He's a vet
You're not.

He's offering free advice based off of his experience as a vet.

What's wrong with you?

He's been to the vet.
The vet looked at him. The vet made a diagnosis.

That diagnosis was not fleas.

Had the vet who offered free advice not been such an utter prick about a comedy post, we wouldn't be having this conversation.

But
Your dog still has scabs.

So your vet was wrong.

Because
I only started the treatment three days ago.

Edit: Is there any particular reason why I should trust your opinion above all else? Is there any reason why you persist in some (frankly, odd) line to prove me wrong? Otherwise, what is wrong with you?

P.S. IT WAS A COMEDY POST.

The treatment must continue for 3-8 weeks, so I would imagine that, by the third day, not much has happened.

Unless you know better, of course.
