Jack Russell Terrier vs. Snake

I'm sorry "Jpngrish"
To the people that this looked like a venomous snake...
It might be difficult to distinguish with the video only.
However, this is just a Rat snake.

Of course there is no poison.

I had known this thing since before.
I have encountered the snake many times.
I can instantaneously distinguish whether this snake has the poison or doesn't have it.
In addition, Poisonous snakes does not live in my region.

Momo lives with me in the
