Damaged cells are unable to carry oxygen, a condition called
hemolytic anemia. Cooking does
not make garlic and onions less toxic to dogs. Note that many
baby foods contain powdered garlic or onion and should be avoided.
If you dog eats grapes, tomatoes or tomato plants or garlic look for the common symptoms associated with poisoning - diarrhea, vomiting, weakness or lethargic behavior. Your vet will treat with charcoal, vomiting and possibly intravenous fluid.
Not all dogs are sensitive to fruits, so kidney failure problems are unique to each pet. Regardless of your pet's sensitivity, consumption of these items are considered to be a veterinary emergency.
Fat can contribute to inflammation of the pancreas (pancreatitis). Small breeds such as the Miniature Schnauzer, Miniature Poodles, Toy Poodles and Terriers are more at risk than other breeds. Cocker Spaniels are also at risk. Symptoms occur in 1 to 4 days after eating the fatty food (avoid - bacon, turkey skin, sausage, hot dogs, plum pudding, fruit cake, all fried foods) and include:
- reduced appetite
- diarrhea (may contain blood)
- abdominal pain
- acute vomiting (occurs suddenly)
- abdominal pain
- hunched posture
- abdomen splinting when dog is picked up
Rhubarb leaves that are cooked or raw can
induce coma, convulsions
There has been an increase in canine deaths from ingestion of the artificial sweetener xylitol. This is used in many types of products including sugar-free gum, tooth paste and mints. It is also sold as an ingredient for baking. Sugar-free gum in particular is the biggest dog poisoning risk. Xylitol affects the way dog's release insulin, which controls blood glucose. Xylitol promotes pancreatic insulin release. In turn the insulin causes blood sugar levels to rapidly drop. This resulting canine hypoglycemia can result in liver failure or damage. The onset of severe symptoms such as liver failure can occur in less than 2 days.
Dog xylitol poisoning can occur after
consuming as little as one
stick of gum or one breath mint (between .22 to 1/9 gram of xylitol) if
a dog weights 10 pounds.
Symptoms include vomiting after
ingestion. As blood sugar levels
drop, you'll see poisoning symptoms in 30 minutes to an hour including
weakness and lethargy (acting tired). Next you'll observe problems
walking (ataxia), seizures and collapse. It is possible that
symptoms do not appear for a few days.
Treatment for dog xylitol poisoning involves contacting a vet right away. Induce vomiting immediately to remove any xylitol from your dog's system. A vet will check blood sugar levels and may recommend intravenous glucose infusions. Dog's that are quickly treated have a good prognosis for recovery.
Note that some dog toothpastes contain a trace amount of xylitol. These levels are too low to cause a problem.
