25 Things Your Dog REALLY Can’t Eat!

25 Things Your Dog REALLY Can’t Eat!

toxic for dogs

Can I Eat That?

As I was steamcleaning the cantaloupe juice out of the carpet the other morning (one of my dogs had snacked on the fruit that had been sitting on the kitchen counter top), I realized that I did not know whether cantaloupe was toxic for dogs. In fact, I wished I had an easily accessible catalog of toxic foods for cases such as this. I often have people calling me in a panic because their dog ate something and they don’t know what the potential consequences are.  I have put the following together based on experience and research–I was especially surprised to learn about the dangers of avocados!

First of all, there does exist a National Animal Poison Control. You can look them up on the web at Animal Poison Control or give them a call at 800-426-4435. The drawback is that the fee for the call is $60, however in times of need, this is no more than the typical co-pay for a human to go to the emergency room. My experience and that of my clients has all been very positive with this organization.

Foods That Are Toxic To or Just-Plain-Bad for Dogs


  • Can cause intoxication, coma, and death


  • The fruit, pit and plant are all toxic. The toxic ingredient in avocado is called persin. They can cause difficulty breathing and fluid accumulation in the chest, abdomen and heart, vomiting, diarrhea, death, inflammation of mammary glands, cardiac failure, respiratory distress, generalized congestion, abdominal enlargement.

Apple, Almond, Apricot, Peach, Cherry, Plum, Pear, Prunes & similar fruit:

  • The seeds of these fruits contain cyanide, which is poisonous to dogs as well as humans causing diarrhea, vomiting, abdominal pain, (Stem, Seeds and Leaves).

Baby Food

  • Can contain onion power which can be toxic to dogs


  • Gastrointestinal irritant

Cat food

  • Usually too high in protein and fats.


  • Chocolate can cause seizures, coma and death. Baker’s chocolate is the most dangerous. A dog can consume milk chocolate and appear to be fine because it is not as concentrated, but it is still dangerous.

Citrus oil extracts

  • Can cause vomiting

Coffee, Coffee grounds, tea and tea bags:

  • Drinks/foods containing caffeine cause many of the same symptoms chocolate causes

Eggs (raw)

  • Raw eggs can cause salmonella poisoning in dogs. Dogs have a shorter digestive tract than humans and are not as likely to suffer from food poisoning, but it is still possible. If your dog has a partial blockage in their intestines where food can be trapped, e coli or salmonella could breed more easily.
  • Egg white contains the protein ‘avidin’ which forms a stable and biologically inactive complex with biotin. The avidin in egg whites will tie up the biotin so it cannot be used by the dog.”**

Fat Trimmings

  • Fat trimmings can cause pancreatitis


  • Human vitamin supplements containing iron can damage the lining of the digestive system and be toxic to the other organs including the liver and kidneys.

Macadamia Nuts

  • Macadamia nuts can cause weakness, muscle tremor and paralysis.


  • Can depress the nervous system, cause vomiting, and changes in the heart rate.

Milk and other dairy products

  • Some adult dogs do not have sufficient amounts of the enzyme lactase, which breaks down the lactose in milk. This can result in diarrhea. Lactose-free milk products are available for pets.


  • Acute gastric effects, liver and kidney damage, abdominal pain, nausea, salivation, vomiting


  • Tremors, seizures and death


  • Nausea, salivation, vomiting, tachycardia (rapid heartbeat)


  • Gastrointestinal upset, anemia, destroys red blood cells

Grapes, Raisins, Prunes

  • Kidney failure, as little as a single serving of grapes or raisins can kill a dog.

Persimmons Seeds

  • Can cause intestinal obstruction and enteritis

Potato peelings and green looking potatoes


  • Excessive intake can cause kidney problems


  • Tomatoes can cause tremors and heart arrhythmias. Tomato plants and the most toxic, but tomatoes themselves are also unsafe.

Yeast Dough

  • Can expand and produce gas in the digestive system, causing pain and possible rupture of the stomach or intestines


This list is not meant to raise alarm – only to inform you about what to look out for. And notice… cantaloupe is not on the list! Hooray!

    XYLITOL!!! Absolutely deadly for dogs… According to our vet, worse than anything on the original list. It is an alternative sweetener, touted as “natural” and in gums, candies, and now I noticed in Spies yogurts. After sei, uses, coma, and days in the hospital, my 110 pound sheepdog is still alive. My Vet says the only one he’s had that survived! Please pass this on and Insist that your supermarket or natural foods store posts many warning signs.

    Raw eggs are good for dogs as long as they aren’t the main meal, my dog eats all raw and he loves when he gets raw eggs, it’s a great source of good nutrition!

  3. Anne December 4, 2013 at 1:43 pm

    Hi I’ve been feeding my dog a mix of eggs sweet potato mixed frozen veggies (( corn Lima beans green peas carrots green beans) and chicken livers . Everything is well cooked I also supplement with 1 fish oil capsule twice a day he is 11.80 pounds and I feed him 2 1/2 cups a day. Does this sound like a good diet?

    • Lynne Miller July 11, 2014 at 2:18 pm

      Anne, dogs need protein, why are you not feeding your dog, dog food? It has all the vitamins, and minerals that your dog needs in it. If you have to feed him something you make, I would put some ground turkey in it, also watch his/her weight, if the dog starts putting on weight, cut back on some of the carbs, and use green beans as a filler. But if your in doubt double check with your Vet.

      • lily August 13, 2014 at 8:46 pm

        dog food is not a good diet unless it is organic(if you now what it is) they sometimes use mice killing chemicals a lot of people even use it in human food but even if it is organic you should still look at the ingredients.

      • lisa September 7, 2014 at 5:47 pm

        Are you not aware that eggs and chicken livers are very high grade sources of protein? I ssuggest you do some research on commercial prepared “dog food” and educate yourself on how bad they really are.

    • Rachel September 23, 2014 at 12:55 pm

      Hi Anne (and anyone else this can help)! A dog that size does not need that much food. 2.5 cups of food is for a 50-pound dog, not 12 pounds. I’d cut him back to 1/2 cup 3 times a day, then 1/2 cup twice a day. I have an 8 lb Pomeranian and, per my vet’s instruction, I feed her 1/4-1/3 cup 2 times per day depending on how active she’s been (less for lazy days, more for active days). Also, if you’re going to cook for your dog, you might as well give him good stuff. Stick with 1 lb lean ground meat, 1 cup brown rice or sweet potato (not both), 1 cup carrots and/or green beans, and 1 bunch of parsley, chopped. Cook, mix, and put in baggies or containers in serving sizes (I do 1/4 cup for my dog, but you should do 1/3-1/2 cup), and freeze them. Pop them in the microwave to thaw for meal time! You can add the fish oil after cooking or to each cup. But never feed him corn. It’s a filler that his body was not made to process. That recipe I got from my vet as well. Hope that helps!

    is ham and turkey aready cooked good far dogs

    • Jennifer January 1, 2014 at 4:10 pm

      You should NEVER give dogs raw or even cooked Turkey or Ham. Both cause extreme conditions of vomiting and diarrhea.

      • Tanner February 24, 2014 at 12:49 am

        Raw turkey and ham are fine for dogs as long as it’s not processed. If your dog is experiencing diarrhea and vomits it is probably because your dog isn’t used to it. My 9 month old puppy is on a raw diet and eats basically any type of meat and has never had a bad reaction to Turkey or ham.

      • Lynne Miller July 11, 2014 at 2:13 pm

        You wrote that you can not give a dog cooked turkey, that is not true. My Vet has told me on many occasions, when my dog has an upset stomach to cook ground turkey, and rice. Because it is very easy for them to digest, so I’m not sure where you got your information on that one, but you may want to do a little more checking.

    • brooke January 7, 2014 at 7:02 pm

      yes as long as there is no bones and is cut not big

    • mascie April 19, 2014 at 12:41 pm

      if u haven’t noticed there is no pet dog foods on the market with pork…. this is for a good reason … pork is very bad for any animal i only found this out by talking to 3 different vets and they all agreed it is the worst meat product u can give a animal

      • mascie April 19, 2014 at 12:50 pm

        also one thing i forgot to add my friend had 3 large breed dogs they where on a homemade raw food diet as she wanted to make sure nothing she didn’t want wasn’t going to be in her dogs food after she went through all her beef and chicken premade food she desided to make one with pork well all 3 of her dogs died with in 48 hours of eating it

        • Lorraine November 24, 2014 at 7:16 am

          Although ham is from a pig too, pork is an entirely different way in preparation, I know myself & my 2 sisters & my 2 daughters,pork causes a bad stomach pain,yet my hubby & others have never had a problem….pork is one cut of meat,that is not for everyone,so I can understand why pork is not good for dogs.

    • lily August 13, 2014 at 8:48 pm

      you can try raw chicken thighs.

  5. Austin December 13, 2013 at 8:49 pm

    i just gave my dog a meatball and she seems to be fine.

  6. Freddy December 20, 2013 at 10:47 pm

    I was surprised when I read that tomatoes were not good for dogs. My dog will be angry as she just loves spaghetti sauce or anything that is made with spaghetti sauces or pizza sauce! We have let her have a small saucer of spaghetti when we eat during spaghetti night suppers and she hasn’t dropped a morcele of sauce or anything. Please advise me if I really am ok or do we really have to curtain the spaghetti thing?

    • Fghjklas January 21, 2014 at 12:46 am

      Be safe. Better safe than sorry

  7. wolfdog January 8, 2014 at 9:49 pm

    Your dog can REALLY eat raw meat. Just know where your meat is coming from and thats its fresh.

  8. Laz January 9, 2014 at 1:19 am

    I’m getting a dog late this month and I’m just researching. So thank you this really helped

  11. John Ward January 27, 2014 at 10:53 am

    Hi All just a quick question, My daft Mini Schnauzer has to my shock eaten 4 uncooked sprouts. I s this harmfull

    • admin January 28, 2014 at 7:19 am

      Your dog is probably fine, but the best option is ALWAYS to check with your vet.

  12. Angel Horrigan January 27, 2014 at 12:01 pm

    My dog loves eating raw tomatoes, and has never gotten sick from it. Should I stop her from eating them?I kinda ddon’t want to stop her eating them if it’s not serious. She loves them. Also, she only eats the small yellow tomato variety.

    • lily August 13, 2014 at 8:52 pm

      you can always try something else like chicken or other things if it likes it you can change

  13. nas January 28, 2014 at 7:10 am

    My dog has tried different foods at times that other ppl say that you shouldn’t give your dog that it could cause wateva.. yes some foods are toxic but so are foods us humans eat..there’s to many opinions that think they know it cause they are sheep or there animal has eaten something it shouldn’t have.. they were fine hunting and eating things for survival before even known as pets to mankind.. this post isn’t to upset anyone just having a say like everyone else

  14. nisha February 1, 2014 at 12:03 am

    i gave my dog peaches and he was fine so i dont if i should stop

    • Rachel September 23, 2014 at 1:09 pm

      It’s not the fruit that is bad for dogs, just the seeds. So just make sure the seed is in tact and not in the fruit when you give it to him. You don’t want to accidentally slip him any fragments that may harm him. Also everything in moderation is always safer than in large doses, so just give him a couple of pieces a day, not an entire fruit.

  15. nisha February 1, 2014 at 12:06 am

    and i gave my dog hot dogs chopped up and he is fine cuz we just had hi check up last week

  16. Spencer February 3, 2014 at 8:55 am

    My dog ate something that i don’t know of and now she is acting very lethargic and is vomiting. I have no idea what she could’ve gotten into.

    • admin February 3, 2014 at 1:19 pm

      Please take your dog immediately to the vet then. You don’t want to take any chances – a trip to the vet could save you a lot of heartache.

    • hope April 15, 2014 at 2:40 pm

      Always keep charcoal on hand. Available at any feed storew.

  17. Betty February 5, 2014 at 7:23 am

    I feed my dogs only grain free dog foods and meat scrapes . No. Sweets and no bread.
    I do give them cream cheese for giving pills.
    The three that our now gone lived to 15 years old.
    If they go to mcdonalds they get a hamburger minus the roll .

  18. Carmela February 5, 2014 at 4:52 pm

    Can I give my dog meatball with no tomato sauce just boiled in water

  19. Elizabeth Scott February 20, 2014 at 1:30 am

    We almost lost our small dog from cooked turkey.she was throwing up, lethargic, not eating and blood from both ends.she was sick for a week.We had x-rays done and the blood test was perfect.She had a lot of gas in her intestines.A lot of prayers food ground up and force fed her with an eye dropper and lots of pedialite.A thousand tears later and shes back on her feet.

  20. lexi February 22, 2014 at 12:22 am

    my vet reccomends baby food for dogs when they are constipated… my vet is awesome and never makes stuff up

    • Lorraine November 24, 2014 at 7:21 am

      Some baby food contain onion,it’s on the ‘bad’ list for dogs, perhaps your vet is unaware that it has onion in it,but then again,if it’s only occasionally,probably not a biggy ;)

  21. Donovan March 10, 2014 at 8:34 pm

    my dog is eating apple but she only eat the fruit not the middle part, i think she know seeds are bad for her, raisins my dog love so much.. my dog is very healty the problem is he dont like rice.. only meat, fruits, liver and vagetables…

  22. Amanda March 29, 2014 at 1:29 pm

    You forgot macadamia nuts! they are bad for your dog. You shouldn’t give your dog macadamia nuts or foods containing macadamia nuts because they can be fatal as few as six raw or roasted macadamia nuts can make a dog ill. Symptoms of poisoning include muscle tremors, weakness or paralysis of the hindquarters, vomiting, elevated body temperature, and rapid heartbeat. Eating chocolate with macadamia nuts will make symptoms worse, possibly leading to death.

  23. Kim Anderson April 5, 2014 at 9:04 pm

    Our docs are also grain free but eat all vegis and fruits they want….2 lived to 18 yrs old! Current golden retriever loves 90% all vegis and fruit! I think, just like humans, each dog is different. Ours gets sick from cooked meat! Great Vegan she is, O
    ops she loves her seafood as we’ll:-)

  24. Jessi April 6, 2014 at 3:06 pm

    I live on 13acres that are wooded and my dogs eat everything from acorns to walnuts they even catch small wild animals at times and our veggie patch is never safe from them. The only things I try to keep from them are citrus fruits and chocolate all of them except two are in the double digits now so I believe they know what they can and can not eat out doors . Some vet think anything that does not come from them is bad for dogs so it really is up to you to know your pup .

  25. Ollie April 7, 2014 at 12:49 pm

    I give my dichon cesar canine cuisine mixed with all meats except pork as long as they r well done however i saw blood in her stool this morning and she refuses eat. I have made an appt. She can’t be seen until wednesday should i try and make her eat, ??

  26. Jordan April 21, 2014 at 6:11 pm

    My grandparents dog is gonna become obese and hes only a italian greyhound. He eats all the meats on here. Eats off the table. Its ridiculous.

  27. Fran April 27, 2014 at 1:16 am

    Walnuts will cause renal failure in cats and dogs.

  28. sue May 1, 2014 at 11:41 am

    My vet told me that processed ham can cause pancreatitis in large amounts. Ripe cherry tomatoes are fine & a great way to hide a pill. Green tomatoes and the plant itself can be toxic however.

  29. cheri May 9, 2014 at 11:43 am

    My doberman ate wild mushrooms in backyard and became lethargic and foaming at the mouth so we gave him 2 tablespoon of peroxide and started the vomiting immediately. He was fine after a couple hours. I feed him bread to soak anything up in his stomach. It was scary, we thought we were losing him. We check the yard everyday for mushrooms now. He eats watermelon, apples, raw potatoes, peas, corn, cantelope and is a healtjy 80 pounds

  30. Smbat May 21, 2014 at 9:40 pm

    Of course we have an avocado tree and a grape tree in the yard. Not to mention onions that my mom grows. And some mushrooms that naturally grow out. So I try to keep avocados away from my dog. I’ve seen them vomit that out and they seem to steer clear from it now. But so,entires when I’m not home squirrels will feed on avocados and the half eaten avocado will fall from the tree and my pups will feed on them. They don’t yet have their rabis shots. Will they get rabies from eating foods left over from squirrels or rats? And are those mushrooms that grow naturally dangerous?

  31. lisa arthur June 7, 2014 at 3:40 pm

    I just gave one of my dogs a few (3) bites of canteloupe about an hour ago. Well was downstairs for 3-4 min. came upstairs to vomit all over my dining room floor. How did I know it was the dog that ate canteloupe? Yeah, you can probably guess! eww

  32. Kristi-Lee Boladeras July 6, 2014 at 7:21 pm

    So are they allowed to eat those stone fruit if we remove the seeds? I always give them loads of fruit but I always take out the core and seeds. Hope im not slowly killing them?!! :-/

  33. jake July 12, 2014 at 10:13 am

    I feed my dog Mars bars, steak and milkshake daily…. He seems to enjoy it but recently he’s been sleeping for over 15 hours and difficult to wake for his morning chocolate bar, please advise

    • admin July 12, 2014 at 10:26 am

      It would be a very good idea to talk with your vet about what constitutes a healthy diet for a dog. In the long run, your dog will thank you! -Danielle

    I have a poodle that came from the pound. that means that she was fixed. So therefore, I am told she is going to be overweight, no matter what is that true? she is kind of big, what can I do? should I accept it has a unavoidable fact Or can I fight it?

    • Dorene July 24, 2014 at 5:51 pm

      I have a 4lb poodle (teacup) now 13 years.
      I had her fixed when she became the right age. My little Vali Girl is the right weight for her size. I use to think that if they got fixed male or female they would get fat. Anyway I was told that. But I’m here to tell you it’s not true ! Both of my dogs never got fat .)

    My Maltese is a very picky eater, today I found out that she likes vegetarian meat patties, cooked chicken meat and bones, bread. Are these ok for him to eat? I just adopted him, he doesn’t like dog food. I am not an expert at this. can anyone help?

  40. Linda L. September 7, 2014 at 7:58 pm

    I left a tray of grape tomatoes (3+dozen), on a chair on the deck.
    When I went to retrieve it, it was gone. Less than 24 hours later,
    my dog was dead. I had killed her, because she loved them. I had taught her to.
    No tomatoes for dogs. :(

  41. j. joseph September 13, 2014 at 3:38 pm

    My coton de tulear loves baked sweet potatoes , Brussels sprouts broccoli , string beans and cottage cheese . Since she eats sweet potatoes every day , she no longer has tear stained eyes. I had heard that this breed was once vegetarian . Think it depends on the breed as to tolerance . My mother had a pug that ate grapefruit everday.

Balance? may be that’s the key in this ocean of different opinions….but then here says tomatoes are poison for them so i dont know what to think.q
