Hello. Thanks so much for taking the time to read this. I recently fed my dog some fish that had been cooked with onions, but before I served it to him, I rinsed the fish thoroughly under some water. So my question is, do I have anything to worry about in terms of my dog getting sick with anemia or onion toxicity? He didn't eat any actual onions, but again the fish was cooked with onions. I found out recently that onions could put dogs at risk for serious problems, & I'm so worried. Thank you.

Hello, and thank you for your question! If Dudley did not ingest any actual onions, then he should be just fine. The onion flavor in the fish should not be toxic to him. I would, of course, in the future avoid feeding him any actual onions! I hope this helps!
