Licking, chewing and sniffing are calming activities for dogs.  Collagen sticks, bully sticks, stuffed Toppls/food toys/bones/trachea, snuffle mats, lickmats, are just some examples of passive calming activities.

Passive calming activities employ your dog in a positive way, keeping them busy while you read, eat, watch tv or talk on the phone.

TOP TIP:  Supervise when you dog has a passive calming activity. When your dog has finished, remove the object and prep it for later.
