The harm to dogs comes from the caramelized onions advertized to be embedded in the burgers.

I'm not sure if what I found online is correct, but this from Yahoo seems to indicate that the onions are added as the patty is being grilled. If so, I would think a customer could just request no onions.

The new burger formula will include softer, toasted buns; warm, melty cheese; and onions that are lightly caramelized because they're added to the burgers while they’re still on the grill.

Then I won’t be eating any McD’s burgers as I don’t like onions. I don’t like the taste, the texture, etc. - none of it.
