TL;DR Many household items and foods can be toxic to dogs, including certain chemicals, insecticides, and human foods. It's important to be aware of these hazards to keep your pet safe.
Household Chemicals
Dogs are particularly vulnerable to household chemicals such as flame retardants and phthalates, which have been linked to an increased risk of cancer in canines [1]. These chemicals can be found in furniture, carpets, and other household items. Unlike humans, dogs often come into direct contact with these surfaces, increasing their exposure
[1:4].
Insecticides
When dealing with pest problems, it's crucial to choose dog-safe products. While some insecticides like Spinosad are also used in flea medications for pets, others can be harmful if not applied correctly [2:2]. Diatomaceous earth and Terro (Borax) products are recommended as safer alternatives
[2:4]. Always ensure that liquid applications are dried before allowing pets near them
[2:2].
Toxic Foods
Several common foods are toxic to dogs. These include chocolate, grapes, raisins, onions, garlic, and foods containing xylitol [3:1]
[4:4]. The reaction to these foods can vary significantly between dogs, making it essential to avoid them altogether
[4:4]. If a dog ingests something toxic, inducing vomiting with hydrogen peroxide may be necessary if caught early
[4:3].
Non-Food Items
While the focus is often on food, non-food items like certain plants or chemicals can also pose risks. For example, urushiol oil from poison ivy can cause allergic reactions in some dogs, although this is rare [5:2]. Additionally, dogs can handle certain substances better than humans due to differences in metabolism and digestive systems
[5:1]
[5:3].
Recommendations Beyond Discussions
To protect your dog, ensure you store household chemicals securely and use pet-safe cleaning agents and pest control products. Regularly check for recalls or warnings about pet products and foods. Consult your veterinarian for advice tailored to your dog's specific needs and health conditions.
I don't know. I don't personally go around chewing on the furniture and other things that may have flame retardant on them like clothing and what have you, so I think I might have a lower risk overall than our canine friends.
You do go around breathing the same air. If you even read the summary of the study you would see the chemical data they were gathering was micro particles that attached to the silicone collar the dog was wearing, so these are chemicals that the dog was being exposed to through simple contact. They weren’t taking stool or urine samples to see what contamination the dogs digested.
I don't roll around on the carpet either. And carpet has a lot of those chemicals in them. Mostly I have a barrier like socks on my feet.
My point is that there is a massive difference in the behavior of a person and a pet like a dog. I mean, I have cats, and they don't leave the house, but I leave the house for a large fraction of the day most days of the week.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:
https://pubs.acs.org/doi/10.1021/acs.est.4c09271
Abstract
Pet dogs offer valuable models for studying environmental impacts on human health due to shared environments and a shorter latency period for cancer development. We assessed environmental chemical exposures in a case–control study involving dogs at high risk of urothelial carcinoma, identified by a BRAF V595E mutation in urinary epithelial cells. Cases (n = 25) exhibited low-level BRAF mutations, while controls (n = 76) were matched dogs without the mutation. Each dog wore a silicone sampler for five continuous days to assess environmental exposures. Silicone samplers were analyzed using targeted and suspect screening (i.e., nontargeted) methods. Of 115 targeted chemicals, 39 were detected in >50% of samplers, with cases showing significantly higher levels (2–3×) of BDE-47, BDE-99, anthracene, and benzyl butyl phthalate (p < 0.05). Suspect screening identified that cases were exposed to more chemicals, often at higher exposure levels. For example, cases had significantly higher levels of 25 chemical features compared to controls (p < 0.05). This is the largest study to date to quantify such a wide breadth of contaminant exposure levels associated with canine urothelial carcinoma and the first to assess a population with subclinical disease, highlighting pet dogs as models to study environmental contributions to cancer risk, advancing both human and veterinary health.
From the linked article:
Dogs exposed to household chemicals more likely to get cancer, study finds
Markers of bladder cancer found in canines with higher levels of exposure to chemicals such as flame retardants
Dogs with higher levels of exposure to chemicals in common household products are more likely to have bladder cancer, new research suggests, and that may also have implications for humans who live in the same homes and have genetic similarities to their pets.
Duke University researchers affixed silicone devices that collected chemicals for five days on more than 100 dogs’ collars. The peer-reviewed paper targeted 120 chemicals, and found about 40 in at least half the pets, but the volume and number of chemicals dramatically increased in warmer areas.
Highly toxic flame retardants and phthalates that have frequently been used in household goods, and anthracene, a common air pollutant, showed among the most significant associations with markers of bladder cancer found in dogs’ urine samples. Many of the chemicals are ubiquitous throughout the home and environment.
I know this is technically not a vet directly related question but poison inside insecticide is. What products are safe to use in the house with a dog? We recently discovered an ant problem
Most products are, otherwise they wouldn’t have much success with sales.
Most powders/granules are fine, just follow the directions.
If it’s a liquid application make sure it’s dried first then it’ll be safe to have pets around.
Fun fact: a popular pesticide Spinosad is the same flea medicine you buy for your pets
So raid and that type of stuff is safe? Unfortunately the ants are at the front door and that’s where he likes to sleep while he waits for us to come home
I wouldn’t use Raid, I use diatomaceous earth and Terri (Borax) products. I keep the Terro out of reach of the pets
Is there a small area where the ants are that your dog can't get to like on a table? I like the Terro ant baits because they take it back to the colony and kills them there.

Learned this from a Facebook grandma- I find the anthills and sprinkle a mix of powdered sugar and baking soda on the hill, they don’t differentiate and eat whatever and the baking soda makes them explode
Can anybody provide a list?
Google this, look for vet source, too many to list,
It would be helpful to have a list here on Reddit so more people and their dogs will benefit.
There's millions of lists already. Do ur research If you searched reddit I'm sure ud find one already.
And if u want to rely on a reddit list rather than a vet source for what can kill ur dog, u need to do better.
Quite a few. According to HumaneSociety.
Alcoholic beverages Apple seeds Apricot pits Avocados Cherry pits Candy (particularly chocolate—which is toxic to dogs, cats, and ferrets—and any candy containing the toxic sweetener Xylitol) Chives Coffee (grounds, beans, and chocolate-covered espresso beans) Garlic Grapes Gum (can cause blockages and sugar-free gums may contain the toxic sweetener Xylitol) Hops (used in home beer brewing) Macadamia nuts Moldy foods Mushroom plants Mustard seeds Onions, onion powder and onion flakes Peach pits Potato leaves and stems (green parts) Raisins Rhubarb leaves Salt Tea (because it contains caffeine) Tomato leaves and stems (green parts) Walnuts Xylitol (artificial sweetener that is toxic to pets) Yeast dough
Thank you for posting this.
There’s plenty more info online about this! It’s a pretty extensive list beyond the one I posted. If you don’t know, always google or check with a vet if you’re concerned.
Onions, garlic,chocolate,grapes,raisins.to name a few...
Weird that it would have been much faster to type the exact same thing in Google and immediately had an answer. Who’d a thunk?
I stand by my original reply to another person.
Besides xylitol, coffee, and chocolate, this list should say things that might be dangerous in the right circumstances to your dog if they eat a metric ton of it.
Grapes and rasins should 100% be on this list. Most people are not aware because the reaction is so unpredictable. A 10lb dog could eat 100 grapes and be fine. A 100lb dog can eat a single grape and die of kidney failure.
If you catch your dog with a grape (or any other toxic food), you can give them hydrogen peroxide to make them puke it up. I did it after ours snatched up a grape from a rogue toddler, and it worked almost immediately.
Obviously only works if you catch it pretty quick though.
I was fighting this one for a while just because of the shear rarity of it happening and lack of good studies of it actually being proven to be caused by grape/raisins and not something else in the home. I just found a good documented study on dogs in kidney failure, and only 15 of 89 of them reported recent raisin ingestion. I am still skeptical of this one because the method of toxicity is unknown, and it is so very rare it just would make sense if something else was going on. Hell my old dog ate raisin bran a hundred times, and my mother-in-law's dog drank wine with her almost daily (no, I don't condone this), but yeah definitely not worth the risk even if it's less than 0.1% chance, but the odds really are less than that.
So this means I can give my doggy alcohol, just not a metric ton of it?
Cinnamon isn’t toxic to dogs
According to PetMD and PetPoisonHelpline it can absolutely be toxic.
Who upvotes this shit? A sourceless claim directly contradicting something listed in the post surrounded by other factual things and its top comment.
I mean it's toxic to humans in a high enough quantity too, but day to day it's fine.
You can feed your dog cinnamon cereals and you will not have a problem unless they are specifically allergic to it.
lol and the other one states this:
“It takes a larger amount of ingested cinnamon powder to cause problems in our pets (greater than 1 teaspoon of powder for most pets)”
Literally saying it isn’t toxic and unless consumed in concentrated form via oils it’s not a problem. Did you even read the articles you posted? You must be some sad troll coming in hot without spending 5 seconds to read anything.
Literally in the article you posted
“A small amount of cinnamon isn’t toxic for dogs—unlike nutmeg, which is toxic to dogs. But if your dog inhales the spice, it can cause coughing, choking, lung irritation, and difficulty breathing.”
It word for word says “IT ISNT TOXIC FOR DOGS”
Yes it says don’t let them inhale powder or chew on a stick but that’s true with any powder or spiced stick. You should look at your sources before posting.
Broccoli isn’t on there but my bassets broccoli farts would peel the paint off walls
Onions are pretty high on the list of bad for dogs though. All of the allium family is toxic to dogs.
A little bit isn't likely to do much, and there's a range of reactivity from dog to dog, but it's definitely something to avoid.
Most people know that certain human food items are toxic for dogs, but is there a reverse side to this? I don't mean spoiled food or dropped food or raw meat and things like that. Those can be bad for humans for the germs they have and their byproducts. I mean things, that in their basic form contain a chemical that is toxic for humans, but not for dogs.
So this isn’t actually true. Some dogs are indeed allergic to urushiol oil - the irritant in poison ivy.
It’s important to note that the classic poison ivy symptoms are caused by an allergic reaction. It’s not an actual toxin.
It’s very uncommon for dogs to be allergic to the oil, but it does happen. There are also quite a few people in the world that have no reaction to poison ivy - estimates range from 25-50%.
Carnivores are more specialised than omnivores and so they tend to have fewer ways of dealing with plant toxins in particular. There are certain foods dogs can more easily eat and digest than humans – raw bones, carrion – but that's not really the same thing.
Perhaps the closest thing I can think of is that dogs naturally produce the urate oxidase enzyme, which allows them to metabolise high levels of purines more efficiently than humans to produce allantoin rather than urate; in humans chronically high levels of urate cause gout, but dogs don't have this issue. This is not specific to dogs though, most animals do produce this enzyme and it's become lost only in primates.
A quibble: While dogs are members of the order Carnivora, they are omnivores by biology and behavior. They produce an enzyme called amylase (which breaks down starches) in their saliva and have multiple copies of the gene responsible for it — a trait more common in omnivores. Their digestive tracts are longer than those of obligate carnivores like cats, allowing them to process plant matter more efficiently. They can survive and stay healthy on well-balanced diets that include plant-based ingredients (which is why most commercial dog foods contain grains, veggies, and legumes). Many human companions give dogs carrots as treats. If you try that with a cat, they'd look at you like you'd lost your mind.
Kind of similar, dogs need no vitamin C in their diet because they produce it on their own, but it's lost to humans and some of the other apes.
Not food, but dogs (or any other mammals, aside from us) aren't affected by poison ivy.
Not quite true! Humans, some other primates, and the guinea pig all share the unpleasant allergic reaction to urushiol, the irritant in poison ivy/oak/sumac. However, while rare, other animals including dogs can get rashes.
Urushiol’s purpose is a little tricky to discern, though with the widespread lack of reaction in other animals, and the notable lack of primates in North America from 30 million years ago until relatively recently, it likely isn’t meant as a primate deterrent. One hypothesis is that it’s antimicrobial; another is that as a resin it helps the plants retain moisture.
Interesting stuff!
Dead carcasses.
Dogs like, and can safely eat, things that have been dead for a few days. It's why dog food companies add a smell to their products that isn't so pleasant to the owners: to make the food smell like a bit of decomp is happening. Humans would experience gastrointestinal illness if they tried eating the dead things their pet dog brings home to snack on.
Not a 100% sure but things like this usually involve the animal having stronger stomach acids.
They lack the antibodies to respond to it. With poison ivy, the toxin itself isn’t causing damage, it’s the immune response it triggers that causes the rash and inflammation. So we basically attack ourselves in response to urushiol.
Usually with adaptations like a shorter GI track (less time for bacteria to grow) and stronger stomach acid (kills more stuff).
Dogs also have an amazing sense of smell. You know how you sometimes eat a fruit, see that there's a bad spot, and not eat the bad spot? Maybe dogs can look at a carcass, smell the bad spots, and avoid eating them?
Watched a dog eat a recently exploded wallaby that had been dead for a week. Saw it again 48 hrs later and it was fine, owner walking its designer dog ass, none the wiser. If said owner ate the wallaby I reckon the dog would be chowing down on her corpse a few days later.
In the sense that the dose determines the poison, they can be more tolerant of medications than we are. The bioavailability of diphenhydramine for humans is about 72% and in dogs it’s 8-22%. So if I take 50 mg of Benadryl, I’m actually getting 36 mg. If I give my dog 50 mg, she’s only getting 5-10 mg. So dogs could take a lot more Benadryl before experiencing adverse effects compared to humans.
often times, when a dog eats something off the kitchen counter that they aren't supposed to, the owner will get upset with the dog and yell at them about how they could get sick. however, it's the owner's fault for not putting it out of reach.
take it from someone who has had dogs for most of his life and is the proud owner of two dogs currently, dogs have no concept of what they should and shouldn't eat. all they know is food, play, naps, and love. dogs will eat anything that is not tied down...and even things being tied down won't stop them.
as such, be the responsible pet owner and keep those objects out of reach.
Is this actually unpopular? I would hope people with dogs are smart enough to understand they are opportunistic omnivores and will seize any opportunity to grab food. That's how my brother's dog died. They had them locked in our basement apartment (where he and his wife lived) with the baby (she was sleeping). The older dog was watching the baby (fine, whatever). But the other dog took that opportunity to get into a bag of cheese puffs, and stuck her head in there trying to get them and breathed in creating a seal and suffocating herself and while the older dog seen her, she didn't jump down to do anything because she was watching the baby,
She was sealed for a few minutes and while the doctor said they COULD bring her back; she'd never be the same neurologically. They had her put down.
I absolutely think if you can't take the 15 seconds of forethought to ensure there's nothing your dog can get into that could kill them, then you shouldn't have the dogs at all. They get into things as quickly and easily as small children do, with just as much abandon.
Does your dog eat them?
Absolutely not. My old boy avoids them. My puppy is interested. I walk the yard daily. Last summer, I had about 30 different kinds in a one acre plot
So it's not dangerous to your dog
The white one looks dangerous, seems like it might be a death cap which is full of amatoxins which shut down your or your dog’s liver if consumed.
I'm afraid there are good, mixed with bad and I don't want the puppy to get one while I'm not looking.
This is the 2nd summer of different varieties popping up. Think last summer 30 different on a one acre plot
None of these pictures are complete specimens, no signs of a veil or volva so not sure how you got a deathcaps from these pics?
I don't know what to look for so, I pull them all to be safe. Figure I'm not the only one curious about which ones are harmful.
Location OP?
To get them ID'd we need complete photos of the different specimens as there seems to be a couple of different things in the bag.
Cap, stem, gills etc. :)
Iowa, I have other pics of the different types from last year, new to reddit. Don't se a way to post without linking to a diff site.

Poisonous mushrooms are only dangerous if ingested. If your dog's are probe to random snacking then it's wise to remove them. Even non toxic mushrooms could cause gastric upset when ingested raw. Sorry I can't provide an ident. You appear to have a mixed bag and not enough available details to give an accurate ident. Providing individual photos with more details and your location in the world could help with getting an ID. Hope this helps.
Thanks I understand.
A lot of people I’ve talked to don’t realize how many foods are toxic to pets. Chocolate being a dangerous food for pets is very well-known, to the extent that it seems to overshadow the dangers of other foods.
Some common foods that are very bad for your pets:
It’s also a bad idea to give your grown pets milk, as they lack the ability to digest lactose and it can cause them diarrhea and stomach upsets.

You say no milk, is this in large amounts or is sprinkling some cheese on my dog's food bad for him? ( he is a pretty big dog if that matters)
Sprinkling a little cheese on your dog’s food shouldn’t hurt them. It’s more when you start giving them actual milk or large pieces of cheese that it becomes a bit iffy, as far as I understand it.
Also tomatoes
