It would be nice if you would eplain your problem with my post.
You said you had treated 700 dogs. Your second post corrected that to 350, which is half the first post.
So if you had checked your source (I will assume you were the source) you would have found you treated 350 dogs. If you checked your source again, you found you had treated 350 dogs.
Combining the double source check you would come up with 700 dogs.
See?
