I Mixed Up my Words - and It Stuck

 I've had nothing to do with training Zion.  He does the right thing by instinct/intelligence.

When we get out of the car I take of his leash and move in to the front porch.  He always lets me go first.

Then he waits until I open the front door.

I'm supposed to say "in you go".  One day I mixed up my words and said "impetigo".  I know not why.

It's now the word I use every time.  Z knows what I mean.

Here he is, in the home of a neighbour.
