Top Poisonous Foods for Dogs

With the recent food recalls in the news, and E.Coli infections, it’s obvious that food poisoning can happen to humans. However many young dog owners don’t know that food poisoning can happen to dogs also. Although a lot of owners love to give their dog table food, some different types of food can be poisonous and very dangerous. Here is a list of some of the major foods to avoid feeding your dog.

1. Chocolate- While most of us enjoy eating a delicious piece of chocolate, chocolate can be very lethal to your dog. It’s not the chocolate itself which is harmful to your dog, but rather the theobromine contained within the chocolate. Theobromine can cause different reactions in dogs; if your dog has epilepsy, then theobromine can trigger epileptic seizures. Other effects include cardiac irregularity, internal bleeding, cardiac arythmia and death.

2. Walnuts- Walnuts are considered a very healthy food for humans, however walnuts (amongst many other kinds of nuts) can have harmful side effects on dogs. Because of their high phosphorous content, walnuts can potentially give your dog bladder stones.

3. Onions- It’s not like your dog will enjoy eating those stinky things anyways, but you should definitely avoid feeding your dog onions. Onions, especially raw ones, are known to cause hemolytic anemia in dogs. For those of you who don’t have a MD, hemolytic anemia is where red blood cells are removed and destroyed from toxic compounds.

4. Potatoes- Poisoning from potatoes have been known to occur for both humans and dogs. This is from the Solanum alkaloid that is found in green sprouts and green potato plants. However, this doesn’t mean that all forms of potatoes are bad for your dog. Mashed and cooked potatoes are actually quite nutritious and healthy for your dog, but stay away from raw uncooked potatoes.

5. Turkey Skin- When Thanksgiving rolls around, the last thing you want to do is feed your dog leftover turkey. Turkey Skin has been found to cause acute Pancreaitis in dogs. Pancreaitis is where the pancreas becomes inflamed and can lead to bleeding in the gland, tissue damage and infections.

6. Sugarless Candy- Candy may be a great treat for kids, but they are definitively a big no-no for dogs. Some candies contain a compound called xylithol which can lead to liver damage and death in dogs.
If you’ve fed any of these to your dogs recently, it’s recommended you contact your vet as soon as possible. It’s important to note that different types of foods can have different effects on your dog. Make sure you know what your dog can and cannot eat.

  1. Dogs have a good sense of smell but sometimes they made great mistakes and eat food placed on streets which is very harmful and poisonous for their health.

  2. excellent article! this information is sooo very important for all dog owners!

    I have also read and have been told that grapes/raisins are toxic for dogs.

  3. Along with the grapes and raisins I have also read that chocolates are also harmful for the dogs because the cocoo used in making the chocolate are harmful for the growth hormones

  4. Does anyone know for sure about the grapes? My dog LOVES them and I would hate to be giving him something that is doing him harm.

  5. I googled it up and couldn't find any real scientific studies on grapes being toxic. I did however find one study which was done by the ASPCA which handled a study of 140 dogs and the effects of grapes on the dogs. A third of them developed symptoms of vomiting to kidney failure - however they say that the dog had consumed between 9 ounces to 2 pounds of grapes.

    I would personally advice against giving your dog grapes, as it seems the case is still unsettled as to wether they are in fact toxic or not, but I have given my dog a few grapes on multiple occasions and have not noticed any ill effect. I'm pretty sure that feeding your dog a few grapes here and then isn't going to hurt him, but it is common sense not to give him something like two pounds of grapes, any large amount would not be recommended.

    In the end, it's always better to prevent than to cure, so it's up to you to make that decision!

  6. Hi Jean. Thanks so much for looking that up. I might avoid them just in case.

  7. i also know onions are toxic to dogs, unfortunalty ive seen the reactions i used to work at a vets and had some dogs come in after eating food scraps with onions in it they kind of go into welts that looked like they have been stung by millions of bees and they go down hill very fast

  8. Just to add a note, I noticed a large posting on the bulliten board at my local vet's - it was a warning not to feed your dog grapes. Something about them using new chemicals in the production.

  9. You mean the pesticides? I guess those aren't any good for us humans either...

  10. Here's a good site:
    peteducation.com
    Go to:
    Dogs/first aid emergencies and poisons/poisons and toxic foods/foods which are toxic/foods to avoid.
    There is a lot of other info as well.

  11. Here is a Direct Link to the comment posted above.

  12. Another one that most people don't know about is sugar-free gum, specifically those that contain xylitol as the artificial sweetener (xylitol can also be found in human toothpaste and mouth wash). It can cause hypoglycemia (low blood sugar) for days, thereby causing seizures, and sometimes even liver failure. Both of which can cause death in severe cases.

  13. Wow I never knew about that!!! I'm wondering if it has the same affect on humans? (To a degree of course)

  14. From Wikipedia (Which is sometimes about as reliable as asking your neighbour for a scientific opinion, but...)

    Quote:
    Xylitol, like most sugar alcohols, can have a laxative effect, because sugar alcohols are not fully broken down during digestion. It has no known toxicity, and people have consumed as much as 400 grams daily for long periods with no apparent ill effects.

    Dogs ingesting foods containing high doses of xylitol (greater than 100mg xylitol consumed per kg bodyweight) have presented with low blood sugar (hypoglycaemia) which can be life-threatening. Low blood sugar can manifest as loss of coordination, depression, collapse and seizures as soon as 30 minutes after ingestion.

    Intake of very high doses of xylitol (greater than 500 - 1000 mg/kg bwt) has also been implicated in liver failure in 8 dogs, which can be fatal.

    One reported death occurred in a standard poodle who ate five or six cookies sweetened with xylitol.

    Dogs that have eaten products containing high levels of xylitol might need immediate medical attention even if they are not yet showing illness. Sick dogs (vomiting, weak, seizuring, etc) are likely to need aggressive veterinary treatment and close monitoring of blood values.


  15. Re: the grapes. I asked my vet about them because one of our favourite past times is watching our girls chase grapes along the floor trying to eat them, it's really quiet fun. they are not poisonous but they do cause bad gas in dogs that aren't accustomed to them. If you've been feeding your puppy grapes since they were little there shouldn't be any problems if you just start at about 1 or older you'll likely find bad gas is associated with grape eating but it is not harmful.

    As for onion, I live in an apartment building and for some reason people like to throw food off their balcony, mostly onion and chicken bone, be very careful of BOTH. COOKED chicken bone is very dangers the little shards of it breaks of as it becomes very brittle and can seriously injury your dogs throat (it is not a pleasent experience) onion can also make your dog very, very sick, but they like it! Go figure, many dogs are attracted to things that make them sick (so says my vet).

    Chocolate! This is true that BAKER'S CHOCOLATE can seriously injure your dog, but milk chocolate and most dark chocolate will likely do very little. Not that I would suggest stuffing your puppy filled with chocolate but an averaged sized dog can eat a whole easter bunny solid milk chocolate treat and show no effect (depending on the sensitivity of your dogs stomach). It is the bakers chocolate that even a lick of will leave your dog in serious trouble. So while I still wouldn't leave your chocolate hanging around for scruffy to eat, if he does get a hold of it, just watch him but probably no need to rush to the vet (or so again our vet said)

    Not really true. The problem is that the toxin has not been identified: it could be pesticide, or it could be a particular species of mold, etc, which means that not all grapes may have the toxin on it, but we won't know when you get that one grape that may have the toxin either. To be on the safe side, I wouldn't feed my dog grapes at all to avoid the potential problem.

    Depending on the amount ingested, it can cause death by making the hemoglobin unable to bind to oxygen. It's almost like death by carbon monoxide.

    Again, it depends on the amount ingested. You don't have to worry as much with a great dane as you would with a chihuahua. Toxic dose for milk chocolate is about 1oz chocolate per 1# of dog.

  17. Good thing I read the comments here, didn't know about grapes. Haven't given any grapes to my dogs, but in general they love tangerine, pineapple and apples.

    Something to worry about is the Blue-green algae toxins found in ponds. My babies love to drink from the pond, I blocked access to it. I don't know if my pond contains this particular algae which can be deadly, but better safe than sorry.

  18. For anyone who feels it is good to feed their dog grapes or raisins, here is an e-mail I have received recently:

    Quote:
    I just came across your public access page on Toxic Foods for dogs that people may not be aware of and you missed a major, major one -- grapes, and to an even greater extent raisins, can be deadly. My friends almost lost their dog to kidney failure after he ate a bunch of raisins. He was in the clinic for 3 days on intravenous. Just thought you might want to add that one.
