Wow. Dogs just never stop asking to be taken for a walk, do they?

I adopted a dog on my game and she has "couch potato" as a trait. One day a leash bubble popped up, so I took her for a short walk and when we got back home she still had a leash bubble... but is now also whining. The game tells me she's scared and needs to calm down. Now all she does is follow me and whine and shake about the leash. Is she so lazy that the walk freaked her out?!
