Thank you so much! I completely agree, which is why I was delighted to get this prompt. My only issue was the fact that Dean clearly didn't have cynophobia on Show, and it takes a while to cure phobias and no way would Dean have wasted time on something like that. Luckily we have angels at our disposal and it did make sense that Cas would take the fear away, knowing that Dean needed to be on top of his game, as you say. :)
Glad you enjoyed. :)
