While sweetcorn kernels are generally safe for dogs to eat, the cob poses a significant risk to their health.

If your dog shows any signs of redness, loss of appetite, or discomfort after consuming sweetcorn, it is crucial to seek emergency veterinary care. It is also essential to keep sweetcorn and other potentially harmful foods out of reach of your pets to prevent injury or damage to their health.
While sweetcorn can be a tasty and nutritious treat for dogs, it is essential to be aware of its limitations and potential risks to ensure your pet’s safety and well-being.
