Why two crushed pits are critical for a 15 kg dog
Crushed pear pits release cyanide much faster than whole ones because the protective shell is broken. For a dog of this size, two pits can push into the danger zone where signs like panting, bright red gums, or stumbling appear within an hour. The fact they were already crushed means the toxin is likely already being absorbed—this isn't a 'wait and see' situation.
While some dogs might pass a whole pit without issues, the mechanical damage from chewing plus the cyanide risk makes this a double threat. Watch for drooling or retching, which could mean fragments are stuck in the throat or stomach lining. Time matters here: call while you're checking for symptoms rather than waiting for them.
Handling the other dogs without delay
Though the other dogs didn't ingest pits, compost often contains moldy food or bacteria that can cause stomach upset. Run a finger along their gums and under the tongue to check for hidden fragments, especially if they were nosing around the same area. Wipe their paws with a damp cloth to prevent them from licking off any residue later.
If any of the dogs are under 5 kg, even a fragment could be risky—but in this case, your focus stays on the 15 kg dog who definitely ate the pits. Separate all pets from the compost area immediately, using baby gates if needed, while you deal with the emergency.
The first hour after ingestion is key
Cyanide poisoning moves fast, and symptoms often appear before you'd expect. Your dog's weight buys a little time compared to a tiny breed, but don't rely on it. If you notice dilated pupils or trouble breathing, mention these details to the vet—they indicate the toxin is affecting oxygen transport in the blood.
Don't try home remedies like hydrogen peroxide, which can worsen throat damage from pit fragments. The vet may use specific antidotes that only work under medical supervision. Grab the compost bag or any remaining pits to show the vet—they'll want to confirm the type and amount ingested.
Longer-term monitoring for all dogs
Even if the unaffected dogs seem fine, watch for diarrhea or lethargy over the next 48 hours—compost can harbor toxins beyond just fruit pits. For the dog that ate the pits, recovery depends on how quickly treatment starts. They may need blood tests to check oxygen levels or IV fluids to flush the toxin.
Prevent future access by storing compost in a locked bin or elevated container. Pear cores should go directly into outdoor trash, not left where dogs can scavenge. If your dog recovers, ask your vet about checking for intestinal irritation at their next regular visit.
