Client booked walks instead of pet sitting ?

I'm new to Rover and the first client I have booked me for 3 days with her two dogs, but not to pet sit them, just to walk... 30 minutes 3 times a day (8am,2pm,8pm). Additionally they are kenneled in the same kennel and the owner wants them kept in the kennel while no one is home. This seems really sad and inhumane to keep two dogs in the same kennel for 3 days all day and night with the exception of the 3 30min walks they'll get. That means they'll be out of their kennel for 1.5 hrs a day. I feel bad leaving them at the end of my 30min but that's all I'm being paid to do. Just curious Is this typical/ normal ? Am I just being dramatic ? Thanks !
