My dog ate tuna and vomited. Is he sick or just has an upset stomach?

My dog ate tuna and threw up twice, is playing with toys lightly but acting different. I'm not too sure if it is because he doesnt feel good or has an upset stomach. Just being on the safe side.

The tuna itself isn't harmful, so I suspect he vomited mostly because it was an unfamiliar food for him that may have been too rich or salty. Keep an eye on him for any signs of increasing illness, diarrhea, more vomiting, lethargy, refusal to eat his evening meal, anything like that means he needs to be seen by your vet right away.
