To us, it’s trash. To a dog, it can be an irresistible mix of smells, food scraps and interesting things to investigate.
Even dogs who normally leave the trash alone can surprise us. A forgotten takeout container, discarded medication packaging or something especially tempting can be enough to turn an ordinary kitchen trash can into an opportunity.
The problem isn’t simply the mess they leave behind. What’s inside the trash can could put a dog’s health at risk.
Why are dogs so interested in the trash?
Dogs experience much of the world through their noses, and a household trash can contains an unusually concentrated collection of scents.
Food residue alone can be tempting, but the trash may also contain wrappers, containers, paper products and other objects that smell like food even when the food itself is gone.
And access can be surprisingly easy.
A nose under the edge of a lid. A paw against a pedal. A trash can knocked over when no one is home. Dogs are persistent, curious and sometimes remarkably good problem-solvers.
If there’s a way in, some dogs will find it.
The danger isn’t always obvious
When we think about a dog getting into the trash, we may picture food scattered across the kitchen floor.
But household trash can contain much more than leftovers.
Medications and supplements, bones, food packaging, cleaning-product residue, sharp objects and other items that could pose a choking hazard or cause an intestinal obstruction may all end up in the garbage.
Even seemingly ordinary leftovers can become hazardous once discarded. Spoiled or moldy food, packaging and other substances mixed into the trash can create risks that aren’t immediately obvious.
That means a dog doesn’t need to get into something we traditionally think of as “poison” for a trip into the trash to become an emergency.
The numbers tell a bigger story
The risk extends far beyond the occasional stolen table scrap. In 2025, ASPCA Poison Control received calls about more than 376,000 items pets were exposed to.
Over-the-counter medications and supplements were the leading category, accounting for 16.9% of exposures, while food and drink ranked second at 16.4%.
Many of these are everyday items found in our homes and potentially in our trash. The ASPCA specifically advises pet parents to be vigilant about human food and drinks that may be accessible in open garbage.
It’s another reminder that what we throw away isn’t necessarily harmless once it’s discarded.
Prevention matters
There are plenty of ways pet parents try to keep dogs out of the garbage.
The trash can goes under the sink. Behind a cabinet door. Inside a pantry. A weight gets placed on top of the lid. A separate child lock gets attached. Sometimes the entire trash can gets moved whenever the dog is left alone.
Those solutions can work.
But they also point to an interesting problem: we’ve spent years adapting our homes around the trash can instead of asking whether the trash can itself could do a better job of restricting access.
We lock our doors.
We lock our cars.
We lock our phones.
We secure cabinets and medications when access could be dangerous.
So why doesn’t the trash can lock itself?
The question that became TRASHCAN’T
For me, that question became very personal.
My dog, Nellie, got into the trash and became critically ill with aspiration pneumonia. What looked like an everyday household accident ultimately became a frightening veterinary emergency.
Afterward, I went looking for a trash can designed specifically to help prevent it from happening again.
I couldn’t find what I was looking for.
So I started rethinking the trash can itself.
That became TRASHCAN’T: a patent-pending trash can designed to automatically lock when closed, creating an additional barrier between what’s inside and the pets and children we want to protect.
The idea is intentionally simple: you shouldn’t have to remember to engage a separate lock every time you throw something away.
A safer home can start with the everyday things
We can’t eliminate every risk in our homes, and no product can replace supervision or responsible storage of hazardous materials.
But prevention doesn’t always require a complicated solution.
Sometimes it means looking at an object we’ve used the same way for decades and asking whether it could work a little smarter.
The world has evolved. Maybe it’s time the trash can did too.
