when you give Tia a treat, the interaction is not over. it has only begun. you can't just put the treat bag down. if she knows the location of the treat bag, she'll continue to pursue it relentlessly, jumping on stuff and committing crimes until it's hidden from her in a place she knows she can't reach with paws and teeth. she'll open drawers. i have seen her knock down a decorative paperboard box and pull the lid off in pursuit of treats. if she gets her mitts on it, she'll chew it open. so i've taken to giving her a treat and then hiding the treat bag while she's eating, because i don't want to have to get up and open my closet every time she needs a treat (i also use the treat to reinforce good behaviors. or to bribe her. sometimes the only way i get my chair back is bribery, okay)
she's gotten wise to this. i was just quietly trying to sneak it behind something while she was eating, and she turned around while chewing and locked on to the new treat bag location. swear to god there was a z-target noise.
