This is one of the most common intestinal obstructions vets see. The cob does not break down, it is exactly the wrong size to pass, and it usually needs surgery to remove. Never give the cob, and keep trash cans closed — if your dog has swallowed one, call now rather than waiting to see if it passes.
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 — it can do more damage than the poison. What we will and won't tell you.
Can cats eat corn on the cob? — A choking hazard for cats.
No — corn on the cob is a choking and intestinal-blockage hazard for dogs, not a food. A swallowed piece can need surgery. This is one of the most common intestinal obstructions vets see. The cob does not break down, it is exactly the wrong size to pass, and it usually needs surgery to remove. Never give the cob, and keep trash cans closed — if your dog has swallowed one, call now rather than waiting to see if it passes.
Watch for: 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. Some signs lag by a day — call, don't wait.
More than a taste can cause real illness, and the risk rises with the amount and with a smaller pet. The safe amount is none — if your dog has had more, call your vet.
