Why
Small sharp fish bones can lodge in the mouth or throat and perforate the gut. Always debone fish before you give it, and never give the carcass.
Signs to watch for if your dog has eaten fish bones
Gagging, retching or pawing at the mouth
Difficulty breathing or swallowing
Repeated vomiting, especially bringing up food or water
No appetite, a painful belly, straining to pass stool, or no stool at all
Signs vary with the amount and with the individual pet, and some appear only after a day or more. Their absence does not mean your dog is in the clear — call rather than watch.
What to do now
If your dog is choking or struggling to breathe, go to a vet now. If a piece was swallowed and they seem fine, still call — an obstruction often shows itself hours later, and it is easier to treat early.
Never induce vomiting and never give any medicine unless a vet tells you to. With some substances it causes more damage than the poison. This page tells you when to get help — it never tells you how to treat at home.
Safer alternatives for dogs
Plain baby carrots or carrot sticks
Plain cooked chicken breast — no skin, no bones, no seasoning
A few blueberries or a slice of apple with the core removed
Verdicts are transcribed from the cited veterinary sources, never inferred. Where a source establishes a finding for one species only, the other species is left null and the page says to ask your vet — a dog finding is never copied onto a cat.
