Apparently, they changed the sounds of the firetruck sirens and confused poor Itzl.
We were at at traffic stop beside the Trojan Rabbit Fire Station (that's not it's real name, just what it looks like) on the way home from work when a fire engine pulled out of the station.
Itzl's head came up and he looked all around. His head tilted quizzically one way then the other. He peered under his car seat, then looked out all the windows before he spotted the lights.
He sat there, looking at it with this "what have you done?" look, then slowly, he gave the "bad dog" sign and looked at me.
It seems we are going to be spending some time at the fire station, teaching him the sound of the new sirens.
And now I'm wondering what other sounds have changed and if he's not alerting on them because they aren't the proper sounds?
I guess I need to gather up friends and spend time siren chasing.
