    Were they human-safe mushrooms? If so, they shouldn’t cause a problem. It is some kinds of wild mushrooms, the ones that are also toxic to humans, that are toxic.

  • Heather Meachum

    My dog got into the trash and ate spaghetti that had mushrooms in it

  • sandy

    Preferably without the onions and soy sauce.

  • Nadeen Alderman

    can a dog eat a pork eggroll?

  • Dog_Obsessed

    Dairy, especially in large amounts, can cause stomach upset in some dogs. It’s not poisonous though. It would be similar to a person being lactose intolerant. Again, this is only in some dogs.

  • Dog_Obsessed

    The core is also bad, for the same reason as the seeds, and also a choking hazard. The rest of the apple should be fine though, including the peel.

  • Amanda

    Apples are safe, the seeds can be poisonous since they contain arsenic, but the rest of the apple is fine. May cause gas though, so only a little at first until you know. I can toss an entire cored apple to my dog, she’s been eating them for 7 years.

  • floridagirl83

    My dog loves apple peelings does anyone know if they are harmful to dogs. Thank you

  • cyndishisara

    Yes, sorry I am so (mentally) slow. I would think people from India would have something to say on the subject. They must feed their dogs curry all the time with no ill effect. I guess I have been initially fear struck about peoples cautions (do not remember where I saw them) about turmeric and ginger. I wish I could focus on how to season my dogs food to make it tasty for her.

  • theBCnut

    And that’s exactly my point. There is research done on foods that are bad, but they don’t bother to do research on ones that are not a problem. People just use them and no one reports that it killed their dog, because it didn’t. As far as therapeutic dosing of turmeric and ginger, they are used in the same dosages as they are for people. A 100 lb dog would be given a full dose, a 50 lb dog would be given a half dose, a 25 lb dog would be given a quarter dose. If you need a paper to prove it, good luck. They may be out there, but I haven’t seen them. Sometimes you can find some research done on people, but that doesn’t mean it applies to dogs, especially if good science matters to you.

  • cyndishisara

    Of course, I was referring to information on turmeric and maybe ginger. I can look for myself. With xylitol, garlic, onions, chocolate, macadamia nuts, and avocadoes (persin) there is research showing ill effects.

  • Lynne Tighe-Boland

    I don’t see dairy on the list, but have heard it is a problem for dogs.

  • theBCnut

    I haven’t seen a study proving that beef or chicken are safe for dogs to eat, but we feed them beef and chicken all the time and they don’t die from it, so even though I don’t have a study, I know it’s OK to feed. Sometimes common sense has to prevail.

  • Dori

    Dogs should not be fed onions.

  • cyndishisara

    Thank you. I will try it. But remember science is about research that keeps all factors the same and alters one. No ensure this the sampling issue (a large # of dogs so are studied to factor out genetic variability and pre-existing health conditions are not include) and a control group is needed.

  • cyndishisara

    To whom? Are you brainwashed by the eighty years of propaganda that goes on even until this day?

  • theBCnut

    The amount that would cause noticeable problems is different for every dog. It depends on several different factors.
    The amount that you would have on your fingers and that would come off on something else is negligible, so not a problem.

  • janet1111

    does cross contamination make a dog sick like if you peel an onion and then touch their toy can they get sick and how much onion do they have to ingest in order to get sick.

  • theBCnut

    Actually, onions in any amount are toxic to dogs, just not deadly. They cause a reaction in dogs that destroys red blood cells. If only a few RBCs are destroyed then you will never notice. But if enough are destroyed, the dog can not recover. Some dogs seem to be more susceptible than others, but all are affected.

  • Jared French

    Very small amounts of fresh onion is not toxic. Cut onions, however, are very efficient at absorbing toxins from the air or whatever else they touch. This is why they can be dangerous, not only to dogs, but also to humans, if not eaten shortly after being cut.

  • Susan

    In Australia people have been taking heap oil & its supose to do wonders, for cancer patients,epilepsy, etc now they are trying to pass something thru government, so it can be bought legally from a chemist with a prescription…

  • Timbeans

    quite the opposite. look up Dr Courtney’s research on that topic. raw cannabis is an amazing medicinal plants. its raw forms are much different that heated ones. also, CBD, found in the plant, shows great medicinal potential.

  • Abby Lawless

    isn’t eating mirjuana bad anyway O.o anyway what about onion powder seasoning on a bit of hamburger?

  • ryanna

    Ok thanks

  • sandy

    MSG in soy sauce can be problematic. It can potentially be addicting and is an excitotoxin according to Dr Russell Blaylock. You can read more about it his book “Excitotoxins The Taste That Kills”.

  • ryanna

    Whst about soy sauce

    Your welcome!

    Thank you!

  • Dog_Obsessed

    I’m so sorry for your loss. Please don’t blame yourself, we all make mistakes.

    *WARNING GRAPHIC* But people need to be aware! I had to moved from a condo because of one too many dogs and he was such a good dog, it was worth it… moved to the county with a nice huge yard for them to have a blast and the same dog I moved for decided to eat mushrooms… Now these looked like some ordinary mushrooms, not bright in color or slimy like you would think and my wife and I realized what he did once it was too late. After he ate them he seemed fine but was salivating. My wife asked if I let him in when I went into the house thinking he was just drinking water but he stayed outside. My wife started to cut the lawn and he was running by the tractor so I put him in his cage so he wouldn’t get ran over.. An hour later my wife was calling me into the house, our dog looked super I’ll, huge pupils, drooling and going to the bathroom on himself and wouldn’t move at all. We took him out, cleaned him up and called the vet, they told us give him small amounts of peroxide to make him vomit it up. It was coming out of both ends and looked bloody. Took all of three hours to succumb.. he stretched out, stiffened up and took his last breath.. one of the most horrible things we had to go through. Turns out, most all mushrooms are poisonous to dogs and about thirteen other random plants in our yard that we had no clue existed or could kill our dogs.. Howell, Michigan by the way. Watch your dogs at all times, they’re like little curious kids and get into everything. R.I.P Archie.

  • Dori

    Both ginger and turmeric have long been known world wide as anti-inflammatories. I myself have an autoimmune illness. All autoimmune illnesses are known to be inflammatory illnesses. My doctors have had me on turmeric for years as an added supplement for years with no adverse effects. Turmeric should always be given in conjunction with curcumin or something else but not alone to be at its most beneficial self.Ginger, though also an anti-inflammatory has a history of being beneficial for gastrointestinal and nausea issues. The dosing of ginger must be watched closely for those taking aspirin, Warfarin or any other blood thinning products. Hope this helps on the ginger and turmeric.

  • Dog_Obsessed

    I wish this was my site, but unfortunately it isn’t. Mike Sagman, who replied to you up above, is the owner of the site and has a complete answer for you.

  • theBCnut

    You seem to be confused about whose site this is and you seem to have entitlement issues. Try doing a little research yourself. I’ll even give you a great resource.

  • Mike Sagman

    This article was published more than 2 years ago and was written with the intention of being a simple, public service list. It was never designed to be (in any way) a complete list.

    The “evidence” you are requesting here would involve a separate in-depth article (complete with references) for each individual item.

    On this website, you’ll already find a few of those posts. For example, visit the library and look for the article on “xylitol”. Or the recent article I just posted just 2 days ago that addresses the controversy surrounding “garlic”.

    Hope this helps.

  • cyndishisara

    I am wondering what you consider appropriate. Again you present no data to backup your claims.

  • theBCnut

    Ginger and turmeric are fine in the appropriate dose.

  • cyndishisara

    Fine. However, that was not made clear in your site. Actually it is the same with us humans!

  • Dog_Obsessed

    This list is talking about wild mushrooms, some species of which can be toxic to both dogs and humans. Cooked mushrooms that are human-safe are not toxic to dogs.

  • cyndishisara

    The list is given without evidence. How come? I know about xylitol, garlic, onions, and chocolate, however cooked mushrooms? Why? How about ginger and turmeric?

  • Walter Schrager

    Thnx Stephen. :) Couple pix of my little girl’s. Belle: Yorkie Cross Chyna: Min Pin

  • aimee

    It could be that each of us at one time has mentioned that study.

  • theBCnut

    Thanks aimee! I didn’t find their search function to be very helpful, but your directions got me right to it. I believe they are citing the same study that you have mentioned before. Or was it USA?

  • aimee

    Go to the homepage FEDIAF dot org. Click on “self regulation” on the left. At the next screen click on “nutrition” in the drop down under “self regulation” on the left. On that screen scroll about 2/3 down there is a link to click to go to the nutritional guidelines for cats and dogs.

  • theBCnut

    Sheesh! I still can’t get it. I also tried going to the Fediaf home page and doing a search, but still got nowhere. Is it any wonder I can’t find things on the internet?!?

  • theBCnut

    Thank, I’ll try again.

    Sent from my iPod

  • Stephen Crook

    Good – hope it’s useful

  • aimee

    Thanks for the lead. I found it!

  • Stephen Crook

    Sorry Cyndi – not what the research says

    Refer to FEDIAF Nutritional guidelines

    5-10grams/kg of body weight is enough to cause problems

  • Stephen Crook

    Sorry – worked for me

    Alternatively Google “fediaf” and the link will be there

  • theBCnut

    Your link is no good:-(

  • Stephen Crook

    Hi Walter – sent extract from FEDIAF (2008) report re Toxicity of Onions and garlic. Newest report is here – for anyone interested good document…/Nutritional…/Nutritional_guidelines.pdf

  • Walter Schrager

    Oh! and one is a three year old Yorkie cross named Belle, and my other is a ten year old min pin name Chyna.

  • Walter Schrager
  • theBCnut

    Poor pup! Bob is right. She should be ok, but will likely have a bellyache. If she does vomit or have diarrhea, fast her for a while to give her systom time to settle down before it has to handle food again. Skipping one meal is usually enough, but if her systom is really messed up 24 hrs may be necessary.

  • Bob K

    What size dog? She might puke or have soft stools. Most likely she will be ok but watch her to clean up the mess just in case. If you ate a 2 dozen donuts how would you be?

  • April Marie

    My dog just ate 3 glazed doughnuts will she be okay? There was no chocolate on them though.

  • autumn

    My dog ate vegi fried rice with soy sauce sesame oil and peas and onions
    She is, acting overly tired

  • Sam

    Is a small amount of soy sauce as flavoring safe for a small dog?

  • Ashley Dempsey

    Mushrooms? I understand you should never feed your dog wild mushrooms, but I thought mushrooms from the grocers was ok (in small amounts).

  • Dori

    Please keep an eye on you dog. You probably should take him to the vet and get him/her checked out. Could certainly wind up with pancreatitis which is very dangerous. I had a 30 lb Tibetan Terrier once eat an entire package of hot dogs that she snatched off the kitchen counter. She wound up at New York Animal Hospital for 10 days. We almost lost her.

  • diane

    My yorkie ate frozen pork chops possibly the whole pack had runny poops today

  • Cyndi

    No, not at all. I give my dog garlic on a regular basis. Your dog would have to eat a LOT of garlic for it to be even considered dangerous. Garlic is good for dogs, in small quantities. Supposedly keeps away fleas too.

  • Liz Strathman

    My dog ate some garlic and herb spreadable cheese. Is that enough garlic to be considered dangerous?

  • Sydney Geer

    My puppy that’s about maybe 3 months now ate cheese and garlic last night when we were all sleeping will he be okay?

  • Wendy

    Peanuts are not a true nut but a legume..not the same as tree nuts at all…same goes for cashews.

  • rhonda

    the only way to keep your dog healthy is to make your own, what I eat they eat, will not feed them canned food, I then know what they are eating

  • Cyndi

    I wouldn’t be too worried. Just keep an eye on him. He’ll probably get a bit of runny poop, but I doubt there were enough onions on the sandwich to cause any harm. Maybe the hot sauce will deter him from doing it again, lol!

  • teresa

    My dog got ahold of a half of a half of cheesesteak with fried onions and hots on it should I be worried

  • Shawna

    Absolutely! Is there any specific information you are wanting or just general info?

  • Samrudhi Sanjeev

    THANK U A LOT!!.This is my first dog,so could you give me some tips

  • James Herron

    You would be surprised at how many foods are not so great for dogs. A good website for checking certain people foods for your dog is:

    They also cover lots of human medicines that people commonly give to their K9s which can be very dangerous, even fatal.

  • Shawna

    Unless he has pancreas issues he should be alright. I bought clarified butter for myself but couldn’t tolerate the taste of it so fed it to my toy breed dogs (in small amounts of course) and they LOVED it.

  • Samrudhi Sanjeev

    My dog had a bit of clarified butter. should i take him to vet or is he alright?

  • carol
