I assume the issue with tuna is the same as in humans and that relates to mercury.
The good news, is that FRESH tuna as opposed to canned is treated like an oily fish same as salmon so is high in omega-3 fatty acids which is good.
But humans "should not consume any more than 3-4 portions a week of oily fish due to low level of contaminants" (such as mercury), and some say that is too much.
I was looking at this article recently which actually has a guide based on weight which seems to have been quoted by dog sites as well as human ones. It's very cautious on tuna intake.
Tuna: Risks and how often to eat it
I am a bit wary, as it seems to be the smaller fish like skipjack and albacore are recommended as being lower in mercury that larger ones such as yellowfin, and I'm not sure I follow why exactly, just based on size, how that would be.
And I have also read US articles that say "don't worry about fish" as its not normally a staple in dog food (err.....what??).
My rule of thumb for humans has always been tin of tuna twice a week is more than enough.
Personally, unless you are using it as a sole source of protein I think he will be a very good boy for you on the promise of some tuna
