Hi Hackernews!

I’m thrilled to announce the launch of IsItToxicForMyDog.com, your one-stop shop to answer the question: “Is this human food toxic for my dog?”

Designed for simplicity, the site features what I believe to be the most extensive database of annotated human foods out there. Type in a food and the site will respond with a clear indicator, “SAFE” or “TOXIC”, that you can use as guidance when giving your dog human food.

Please do not take the information presented on this site as a substitute for medical advice. In an emergency, always call poison control or a veterinarian instead.

I’d love to hear feedback from the community here. Please comment below if there are any bugs, issues, or feature requests that come to mind.

Thank you all!

It'd be cool if you had a link to the list available as a web page instead of a web application for when the JS fails to load.

That way when search engines index it people could actually find the information too.

Any geek with 2 seconds can load up https://www.isittoxicformydog.com/static/allfoods.json and look but putting this in an actual HTML webpage would help out search and discovery lot.

I tried the last thing I had to google before I gave it to the dog (zucchini) only to find there wasn’t an entry.
How did you determine the toxicity and where are you sourcing this data?
Instead of a blank start page, why not display the top 10 most common things a dog shouldn't eat/chew?
No indication of “it's toxic if your dog eats an entire 2lb bag” vs “it's toxic if they eat a 2 gram slice”, no indicator of where to get more information.

Kinda feels like the classic “every symptom means cancer!” issue common to medical databases for laypeople.

And how are there 5 varieties of almond butter listed, but not almonds themselves?

“Almond Milk, Unsweetened: TOXIC”, and yet every site I've looked at says it's fine in small amounts.

A lot of things are probably toxic if a human eats an entire 2lb bag of it.

The dose makes the poison.

Which is why it's important to disclose the dosage
unless anaphlaxis?
I mean, sure, just like some humans might get anaphylaxis from peanuts. That doesn’t mean that peanuts are toxic to humans as a whole.

The problem with the site is there’s no gray area when the reality is that it very much depends on your dog and their size.

It's a bad sign that the first several things I checked are all wrong.

https://www.akc.org/expert-advice/advice/can-dogs-eat-rice/ says brown rice can be hard to digest but is otherwise fine, but this still gives that skull-and-crossbones-surrounded TOXIC indicator, as if I'm gonna kill my dog if I don't have his stomach pumped after he gets into a plate of it.

Our vet recommended a chicken and [white] rice diet for diarrhea.

They don't digest it well, which is apparent when it blows out everything in their guts, bile and all. It's probably not great for gut flora if eaten all the time but it's not "toxic" in itself.

It says Watermelon is toxic. I don't own a dog but I did a bit of Googling and it seems to say the seeds could cause some blockages?

That's not toxic...

In this part of the world (South Asia), dogs regularly eat rice, and in fact prefer it. Okayed by vets too.
This seems to be the answer to why my initial query of apple was reported as fine but apple juice was reported as toxic
Definitely worth adding xylitol. It's used quite a bit in chewing gum and some sugar-free stuff, and is quite toxic to dogs
Yes. Also in quite a few brands of peanut butter, which is a favorite treat flavor for many dogs.
neat, but tbh there's zero chance i'm going to remember this next time i need to find out if something is toxic for my dog. google knows the answer
Why is “beef and broccoli” toxic but neither “broccoli and cauliflower” nor “beef with potatoes” are?

I’m not a dog owner. I visited the site mainly out of curiosity.

It's an American Chinese dish that contains garlic and onions.
That's... a really dumb way to say that garlic and onions are toxic though.

Context is crucial!

I like that you limited it to only a known set of queries.

How did you vet the set, to be certain that it won't ever say that something is OK when it's toxic?

I love the intention behind this, because this is information I search for regularly, but the build feels lacking a bit at the moment.

The biggest problem is that any site which attempts what you're aiming for would need to offer me more than my current approach, which is just to Google "[food] safe for dogs", which returns me:

A. Multiple sources of information to cross-reference the results, increasing my confidence in the answer. This site only gives me a YES/NO result with no(!) indication of where the information is coming from. You should definitely add a list of sources for the information below the results. For instance, my second search was for blueberries, which all the results on the first page of Google say are safe for dogs, but your website declares TOXIC. Mistakes like that will instantly kill my desire to trust your single source of information.

B. An indication of what level foods might be toxic to dogs at. As other commenters have mentioned, it's not a binary result. A note below the result quoting one or two of what your sources say about levels of toxicity would be really helpful.

Also, just from a usability perspective, when I start typing a food into the search bar and the list of autosuggestions appear, I was expecting to be able to hit the down arrow to start going down the list and hit enter to select the result I want. Making me go back to the mouse to select the answer I want was an (admittedly small) point of frustration).

About a year ago I went down a rabbit hole trying to find out why grapes were listed as toxic for dogs. I found many many anecdotal cases of dogs eating grapes without harm. A few reports of dogs dying after eating grapes. A couple of studies concluding grapes were toxic based upon a rather astonishingly small number of cases. Mostly I found references to references to references ad nauseam where the certainty of the claims increasing proportionally to their distance from any actual data.

I ended up feeling like they are about as toxic as peanuts are to humans. Maybe quite bad for some, evidently harmless to others.

Humans have been cultivating grapes for millennia and dogs were there, literally enjoying the wind fall.

So feeding your dog a few grapes doesn't make you a bad person.

It does make you someone who is likely to step in dog diarrhoea during the night though, depends how many grapes "a few" is, as how small your dog is.

I found this out the hard way as a kid. There was quite a few diarrhoea incidents I had to clean up in the morning.

The best part of having immigrant parents is that we've been feeding dogs things for 40 years+ without a care in the world what the Internet even thought or said.

We've always fed our dogs, usually shelter dogs that came to us at 6 months or older, grapes. And basically everything else people say is bad for them too I'm sure.

Couple notes:

1. Google and Amazon smart speakers do a surprisingly good job with these kind of queries and work better as providing a more frictionless means of getting an answer to these types of spur of the moment questions.

2. Claiming to have one of the most extensive databases around food related toxicities for dogs and not immediately providing a link to the sources of your information on your website is a big red flag.

According to this, chicken is toxic for dogs? And "water, bottled, plain"?
Apparently lots of dogs have or develop allergies to chicken or chicken products in dog foods (and fried chicken usually has spices that may be bad for dogs like onion powder or garlic powder).
Allergies are not the same as toxicity.

Many humans are severely allergic to peanuts, but nobody would expect peanuts to be labeled "toxic" for that reason.

(That also doesn't explain "bottled water" being listed as toxic. There's something very wrong with this data.)

They have to eat cloves of garlic or whole onions for it to be poisonous.

It's toxic to them like alcohol is technically toxic to humans. Kidneys and liver filter out what they can enough to survive casual consumption. Some people can drink an entire bottle of vodka; most people shouldn't.

(comment deleted)
Plain bottled water is toxic to dogs?

Also it was not obvious to me that just because it showed the “toxic” message with icon that was the answer. I just thought it was some slow loading logo thing that was slow to load. That is the answer, right?

And what is “baby water”? Or “enhanced diet/regular water”?

All water, according to the site
I've raised 3 dogs from pups to death (~14 years old) and they've all consumed water during their lives. Coincidence? I think not and this site agrees.
Apple, water, broccoli, bear (yes, bear), all are toxic. Beaver, on the other hand, is fine. This might be the candidate for the stupidest HN submission that somehow received a non-trivial amount of votes.
The biggest issue with every one of these websites: dogs are amazingly size-diverse. They range from a 4lb chihuahua to a 200+lb mastiff. If humans were similarly diverse, we would run from 60lb dwarfs to 3000+lb giants. Poisons are all about the dose, or at least the dose per mass of dog. A Hersey bar that might kill or at least cause suffering for the chihuahua will likely do absolutely nothing to the mastiff. Dogs are also very diverse in health and constitution, from very sensitive purebreds with allergies and strong reactions, to resilient mutts that shrug off most things. So trying to create a website of what is and isn't deadly to "dogs" in general is very difficult.

Maybe a website about poisons for house cats. They range from perhaps 5 to 20 lbs.

+1 for cats.

But yeah be careful with the dispensing of medical advice, someone is going to feed their pet something toxic and then sue because your site said it was okay.

most american/anglo content ever.

why can’t we just take knowledge from others and recognise that we have some obligation to ourselves to use our brains?

Unfortunately, because lawyers want to profit.
This site https://www.petmd.com/dog/chocolate-toxicity has an input where you enter the dog weight, type of chocolate, and amount consumed, then it plots your "danger level" on a sliding scale. Would be fantastic to have that for more substances, but I don't know how solid the canine "LD50" data is in general.
Related, the verified record holders for lowest and highest adult weights are (by species):

Canis familiaris (Dogs): ~371x difference

      0.45 kg |    1.   lb | Milly       | Chihuahua
    167.   kg |  368.17 lb | Benedictine | Saint Bernard
Felis catus (House cats): ~31x difference

      0.68 kg |    1.50 lb | Tinker Toy  | Blue Point Himalayan
     21.23 kg |   46.8  lb | Himmy       | Tabby
Homo sapiens (Modern humans): ~298x difference

      2.13 kg |    4.7  lb | Lucia Zarate
    635.   kg | 1400.   lb | Jon Brower Minnoch
Edit: Formatting
Given what I know about humans, Lucia was obviously a newborn. I'm less confident when it comes to dogs so I don't know if Milly was a baby or not. Either way, doesn't including babies throw things off a bit?

I feel like the the difference between the smallest and largest adult dog is much bigger than the same ratio in people, unless there is a person with very extreme dwarfism or something.

This is Lucia Zarate's adult weight, recorded when she was 17. She had Majewski osteodysplastic primordial dwarfism type II, which is hereditary.
Wow, I stand corrected. I did not think that was physically possible for a person.
Neither of the people on either side of that scale are what anyone would call "healthy". A 4 lb dog can be completely normal and healthy, so too a 200 lb mastiff. A 2-lb person will not be healthy, nor any 1000+lb person. Those are nano-percentage outliers.

Fyi, the wikipedia entry for Lucia Zarate cites larger numbers, as much as 14 lbs.

“grape” returns about 40 different serving sizes and formats of grapefruit, and doesn’t list grapes (until you add “s”).
Apparently, me feeding my dog some cooked boneless chicken is poisoning them...

I am sorry but this is terrible and almost outright misinformation.

Even toasted whole wheat bread is marked as toxic.

Unless you add raisins. Then suddenly it's okay.

In the real world (third world) street dogs thrive of garbage.

What is an “alexander” and why is it toxic to dogs?
Anyone know the science behind why grapes are bad for dogs? It was a mystery, last i checked.
I wouldn't ever describe human food being toxic to animals as a mystery: We have good reasons to prefer crops that are harmless to us but unattractive to potential pests.

And just by biological accident we would expect some plants to have toxins that don't harm us but harm other animals... we're going to want to grow those things.

Right, gut instincts and conjecture like that are all we have to go on.

A scientific reason something is poisonous involves specific chemicals and their effects on the biological system

I'm not an expert but I've heard they can be a choking hazard.
There are things that are listed as toxic which are not.
I think it is a tongue-in-cheek satire website. I searched for "water, baby" and it says it is toxic. It's quite funny
I am pretty sure cooked noodles are not toxic for dogs (though they should not have them in large amounts)
Cool website! But I thought the website would tell me which human foods are toxic for dogs. (Like, a list? I'm assuming it's not an enormous number?)

Instead, there's only a search bar, and I have to check every food that exists, manually!

Edit: another comment posted a link to the data, >5000 (variations of) meals

  {
    "id": 2343660,
    "name": "crackers, sandwich, cheese filled (ritz)",
    "is_toxic": 1
  },
  {
    "id": 2343655,
    "name": "crackers, sandwich, peanut butter filled",
    "is_toxic": 1
  },
I can't tell which part of this is actually toxic... possibly an ingredient that isn't named?

OP, did you generate this based on a much shorter list of ingredients which are known to be toxic?

this thread is dramatic evidence there's demand for this product.

that said, I have to echo some of the other folks here: this tool is not useful for determining the risk to my dog.

problems: - items known to be not-toxic are listed as toxic (water?) -items known to be toxic are not weighed higher than non-toxic items in search - items with dosage dependent toxicity don't expose that toxicity (onions are toxic, my dog would need to eat several raw onions to have any toxicity) - items known to be extremely toxic in low dosages (like xylitol) aren't present - the toxic component of dishes aren't listed

I tried searching « chocolate », and I have to select an option in the list (chocolate beverage powder dry mix, chocolate beverage powder light dry mix…)

I want to search just « chocolate »

how would an egg and bacon burrito be considered toxic? Maybe not good for a dog, but toxic?
So "peanuts, dry roasted, unsalted", "peanuts, dry roasted, lightly salted" are toxic, but "peanuts, dry roasted, salted" is fine, sounds good.
