I also want to add that it is important to keep your indoor-outdoor cats inside several days before and after Halloween.
If your dog becomes anxious every time the door-bell rings just put him in a room away from all the noise and strangers until things calm down again. It helps to leave the radio and a light on in the room. If that doesn't help, disconnect the darn door-bell and let them knock.
I'm looking forward to the 'trick or treaters'. My grandittles , Riley and Bradley will be Little Red Riding Hood and the Big Bad Wolf. Little Gwyn will be a ladybug.
Audrey wants to hand out the candy...oh goodness!
"So keep your pets safe and "Happy Halloween, everyone".
