    By Janice Jones     |Last Updated 07-21-2022

    There are some foods toxic to dogs, but otherwise perfectly
    safe and loved by us humans. 

    It’s often
    hard to resist those large dreamy eyes expectantly staring into your face as
    you take a mouthful of a scrumptious chocolate cake, but don’t give into that
    little dog of yours. 

    It might add pounds
    to you but it does far worse to your four legged companion.  Just what are some of those substances and
    foods dogs should never eat?

    Foods that Dogs Should Not Eat

    Foods Toxic to Dogs List



    Love that guacamole? 
    Well, it doesn’t like dogs.  Avocados
    often top the list of foods toxic to dogs. 

    Avocados contain persin, a fungicidal toxin which is normally harmless
    in a human but can be toxic to dogs. 

    Persin is in the leaves, seeds, bark and fruit of the avocado plant so
    beware if you happen to have a few growing in your yard. 


    A mug of beer show, an example of a food that dog shouldn't be given to eat or drink.

    Maybe not the best choice of liquid
    hydration in people, it is also not good for dogs. 

    Alcohol including beer, liquor, wine and any
    foods made with alcohol causes the same effect on a dog’s brain and liver as it
    does in human, but the result is much faster and the speed increases as the dog

    Just small quantities can produce
    vomiting, diarrhea, depression, coordination problems and even difficulty
    breathing, coma and death.  It might be
    cute, but it is deadly. 


    High up on the list of foods toxic to dogs is onions and garlic. 

    Dogs Should not Consume onions.

    Onions are bad, no matter
    what form they take-raw, cooked, dehydrated or in a powder form – they all can
    destroy the red blood cells in a dog’s circulatory system, leading to Hemolytic

    Even baby food has some onion
    powder, so beware. We really don’t have a good idea on the quantity that is
    bad, but the cumulative effect of eating onions is what is problematic.   

    not likely to cause much trouble if eaten in tiny amounts occasionally, but if
    it is part of a regular diet, can poison the dog over time. 

    Anemia can cause weakness, vomiting, dull
    coat, anorexia and breathing difficulties. Kidney damage may follow.

    Garlic is one of those controversial foods. One camp says that dogs should not eat any garlic and the other camp thinks garlic is good for dogs.

    Coffee, Tea, and
    Other Caffeine

    Dogs should not consume caffeine

    Very few dogs like the taste of black
    coffee, but add some sweetener and flavoring you’re your little guy might just
    like a sip or two.  

    But caffeine in any
    form whether it is from coffee, tea or sodas can be fatal if consumed in large
    enough quantities. 

    Symptoms can include
    heart palpitations, fits, muscle tremors, restlessness and even bleeding. 

    Caffeine can also be found in some
    medications and chocolate, another major No No for dogs.

    Grapes and Raisins

    Grapes and Raisins are toxic to dogs.

    Grapes and raisins are two foods toxic
    to dogs and currants can be added to this category as well. 

    Both grapes and raisins can cause
    irreversible kidney damage and even death. 
    Even a very small amount such as 4 or 5 grapes or raisins can make a 20
    pound dog very sick. 

    Vomiting, lethargy,
    loss of appetite, abdominal pain, coordination problems decreased amount of
    urine production and depression are symptoms. 

    While symptoms usually occur within 24 hours, they can start in just a
    few hours after the dog has ingested the grapes or raisins.

    Milk and Other Dairy Products

    Cows milk is not appropriate for dogs.

    Who hasn’t been guilty of giving a dog
    a little taste of ice cream or other dairy products? 

    Dogs do not tolerate cow’s milk as well as
    people and anything made with milk such as cheeses, yogurt or plain milk can
    have the potential to cause digestive upset, usually in the form of diarrhea.  

    A teaspoon now and again is not going to hurt
    them.  If your dog is intolerant to cow’s
    milk, goats milk is a good alternative and products made with goats milk seem
    to be tolerated better in dogs. 

    Dogs on
    a complete and balanced commercial diet should not need additional calcium in
    their diet with the exception of lactating mothers. Goat’s milk is the safest product to give to young puppies and lactating mothers.

    Macadamia Nuts

    Macadamia nuts are poisonous to dogs

    Another group of foods toxic to dogs is nuts.  Dogs should not eat nuts, but macadamia
    nuts seem to be the worse culprit for making dogs ill and death is not out of
    the question.

    Even a few roasted or raw macadamia nuts can cause muscle
    tremors, weakness or paralysis, vomiting, fever and rapid heart rate. When chocolate
    is mixed with the nuts, the symptoms worsen. 
    Symptoms often show up within 6 to 24 hours. 

    Types of Nuts

    To be safe, don't feed nuts to your dog.

    To be absolutely safe,
    Dogs should not be given nuts to eat. 
    Nuts that should be added to the list of foods toxic to dogs
    include:  Almonds, Pistachios, Pecans,
    Walnuts and Hickory Nuts. 

    They vary in
    the harm they do to the dog.  Moldy nuts
    are toxic while the fresher version of the nut just makes your dog sick.  Dogs seem to love the taste of almonds, but
    they are not well digested giving your dog and upset stomach. 

    Pistachios have a high
    fat content and can cause stomach upset as well.  Dogs that eat pistachio nuts over a period of
    time can also develop pancreatitis.   

    Black Walnuts are known to cause stomach
    distress and even obstructions if swallowed whole.  But if a dog gets a moldy black walnut, that’s
    another story. 

    Moldy black walnuts
    contain toxins produced by a fungus which leads to lethargy, vomiting and loss
    of muscle control. Like black walnuts, English and Japanese walnuts can cause intestinal
    upset resulting in a stomach ache, vomiting or even an obstruction. 

    Just like black walnuts, English and Japanese
    walnuts that contain a mold that releases a tremorgenic mycotoxin which the dog
    ingests causing muscle tremors or seizures. 
    Hickory nuts and pecans both follow the same patterns as walnuts. 

    Fresh hickory nuts will cause a tummy ache
    while moldy nuts can be affected with the tremorgenic mycotoxin.


    Chocolate is not a food that dogs should eat. Showing is a box of chocolate.

    Most people know that chocolate is bad
    for dogs but did you know that even white chocolate can cause symptoms and dark
    chocolate and unsweetened baking chocolate is the most dangerous.

    A 20 pound
    dog can be poisoned on 2 ounces of baking chocolate, but it would take 20
    ounces of milk chocolate to cause harm. 

    toxic agent in chocolate is Theobromine.  Chocolate can cause vomiting diarrhea and
    increased thirst, tremors, seizures, abnormal heart rhythm, coma and death. 

    Peaches, Plums and
    Persimmons, Apple Seeds, Cherry Pits

    The seeds or pits of fruits like peaches are dangerous to dogs.

    Included in this section of foods toxic to dogs is not so much the food, but rather the seed.  The problem is not so much with the fruit, but with the seeds or

    Many small dogs will eat the pit
    which contains cyanide which is a known poison to both dogs and people.  If that doesn’t hurt them, intestinal obstruction
    is a real possibility. 

    Peaches, and Plums Seeds or Pits.  Don’t
    let a dog eat apple seeds or cherry pits as they can wreak havoc giving your
    dog an upset stomach and possible cyanide poisoning. 

    Dogs can eat apples and most love them as a
    very special treat, but don’t know not to eat the seeds.  If you do serve these apples, core them as
    you would a small child.

    Raw Eggs

    Cooked eggs are fine but raw eggs could be dangerous

    Dogs seem to love eggs, but cook them first
    if you intend to serve them.  There are
    two problems with giving your dog raw eggs.

    The first is the possibility of
    food poisoning from bacteria like Salmonella or E. coli which is why raw eggs makes the list of foods toxic to dogs.

    The second is that an
    enzyme in raw eggs interferes with the absorption of a particular B vitamin.

    This can cause skin problems as well as problems with your dog’s coat if raw
    eggs are fed for a long time.

    Yeast Dough

    Unbaked bread yeast dough

    If you make your own bread, be sure to
    allow the bread to rise in a place where the dog cannot reach it. 

    If a dog eats the dough as it is rising, it
    will continue to rise in his little stomach. 
    You can just imagine what happens next — as the dough rises, it
    stretches the stomach wall causing severe pain. 

    Beyond that, the yeast which makes the dough rise begins to ferment in
    the stomach which can lead to alcohol poisoning.   


    An ingredient in human toothpaste, gum, and mouthwash, is a substance that is toxic to dogs.

    This odd sounding chemical is the
    sweetener often found in toothpastes, mouthwashes, some medicines and sugarless

    You can also find it in many baked
    goods and that is why this common ingredient makes the list of foods toxic to dogs. 

    While being recommended for human
    diabetics, it is definitely not recommended for dogs. Xylitol causes a rapid
    rise in insulin levels which leads to hypoglycemia. 

    Symptoms in dogs can range from vomiting,
    lethargy and poor coordination to seizers possibly leading to liver failure.

    Wild Mushrooms

    Unless you are an expert on wild mushrooms, don't feed them to your dog.

    Wild mushrooms — those that grow in
    your backyard or along a trail can be dangerous not only to you but to your

    People know not to sample them, but
    dogs can be curious.  Toxins in the mushroom
    can create havoc with many different organs including the liver, kidneys and

    Symptoms include vomiting, seizers,
    coma, and even death.  So check your yard
    periodically and remove any mushroom looking plants.

    Fat Trimmings and

    Dogs love fat and bones, but fat
    trimmings are not good for you and not good for your dog. 

    Here I am referring to the cooked or uncooked
    fat trimmed from meat that the humans did not want.  Too much leads to pancreatitis. 

    Bones are different.  Cooked bones are the most dangerous.  They can break or splinter as the dog gnaws
    on them causing the dog to choke or create lacerations in the digestive wall
    and even obstructions.  Fish bones are
    especially problematic. 

    There does not
    seem to be this type of problem with uncooked bones and so uncooked bones have
    become a part of a raw diet.


    Limit the amount of salt your dog ingests. Shown is a salt shaker.

    When dogs ingest large quantities of
    salt, it leads to excessive thirst and subsequent urination. 

    This usually happens when a dog gets too many
    salty foods.  It the salt intake is large
    enough, sodium ion poisoning occurs. 

    Symptoms include vomiting, diarrhea, depression, tremors, fever,
    seizures and even death. Think twice about allowing your dog to help themselves
    to those salty treats. 

    So when you sneak
    your tiny dog into the movie theater, don’t let them eat all your popcorn!

    Human Vitamin Pills
    that Contain Iron

    Some medicines are fine, but some are dangerous to dogs.

    It is tempting to give our fur children
    the same medicine we give our human babies, but before you do so, make sure it
    is not toxic to dogs. 

    There are some
    human medicines that are fine for dogs, but not all of them and some can be
    very dangerous. 

    Human vitamins that
    contain iron can damage the wall of the stomach and intestines and be toxic to
    the liver and kidneys. 

    OK, OK, vitamin pills are not food, but
    some might argue that statement.  I added
    this to the list of foods toxic to dogs, just to see if you would catch my

    Take-a-way for Foods Toxic to Dogs

    Prevention is easier than the cure and much less
    costly.  Know that you are familiar with
    the foods toxic to dogs, you will be less likely to allow your small dog to
    come into contact with those dangerous substances. 

    Things happen often very quickly.   

    do you do if you suspect that your dog has consumed a substance or food likely
    to be toxic? 

    Keep the phone numbers of your
    veterinarian and 24 hour emergency veterinary hospital handy and make a call as
    soon as you discover what has happened.
