At seeing the nice human who gave you a treat attacked you begin to growl. The dog that yelled at you doing the attacking. No it’s not a dog at all but another human! A human that has invaded your den and is attacking one of the pack you think suddenly. As you know the vet tech and think of her as pack as she has been feeding and cleaning your cage for the last few days.
“Leave her alone!” you growl curling back your lips showing fang to get Ruth’s attention.
Ruth scowls and gives you a look of pure frustration and smells of anger, which makes you even surer of her being a bad human.
As the vet tech finds her capturer distracted she uses this moment to try breaking from Ruth well yelling for you to attack and save her like a good dog. And you do as the vet tech has been teaching you basic dog tricks and you know if you obey her it means another yummy dog biscuit.
