Corrections are the most useful thing you can send.

If you are reporting an error, including the page address and the figure you believe is wrong makes it much faster to fix. Errors are corrected at the source data and the page is rebuilt, so a correction sticks rather than being patched over.
What we cannot answer
We cannot advise on an individual animal — not what to feed it, not whether something it ate is dangerous, and not what its symptoms mean. That needs someone who can examine the dog. If something is wrong with your animal now, contact a vet or an emergency veterinary service rather than waiting for an email reply.
