While onions can be bad for dogs that is not likely enough to cause any toxicity problems. However I would be worried about it being fried and causing an upset stomach and pancreatitis. This can be painful and start with a decreased appetite, vomiting, diarrhea and lethargy. If you notice any of these symptoms, take him to the vet for testing and treatments.

    Oh that's not good. If Bear only ate one, there shouldn't be a risk of onion toxicity, but the fried part is concerning. Too much fat causes pancreatitis. Monitor him for abdominal pain, vomiting, lethargy, and anorexia. If you see any of those signs, have him seen by a vet. Best of luck.
