🪴 HOW TO & TIPS
That "toxic to pets" list is lying to you
There's a photo that does the rounds every August.
You've seen it. A grid of twenty houseplants with big red X's stamped over them, headline screaming something like "DEADLY PLANTS THAT COULD KILL YOUR DOG." Shared into every plant group, every pet group, usually by someone who means well and hasn't read past the headline.
This week is National Dog Day (seriously… it’s on Wednesday), so the timing feels right to say the thing nobody in those comment sections wants to say:
Most of that list is rubbish.
Not wrong, exactly. Just wildly, unhelpfully overblown. And I want to walk you through why, because I reckon a lot of you have thrown out (or never bought) a plant you'd have been perfectly fine with.
Let's start with the plants that show up on every single one of those lists: Monstera, Philodendron, Pothos, Peace Lily, Dieffenbachia. Basically half of what's on your shelf right now.
These all belong to the same plant family, and they all defend themselves the same clever way. Their leaves are packed with tiny needle-shaped crystals (calcium oxalate, if you want to sound fancy at parties). When a dog bites down, those crystals jab into the soft tissue of the mouth. It stings. Immediately.
And here's the bit the scary list leaves out: that sting is the whole defence, and it works. It's so unpleasant that a dog takes one experimental chomp, decides that was a terrible idea, and backs off. The reason these plants rarely cause anything serious is that no sensible dog eats enough to get serious. Most cases are drooling, pawing at the mouth, maybe a bit of sick, and it's usually sorted within a day, often without a vet visit at all.
That's not "deadly." That's your dog learning a lesson the same way it learned not to headbutt the oven door.
Now, I'm not telling you to be reckless. I'm telling you to swap panic for perspective. A plant being on a "toxic" list mostly tells you your dog will have a bad time if it decides to eat the thing, not that having it in the house is a death sentence. Toxicity is about the dose, the plant, and whether your dog is actually a determined leaf-muncher. Context, always.
☠️ The short list that genuinely matters
Right, now the flip side, because balance is the whole point here.
There are a handful of plants where "keep well away" is the real deal, and burying them in a list of twenty is exactly why the big scary graphics do more harm than good. When your Monstera and a genuinely dangerous plant both get the same red X, people stop taking the red X seriously. So here are the ones I'd actually be strict about.
Sago palm. If you learn one name from this whole newsletter, make it this one. It's that little palm-looking thing (technically not even a palm) you'll see in garden centres and as a houseplant in warmer spots. Every part of it is toxic to dogs, the seeds worst of all, and it goes after the liver rather than just stinging the mouth. This is the one where even with fast treatment, vets put survival at around a coin-flip. If you've got a dog and one of these, I wouldn't be relying on "he's never bothered with it." I'd move it somewhere genuinely unreachable, or rehome the plant.
Oleander. More of a garden and patio plant than an indoor one, but worth knowing because it turns up in a lot of UK gardens and pots. This one affects the heart, and it's serious in small amounts. Not a "sleep it off in 24 hours" plant.
Lilies (the real ones). Here's a bit of nuance the scary lists usually flatten. True lilies and daylilies are a genuine, drop-everything-and-call-the-vet emergency, but mostly for cats, where even pollen or vase water can cause kidney failure. For dogs, they're generally a stomach-upset job rather than a catastrophe. I'm including them because so many of you have cats too, and because "lily" gets slapped on plants that aren't actually lilies at all. Your peace lily and calla lily? Not true lilies. They're back in the mouth-irritation camp from earlier.
See the difference? That's three names worth genuinely respecting, versus twenty that mostly just deserve a shelf out of reach.
If your dog does eat something and you're worried, don't wait and Google. In the UK, call the Animal PoisonLine on 01202 509000. In the US, the ASPCA Animal Poison Control Center is on (888) 426-4435. Both are staffed round the clock. Quick beats clever every time here.
🐾 Living with both (without banning half your collection)
So you've got a dog and a jungle. Here's how I keep the peace, and none of it involves getting rid of plants I love.
Height is your friend. The simplest fix in the world. Trailing plants up on shelves, hanging pots, plant stands. A pothos cascading from a high shelf looks better up there anyway, and it's completely out of chomping range.
Redirect the chewer. A dog going after your plants is often a bored dog, or a puppy that's teething. More often than not it's a behaviour thing, not a plant thing. A chew toy they actually like solves more "my dog eats my plants" problems than rearranging your whole collection does.
Skip the folk remedies. You'll read that cayenne pepper or coffee grounds sprinkled on the soil keeps dogs away. Please don't. At best it does nothing, at worst you've now got an irritant near your dog's eyes and nose. Physical distance beats deterrents every time.
Know your dog. Some dogs genuinely never touch a plant their whole lives. Some treat every pot as a salad bar. You know which one you've got. Match your caution to the actual animal in front of you, not to a panic-headline written for the most destructive dog imaginable.
That's the honest version. Fewer plants in the bin, a bit more thought about placement, and a dog that's learned the Monstera bites back.
